Possible motherboard or power supply failure?

Q: Possible motherboard or power supply failure?

Starting in March this year, my Lenovo B520 AIO started to abruptly switch off after running for varying periods of time. During the first week, this would happen after the computer had been running for 3-8 hours, sometimes while I was actively using it and sometimes while I was not using either keyboard or mouse, but while the screen was on. during the following couple of weeks, the machine would switch off after being turned on and running for only 5 to about 20 minutes at the most. I stopped using the machine at this point in April. I've tried a few more times since then, using these short periods of activity to keep up to date with Windows 10 updates. All Lenovo drivers are at the current update versions. Does this sound like the power supply is failing or could it be another problem. I'd like to repair the problem as simply and inexpensively as possible. Thank you in advance for your advice.

As the title suggests, my Lenovo h50-55 may have a possible PSU/Motherboard issue. Because upon turning it on the screen is basically black but the tower will still come on and all the fans will spin still. I have tried taking the ram out and swapping it around, taking the graphics card out and using the monitor ports on the motherboard (VGA) and nothing works. It also doesn't beep or anything upon turning it on and the HDD light is very dim. I orignally thought it was a HDD problem but i managed to install windows 7 on it and it worked perfectly. The monitor works fine too, as i plugged a games console into it and it's fine. Yesterday a family member took it to a PC repair shop and i wrote everything down that i had attempted on it the tower, but he claimed the power supply was "16" and it couldn't be tested to see if it was broken. As modern machines have "20-24" regarding PSU, but i have zero clue what he is talking about and i'll have to call him today and ask lol. I really like the machine too and i don't want to replace it after only having it for two years, so any help would be great. Thank you.

I've read a few threads here on these forums and have found a few similar situations but nothing that really matches what i'm dealing with. Here goes:

I was playing a game when my PC made a short strange muffled hissing noise and then popped. The PC completley shut down like someone has pulled the plug. Almost right away it smelled like an electrical fire. I figured this was the power supply (NZXT 550W) since it is around 4 years old and has been through a lot.

The following day I went to best buy and picked up a Thermaltake TR2 600W PSU and installed it. After plugging in the main power cord from the wall outlet I switched on the PSU itself. Inside, the SB PWR light on the MB lit up. I thought this was good news. I hit the power button for the whole system and
the CPU fan moved slightly and the front LED light quickly flashed on and off. Then nothing. I checked to make sure all connections were snug. Same result.

Hi, I just bought an HP pavilion e9300 a few week ago. And I am going to upgrade the power supply so that I can get a new graphic card--ATI 4870 which requires at least 500 watt power supply. My current computer is shipped with a 350 watt power supply. I will probably get a 650 watt considering the 70% effeciency of power supply.
However, when I talked to an HP technician, he insisted that I could go for a power supply with no more 450 watt. Because the system I just got has a motherboard which has a max power limit 450 watt. He said if I go beyond that, the motherboard will burn out.
So what shall I do? I really want to get ATI 4870 work well on my computer.
Thx very much.
 

A:Does power supply with higher power rating really burn motherboard?

The long answer is "No".
Just be sure of the dimensions of the power supply before you order a replacement, as HP uses some pretty strange sizes sometimes, and you want the new one to fit with room to spare.

I have a Sony VGC-RB42G computer. I recently moved my computer, cleaned off all the dust, and when I plugged everything back in, it won't power up. The light on the power supply blinks green, inside the motherboard also has a green light that blinks as well. It has a ticking sound too, but I am not sure if it is coming from the power supply or the motherboard. Any idea what could be wrong.

FYI, I have already unplugged everything from the power supply, pulled out the ram, checked the battery, and put everything back together and still no change. One thing I thought was strange was after I unplugged everything, I pulled the power into the power supply again and this time the green light came on but did not blink. It stayed solid.

First time I have ever seen that feature. I like it. I'm thinking that is a neat/easy way to partially eliminate cable clutter from the PSU. Give it a shot, you can always revert to PSU cable if you wish.

Ok so lately I have been getting a BSOD at very random times and it looks like a Diver Power State failure. SO all of my friends and every website I go to makes it seem like I need to get a PSU. Right now I have a Quad Core and a 8800GT and 375W PSU. So my friend told me to get a new 700W PSU.

So, if the only fix is to get a new PSU? I tried to rollback my GPU driver but it didn't help.

So any ideas?

You're greatly risking the health of your whole computer while running with such underpowered power supply. Do yourself a favour and get a quality PSU. http://www.newegg.com/Product/Product.aspx?Item=N82E16817341010 That's the cheapest one that is enough and of good quality that I could find with a quickish search.

My machine has been acting rather funny within the last few weeks. I suspected it to be a virus, but that possibility has been completely ruled out. My computer specs are:

AMD Athlon 2ghz
Geforce 4 TI 4200
512 mb ram
333 mh ram
PC 2700

The problem is that she's getting increasingly slower. Start up is taking ages now. When I run music it takes up nearly 90% of my CPU. Starting up another program while I have music running will skip the music for about 3 minutes at a time.

Programs are taking longer to start up. Yesterday my CD drive wouldn't even open, I had to restart my system. The printer takes forever and my download rates are suffering dramatically from what they should be.

My husband suspects it to be a problem with my power supply, but I'm wondering if there's any other possible problems.

No, I don't have any trojans, viruses, or backdoor spyware running. I've ran at least 6 different programs to detect these things.

Thanks in advance for any advice.

he said the computer was working fine last night but when he switched it on today it wasnt booting up and was asking for a disk or something, i automatically assumed that he had a hardisk problem n told him to power it down and i would be round to have a look at it.

i went round earlier tonight and the computer wouldnt switch on when pressing the power button.

checked the power cable and that it was turned on at the back of the tower, do i have a power supply failure?

My computer has been dead in the water for several weeks now and I am not sure what the problem is. I think an electrical storm may have fried my power supply, but I am not sure. Here are the specs on my "clone" system:

MB: Intel D101GGC (w/onboard audio and video)
CPU: Intel P4 511 LGA775 (04A Platform)
PSU: RaidMax ATX 12V 380W
RAM: 1GB (2-512MB) PC-3200 Single Channel
DVD: Sony 16X
CDRW: Sony 52X/32X/52X
HDD: Maxtor SATA 200 GB 7200 RPM

When I opened up the case and looked inside, with the power cord plugged in, the motherboard has a green LED light that indicates the MB is receiving power. When I tried to turn on my computer I guess it is the CPU, but it makes a funny clicking sound and the the fan over the CPU tries to turn, but stops immediately. When I turn the fan blade with my finger it turns freely, so I know it is not the bearings in that fan. I have been to Intel.com and followed all their recommended steps to troubleshoot this problem, but no solution, as of yet. I have unplugged all devices from the power supply, except the 4-pin (12V) power connector and the 20-pin main power connector and the CPU fan and nothing has changed. What else can I do? What is a definite indicator that it is a power supply problem and not a MB or CPU problem? Please Help! Thanks!
 

A:Power Supply Failure?

Have you also unplugged the HardDrive and CD/DVD drive, and floppy (from the motherboard end)?
Remember you just want it started

The fan may be thermostatically used, that is it won't start running until the system is warm.

Reseat Ram?

Ideally test with another PowerSupply
Here's a good BenchTest Guide

You should also try dispersing all internal voltage, by holding in the power button for 30secs whilst the power lead is out.

I'd also recommend removing any internal PCI card attached
I've even have faulty CPU fans cause this error

You always need a good power supply anyway as it prolongs your components life. I would recommend Antec, enermax or corsair for a power supply. Saying that it might be "dead RAM". If the RAM is not working properly the computer won't start. Got any friends who will borrow you a power supply for testing?

The past 2 weeks, I've had to press my "Power On" button 2 or 3 it before it comes on. This happens about every other day.
The last time this happened, I had to replace the power supply and that was only 2 years ago. Surely they last longer than that?

Also, is it ok to leave my computer on 24/7 until this gets resolved? I'm afraid that one morning I won't be able to turn it on.

Hello,

I live in Rancho Bernardo, CA and when we were evacuated, I disconnected my desktop and took the computer case with us. It was in the trunk of my car for 4 days. (not good!) After returning home,(we were one of the fortunate families) I reconnected my computer and started it. It posted like usual, went to the XP startup screen and then went to the black screen that gives the options for safe mode, etc. I tried to start it in safe mode but it would not. It only opened some of the start-up files and then stopped.

I reseated the ram, video card and disconnected all of the drives other than the HD. I tried the "normal start". Same thing happened. I changed hard drives, put in another video card and restarted. The colors then changed to something other than normal, butt still would not boot past the startup screen before the welcome screen. It goes to black and there is a flash of a blue screen with text on it but it does not stay on long enough to read. I also tried the "last working configuration" with the same results.

The cooling fans now seem to speed up and slow down in a cycle. The bios shows normal voltage to the processor and the temps look normal there. I have a Antec Sonata with a 380W Power supply. It is 4+ years old. It only has one 12V rail. Could this be my problem?

A:Power Supply Failure?

I am a little confused. does the computer run and just not boot?

typically a PSU will blow and never turn back on. on occasion (as happened with me) a faulty transistor will cause power to cut out after the computer is on for a little (this prevents damage to the board and other components).

if you disconnect the harddrive, and power up to the bios screen, does it run okay?
also, have you tried a memtest? http://www.memtest86.com/

if the computer runs for awhile with no HDD, then it is most likely a HDD or software problem

My desktop kept restarting itself anytime I try and do anything very intensive (games or movies) for very long (20 min to an hour). No BSOD, and infact when the computer shuts off, it turns back on and then "begins" shutting down (as though it never finished the sequence). I had this problem until I replaced the PSU. Now the problem has returned.
I just purchased a new PSU a month ago, as my old one tanked after a year(750 Watt 80 Plus Gold EVGA) and replaced it with the 1300 watt model. I could understand such a low watt model tanking after a year under the load I had, but the new one going after a month? What is the likelihood?
I'll start from the beginning: 18 months ago I built myself a new setup. My power supply failed around 3 months ago, it was an EVGA 750 watt 80 Plus Gold, and when I used my PSU tester at least half the lights never lit up.

A couple weeks ago my computer all-of-the-sudden stopped turning on. When I press the power button, the lights turn on and the fans start spinning for less than a second, then everything turns off. If I press the power button again, nothing happens. I can get the computer to turn on for a split second again if I either unplug the computer, wait, and then plug it back in. The first thing that came to mind is that the PSU has died. Does this sound legitimate?

If the PSU has died, does anybody know of an inexpensive replacement that would work with my mobo and power needs? Thanks!

Typical of a power supply failure.

And the HP m7650n does not have enough power in the supply for that GeForce 7600 GT.

Borrow a power supply to test in yours, or get yourself a power supply tester such as the Apevia Power supply tester for about $10 - $12

Or just buy a new and quality power supply... locally or on line.

You have to be very careful to get one of the exact same size dimensions and with the same sockets... If you don't have a source, www.directron.com has a huge number from which to choose.
Good luck.

Hi! I have a computer (or maybe had) with an Asus M2v-MX SE motherboard with a dual core AMD processor, running XP Pro SP3. Over the last few months. maybe once every week or 2 weeks, it would freeze after booting into the OS. Mouse would freeze and couldn't crl-alt-delete to task manager. I had to unplug it, then reboot and it would be fine. The other day, as it booted the boot message screen came up in different colors within words, then everything had a green hue. The green hue continued after the OS came up. I was just checking mail before I went to work. When I came home, I turned on the computer---and nada. It didn't do anything, and a message appeared on the monitor---no signal. Not even the bios came up. I use the onboard video, so with the green hue I figured Motherboard. But since it sent no signal, now I'm thinking power supply. How can I determine the cause of the problem? I know I can't find a replacement motherboard---it's 7 years old. A month ago, I put in Crucial CT2KIT25664AA667 4gb, but I don't know how this would cause this problem as it hasn't froze since I installed the ram. Any and all responses will be greatly appreciated.

I was replacing a fan in my case because it made a high pitched sound.

It still made the sound so i plugged the molex back into the 2 molex to 6 pin connector and the computer shut off immediatly. Now when i hold down or just push the on button my led flashes and fans spin and stop repeatedly. Any Help would be just the best thing right now.

A:Motherboard or Power supply

NEVER unplug or plug in anything except maybe case fans inside a computer with it powered up! Pull out the video card and see if the computer powers on. If it powers on you have fried the video card. If the computer still doesn't power on, the power supply should be changed before you suspect the motherboard

I am working on my aunts PC (HP slimline), again! This time it will not turn on, seems relatively easy problem. I press a power button and exactly nothing happens, not even PSU fan spins. I do not have a tester for FLEX PSU (they have that tiny 24pins and not regular size ones), but I take it out and cross the green wire (PSU on) with black ground wire and the PSU turns on, hmmm. So I independently test out each voltage on all wires and they all come out with proper voltages.

I put the PSU back in and I test out the power button and its wires, and they are fine. I even crossed the pins on the motherboard to get it to turn on and nothing.

The thing I can not get my head around it that in every motherboard failure I was a witness to, I was at least getting some PSU response (fan spinning). That is why at first I thought it was PSU for sure, but I do not have spare FLEX ATX PSU as they are not common at all.

Would I be wrong to assume that motherboard went south? The way I see it, ifI get a new motherboard (for a lot less than new FLEX PSU) with standard power supply plug I can just put the PC into normal chassis (I have spares) and use one on my many spare ATX PSU's and eliminate both possible sources of error weather it is a motherboard or FLEX PSU.

Thoughts? Thanks...

Hi, I'm on a mission to patch together some kid's emachines T2682 P4 pc.

The fans run, so I think the power supply is ok. I removed the ram, still no beeps, no video signal. I'm set to order another board, but I read where in most cases the power supply is what causes the mboard failure. Should I get a power supply and try that first? Is there a way to just check the ps?
 

A:Power supply or Motherboard?????

I would replace the power supply at the same time as the mother board. I had a faulty supply that seemed to work, on an Emachine that was under warranty. It blew the motherboard and keyboard and a wirless adapter that was pluged into the usb port at the time. they replaced all the parts but the wireless adapter because that was my own part. They put in a used power supply and just after the warranty it went out again an took the motherboard with it again. I took out the harddrive and threw the rest in the garbage. No more emachines for me. It was cheap and used as a second computer for the grandkids so no loss.

Hello, I need your advice please.

I have a system based on a Epox 8KHA+ with the latest BIOS. 512MB RAM, AMD XP2000+ not overclocked, running at 56 degC., Windows XP fully updated.

The problem is the system keeps turning itself off. After about an hour of running, it suddenly dies as if the power plug had been removed. If I try to restart using the power switch nothing happens. If I then unplug the power lead and replace it, it then starts up OK.

Any ideas please?

Case #1:

Heres the thing, I went to a friends house (wolvman on here) and was getting it set up. He told me that because I needed a hard drive still, and that neither of the raptors he gave me worked, he had a 160 gig IDE drive. I plug it up, having to unplug the side fan, because all of the power supplies I have are limited to 6 ( I think ) legacy connections.

I start the computer up, nothings wrong, but its lagging a little due to the system (XP home) getting drivers, etc. for the hard drive. It comes up and says its working, so I check it, and it was. It had a previous installation of XP on it, so I see everything. We then decided to play CS:S, and about 10 minutes into it (it was running fine and dandy) it just shuts off. First I think that the GPU went out, because I didn't notice the computer went off, just that the monitor said "No signal", but it went completely off.

I proceed to try to turn it back on, and it does NOTHING. I pulled the side of the case, and checked how hot it was. The Power Supply was pretty freaking hot, along with the GPU, CPU, and HDD's. This is where I get scared. First, I think it just overheated and shut down, but then I realise that that's usually a BSOD, correct? Would the HDD's usually get that hot? Its a simple Maxtor 160gig, I believe its 7200 RPM.

A:Either Power Supply Or Motherboard went out

Maxtors fail way too frequently. Next choice is the power supply. Watch from the back with a strong light when the <ON> button is pressed. Does the fan blade turn four revolutions or less. That is a bad power supply.
There is no relationship, really, between heat and a BSOD. It can just as easily shut down as give you a BSOD.
I'm betting it is power supply, memory module, or Maxtor failure.

OK here is the chain of events....

Turn off computer at 3:08
Had pizza
Power Up computer at 3:20

While I'm walking away I think I hear a rather remarkably loud beep, or maybe two beeps. Either way when I come back to my computer it's powered on however, the monitor shows "No SIGNAL"
I go through the standard, try the monitor on another computer, check the cables etc.
After a few more tweaks I power the computer up. Still no signal. Another power up later I notice there is no POST beep.
I check everything and try again. No post. I reset CMOS, no post. I notice at this moment that the VIA chip fan isn't spinning.
I unplug all peripherials and try again no POST the computer comes on for a brief second then everything stops, the PSU fans, computer fans everything.
Now that's all I get it's like the car starts but doesn't turn over.

I'm assuming this is either a powersupply problem or a mother board problem. How do I narrow it down? My MAJOR concern is I have 2 segate drives RAID ed (the one for speed, 1 I think) if I get a new mother board I need to keep this info is that possible? So I guess in order of priority here are my questions...


1)How do I get my data off my Raid drives?
2)Is this a PSU issue? Or a Motherboard issue?

Sorry about the meandering nature of the post but it's 5 am and I'm really out of sorts worrying about this. Thanks in advance.

Check to see if the CPU was installed correctly and have not come "loose". Also check the pin that powers the CPU fan and see if it is seated securely.

Hi

My pc won't properly boot up (i.e. all the fans turn, but there's no video input), so I have troubleshooted all parts. Eventually I put my PSU in another computer, to find that that one didn't boot at all. I concluded the PSU had to be broken.

As a last test I used a multimeter to manually test the voltages of the 24-pin connector and found that they were all next-to perfect.

Does that indicate that the PSU is healthy, and my motherboard must be dead?

No. It just means that under essentially no load the PSU is delivering the proper voltages. The voltages supplied under load may dip well below what they are supposed to be.

OK, I'll try to get it right.......

I have an Intel 2.6 Ghz Duo Core on an ASUS Motherboard, 2 Gig RAM and all about six years old running Windows 7 Pro.

When I do a cold bootup from the power OFF condition, the PC freezes at the BIOS message and will sit there forever .....................

If instead I press DELETE on bootup, it will boot right through to the BIOS settings page (blue/white screen) whereupon, I do the ESC and EXIT bit, get presented with "Start Windows Normally" and all is then OK.

If I do a reboot using the reset push button, it will only proceed to the BIOS part where the HARD DISC is checked and again will sit there for ever...........................

Now, to confuse it further, if I turn the PC OFF and ON using the front deck push button, it will do a normal reboot right through to starting Windows correctly.

Whilst the PC runs reasonably well thereafter, it is quite common for it to do a complete and total shutdown for no reason whatsoever or the keyboard or mouse to suddenly stop working.

On the back of the deck is yet another ON/OFF switch and using this to reboot the PC results in a normal bootup.

So something stinks using the RESET Pb on the front of the deck or a normal cold bootup.

I replaced the Motherboard battery, pushed and pulled all the wires - as you do - all to no avail.

It is far from a happy PC and I suspect either the power pack is playing up or the Motherboard is on the way out.

A:Power supply? Motherboard? OS? .... or what?

Sure. Start by going into the bios and checking your temps and voltages; specifically the cpu temp, system temp, 12V, 5V, and 3.3V values. Post those here.

Next download and run memtest This runs from bootable media ie CD, floppy, etc. You need to make the bootable disk and restart with the disk in the drive [CD set as first boot device in the bios]

Test the hard drive with the drive maker's diagnostic. You download this from whomever made the drive ie WD, Seagate, etc. Most of the time you have a choice between a windows version and a dos or boot version; get the boot version. Again it runs from bootable media.

One other thought; have you cleaned the system at all? If not, open the case and give it a good cleaning with a can of air [available at any office store, computer store, even walmart]

My computer recently had a failed fan in the power supply unit. I took the machine to an official computer tech company and they replaced it. I brought the machine home, used it once. I turned off the machine, unplugged it to use outlet for another computer.

I then replugged in the machine with the new power supply and nothing happened when i turned on the machine. Nothing, nada, zilch. No noise, no video, no nada. I see a green light on the chip board inside the unit so i know its receiving power, but no Action.

Is this my motherboard now, and maybe my processor. The tech's say that i need a new motherboard and processor. But i dont trust them anymore after my replaced power supply and now dead computer.

Any suggestions on the logic of what's happening with my machine? PLEASE HELP. I'm an end-user, not a tech...so I just need this all to make sense.

Thank you!
 

A:Power Supply or Motherboard?

Hello there and welcome to Techspot!

I feel your pain. We've all been there. Not that sympathy makes things any better, but you have mine.

It is hard for us to tell what is wrong with your system without looking at it of course. But maybe we can help you confirm a few things.

You say you can see the green LED light is lit up on your motherboard. That's a good thing. When you push the power button, no fans are spinning at all? Not a good thing.

It could be any number of things, and the tests that need to be done involve removing parts to help troubleshoot. Do you feel comfortable doing these types of things?

Try unplugging and reconnect your power supply connections to the motherboard.

I would also test your computer case's power-on button. This is done by disconnecting the small 2pin cable from your case that goes to your motherboard, then using a screwdriver to quickly touch the two pins that that cable was connecting to. This will short the pins, and hopefully start your computer. If it does, then your power switch on your case needs replacing.

Other than that, I would try this test to see if you can get the power supply fans spinning: http://modtown.co.uk/mt/article2.php?id=psumod

If the fans on the PSU don't spin, then you have (another) dead power supply.

If the fans on the PSU do spin, then we have narrowed you down to either a dead motherboard or a dead CPU (probably motherboard)

I would like to get it working as a secondary computer. Also, how can I tell what kind of power supply is required for that motherboard? Because I have tried a couple power supplies, and one was from a OLD 166mhz pc, while ther other was from a 866mhz, but it seems like the ends or where it plugs into the motherboard are different in shape. Any suggestions? This is a HP 900mhz pc, it would be nice for web browsing and other task. Thanks for any help!

Hi everyone,

First off thanks for any help in advance. I worked in tech support for 3 years and this problem is somewhat baffling to me. unfortunately, I don't have all the replacement parts I was used to working with or the test systems. So I am trying to figure out what is failing before taking 3 trips to the store buying and testing different parts.

so what happened...

First moved to new apartment, never had problems before that. within 10 minutes of turning computer (desktop), i was standing on the other side of the room, and system just turned off (didn't crash, just zap, no power). I didn't think anything at the time since i was still moving and messing with light switches and thought i randomly hit a cord or something.

a couple days later, after i had been using the computer for a while, games and all, one day i turn it one and it barely gets to the desktop and zap it turns off. First i think crash so i hit the power button to turn it on and nothing, no flicker no nothing. so i think power supply burnt up or MB fried. I curse in my head and go eat dinner. I come back after dinner and press the button for the heck of it and what do you know it works. worked all night, played games, cranked up the GPU. nothing no problems. i shut it down, check all the wiring in the back, everything looks solid. the entire 3 day weekend, worked great, lots of gaming.

This morning, turn it on to do some work, barely boots to desktop and zap, off again. press power butt... Read more

still won't boot up.. no PS running, nothing.
so i unhook the monitor.. then it will boot. all systems are go, but i can't do anything with it....cuz the monitor isn't hooked up. so i go to hook that up, and as soon as it touches the back of the case (and there is no static here) the box stops running.
completely. as soon as i move the cord for the monitor, its all good. it'll boot again.
so any ideas on wth is goin on with this?
no i do not have another monitor to test with it.. its xmas eve, and i doubt any of my frenz will think this an emergency to leave their familys over.

A:pc won't start - power supply failure?

Okay, this could be two things: the power-supply or the monitor, both of which you'll need to find another of, at least for testing purposes. If you get the power-supply then make sure it's the same type and make (look on your computer and give us the MODEL number for your specific computer, this'll give us the specs we need to determine what kind of power-supply you need). I don't think it has anything to do with your game, but it could very well have something to do with your graphics and/or your video card as well. Is it the power, or the dv15 pluggin (that's the plug where you hook it to the comp itself, NOT power, the other one) that messes it up?

Most likely this is a power-supply matter as you pointed out and that'll require a replacement. Those things cost alot, so if you can find a used computer at the dump or something or go to a local hospital and buy one for cheap, or have a friend with one they don't use cuz it's broke or something i'd do that, but make sure it's compatible!

God Bless and In Him,

My computer won't start up anymore...

The fan for the CPU comes on, but the rest of it won't (with the exception of the HDD and TURBO lights, which turn on but don't blink which reflects the sort of FROZEN mode it's in)... I dont' hear the HD boot... and it has been sporatically restarting itself all day (each time it reboots it seems to restart Sooner than before).... so it may be a short in a wire... I''m not sure.

The power supply seems to emit a hissing which after a few seconds dims or disappears.

I've checked all cables and they are in securely... no extreme things have happened to the computer, and before it went down it was SCANDISKed, DEFRAGed, and scanned for viruses (though I know for a fact it was clean)... it also has a firewall so it wasn't 'outside' interference.

A:Best Guess, Power Supply failure

Unplug everything from the power supply other than the motherboard and see if you get a picture. If so, plug in the floppy drive, then something else and so on.

If still no picture, try pulling all cards but video out.

Anything connected to the motherboard, when damaged, can cause what you are describing. Come to think of it, even a bad keyboard, mouse, or printer cable could do it.

I replaced the power supply and though "ahhh no biggie" Turned on the comp and what do you know, it still locks up. I have switched out every thing I can think of except for the CPU. It works fine as long as you are using it, but once you let it sit and it goes into a screen saver mode, It locks up. I have NO idea what could be the cause. Maybe the video card? CPU? Damaged when the power supply was going bad? HELP???

My "home-bilt" desktop running Win98SE has been hanging up on boot-up, so I decided to do an "over-the-top" reinstallation. I put my Win98SE CD in and rebooted, instead of loading the installation CD it booted up to the installed copy of Win98SE. This happened Twice ??

To check the boot sequence I went into BIOS and as I expected it was -
1) floppy
2) CD drive
3) hard drive

While I had BIOS open I noticed there was a line that read something like -
"CPU overheat protection" OR "Inoperative CPU fan protection"
followed by "Disabled" in RED letters, I changed it to "Armed"

BIG MISTAKE !!! -- If it ain't broke -- don't fix it !!!

When I rebooted, ALL THREE DRIVES [hard drive, CD-ROM & CD-RW] lite up like they were all trying to boot at once ???? After 5-6 seconds tower shut down.

After a couple of tries I moved the tower to the kitchen table and opened it up. I had a power cable BUT NO monitor. It went through the same 5 second shut-down, but I noticed the fans [CPU, AGP card & rear wall of case] were all running [for 5 seconds]

Then I looked into the power supply grille and noticed THAT FAN was running in "fits & starts". Using a pencil I noted the fan "spun freely" when the power was off.

I tried doing it again and again(for like what seemed like 50 times which... might of caused a future problem...) with different things unplugged and it still always did that. After all that I figured that the problem can be at least somewhat cured if I take out the big 20pin plug and put it straight back in and then it'll fully power up. But sometimes for some reason it goes straight back to powering for a split second and dieing. As long as I disconnect and connect the big power cord it'll power up, but that's not the problem I'm having NOW.

I recently decided to upgrade my computer big time by purchasing a new motherboard and processor and power supply/case. Anywho, it is a KD7-E motherboard, an AMD Athlon XP processor, and a 300watt power supply. The processor doesn't seem to be the problem though, so that shouldn't be anything to worry about. I put the new MB in to the case and hooked it all up correctly. I triple checked it a million times. It simply would not turn on at all until I hooked a friends power supply in to it, and that seemed to sort of jump start it. It came on, the fans and the lights, and it would seem to go just fine but then it would sort of hiccup and die. We hooked my power supply back in to it and it started working, but hiccuping just like the other. It would start up, fans and all, then they would just die all of a sudden. It seems that it runs longer though if you hold down the power button, for some reason. At first I just thought the power supply or the motherboard was fried, but that cannot be it, since they both work...just not well. I think it might be a short in the motherboard maybe? And it is not a lack of power either. It is a 300 watt power supply and that would be enough I believe. That, and my friends who we hooked in to it was a 450watt power supply, and that is more then enough.
