Computer problems - need bigger power supply?

Q: Computer problems - need bigger power supply?

I've had this computer for about a year and I've always had problems. I use to get blue screens when loading things that use a lot of memory. Now the computer will just freeze with blue screen and I have to reboot. It doesn't happen every time though.

For example, I'll be playing World of Warcraft which uses a lot of memory, I'll minimize and load iTunes. Sometimes it will freeze as it loads, sometimes it won't. Sometimes after it crashes and I reboot, I'll get a MACHINE_CHECK_EXCEPTION blue screen as windows loads. If I restart again, windows will load properly.

I have the case standard 420w power supply. I used a power supply calculator and it was a bit over 420w but I don't know how accurate those are. Heres what's in my computer using power:

Athlon 64 X2 Dual Core Processor 3800+
NVIDIA GeForce 7800 GT
1,024 MB Ram (512x2)
Realtek AC'97 sound card
Floppy drive
Two optical drives (DVD-ROM and CD/DVD RW)
One hard drive
3-4 fans total
4 usb
case lights

Preferred Solution: Computer problems - need bigger power supply?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

This one should work well with your board.


If you want to kick it up a notch for future upgrades choose this one.


If you want something a little less expensive, but good.

I have a 400watt power supply right now and have to replace my video card. Some cards i'm looking at say they require 400watt or higher. Is it bad to be running a video card with the bare minimum power? Would any other component suffer or should I be fine as long as the card doesn't require anything higher than 400watt?

A:Do I need bigger power supply?

PSU's degrade overtime, so you may have a 400W PSU, but what wattage actually it can supply to various components?

Also if you can tell which graphic card you are going to get, advising you about the suitability of current PSU or purchasing a new one will be much easier.

I'm undertaking the project of building myself a computer. All the parts I ordered came in the mail, and I was wondering if anybody would recommend upgrading to a bigger power supply. This is actually my first time building a computer, so I'm praying I get it right lol. If I do need a new power supply, is it difficult to install? Here's the hardware I've got

-Asus A8v Deluxe VIA Socket 939 ATX Motherboard
-AMD Athlon 64 3400+ Socket 939 CPU
-XFX GeForce FX 5200 Video Card (I plan on upgrading to a GeForce 6800 GT)
-Mad Dog Dominator DVD Burner 12x
-Speeze Socket 754/939 CPU Cooling Fan
-Ultra 512MB PC3200 DDR 400MHz Memory (I plan on adding memory, at least a gig, maybe 2... it's upgradable to 4 gigs but I think that's a bit overkill)
-Maxtor 120GB 5400 EIDE Hard Drive (I'm getting a faster harddrive, most likely 7200)
-Soyo Black ATX Mid-Tower Computer Case with a 350 watt power supply

I heard or read somewhere that with the 6800 gt they recommend a 450 watt power supply so that's why I'm wondering if I should go ahead and get it. Are there any performance advantages to having a bigger power supply?

Any other recommendations or suggestions? Any help would be appreciated

A:Do I need a bigger power supply?

350W is a bit lean for that system, you can't go wrong getting a more powerful one--even a 450W is pretty cheap, and it is the most important part of the computer.

hi, I am going to upgrade my graphic card to ATI 5770 so I need a new power supply which has power about 550--600 watt. But the most frustrating problem is that I failed to find a proper power supply with the correct dimension.
I have an HP pavilion e9300 which uses a very wired power supply tower-150mm(W) 86(H) 140(D). But so far all the PSUs I found is the standard size --150mm(W) 86(H) 150(D) which cannot fit in my setup.

So could any PC God give me some suggestion, please??
Is any PSU with the size of my tower or can I just simply install a bigger PSU which can still successfully power up the comptuer?

Thx in adance.

A:Power supply bigger than the tower - frustrated by HP PSU tower

If the power supply will physically fit your case, it should work fine with your computer. Will the extra 10mm interfere internally with anything inside the PC?

My computer died over the weekend. It was working fine before I left for work when I turn it off but when I returned home and was about to go to bed I heard a ticking like noise from the speakers, almost like a heart beat (power surging through the system?). The little lights on the wireless nic card and old modem card (no metal plates to shut the hole, so I left it in) were blinking. I unplugged it and was going to remove the modem in the morning thinking that was the problem.

Next morning I tried turning it on but it wouldn't boot at all. The PC started making some noise then turned off. I opened the case and looked inside, tried starting it again. The fans were ticking like it was getting power, turned off from the back and tried again. System started up again, then quit. Several times the system would either: Act like it was starting up but nothing displayed on the moniter with the fans running at full speed or run for a few seconds and die. I have plugged the system directly into the wall as well, thinking it might of been the power strip but get the same results.

Now that I think about it, it could also be the fan on the processor but that spins normaly. It normally would be loud as a rice burner going down the street at load up then quite down. I had that replaced about a year ago, guy said it could possible not be reset to the correct speed but since it gets quite after the whole boot process I don't have to worry about it unless I wanted to ...

A:Computer shut down - power supply problems? - fans start/shot off - not booting

Depends entirely on what the issue is. If the PSU is supplying power but not stably and the board isn't powering up because of that, you could be looking at just a PSU replacement, or various components.

What type of processor do you have? If it is an older model Athlon and the fan was not spinning fast enough, in theory it could have overheated and fried, though that is a rare occurence unless the fan outright stops spinning.

A:Do I need a "bigger" Power Supply

A 500 watt Antec should be more then enough for that setup. If you had a higher end video card that drew more power or a lot more drives then thats when you might want to consider a bigger PSU.

I'm currently a computing student so I rely on my computer a lot for my studies and was hoping I could get some quick advice/troubleshooting on here. So here goes :

I've had a problem with my computer recently, it's been working fine for a year or so with no problems, and then one day i tried switching it on and nothing happened. I tried once more and then the power short circuited (I then had to turn the power back on from the mains switch).

The strange thing is, my housemate had exactly the same problem, and after searching for the answer , he was told it was due to a static buildup and the solution was to take out components (graphics card, RAM) e.t.c and put them back in.

I tried this and no luck , I was thinking due to the short circuit, there may be a problem with a fuse in the power supply? other then that I'm completely stumped and would appreciate any help given.

Many Thanks for all help received

A:Computer won't power up (poss. power supply)

Does it happen with any other appliances? as in does using the toaster while using the kettle While your mate is in the Electric shower, telly on, or ironing?

Possibly a static build up, it is possible, Wher are you situated??
What voltage are you on?

What is the make and model of your comp? is it the same as your friends?

is your machine custom built or is it a brand?
Answer a few of them and we will try to narrow it down 4 you..

Mean while if you could get your hands on a spare PSU that would be handy. And remember when dealing with PSU's alway leave them to sischarge for at least 24hrs,
the 3 D'S, Disconect, discharge, dismantle.

My first post...

I received my new DVD DL +/-RW drive today and eagerly installed it. I of course unplugged my computer's power supply while doing it. After plugging the power back in, the green LED on the back of the CPU started blinking (never noticed this before), and when I hit the power button, NOTHING happen. No fan turns, no lights, nothing. When I unplug the power supply, the green LED blinking gets slower and slower, and after about 15 minutes it totally stops. I plug the power suppply back in and it starts blinking all over again and still the power won't turn on.

All I did was replace a CD-ROM drive with a DVD Multi drive. I didn't mess with anything else, so there should be no power supply shortage or problem. Any thoughts as to what could be happening?

By the way, I have a 2 year old Compaq computer with 2.0 ghz Athlon 64, 1 gig RAM, no problems thus far.

A:Computer won't power up after disconnecting power supply

While installing the new optical drive, you might have inadvertently loosened one or more connectors. Recheck all data and power cables to make sure they are tight, including all those to the motherboard.

First check if your pc is heating.get into your bios and post the temperatures and voltages

Check your PSU OR SMPS with a power supply tester.or manual testing if you know.there is another way but its doesnt fully decide well check it too
http://www.youtube.com/watch?v=WoIMkx6Uuzg&feature=related The video will explain you on how to do it. but i recommend testing using a multimeter or a powersupply tester which will be available for 8-10$ at the max.

I have AMD Duron 600, 160 MB RAM, 15 GB 7200 RPM HD (Pri Mas), 10 GB 5400 RPM HD (Pri Slv), 48x CD-Rom (Sec Mas), 4x4x32 CD-RW (Sec Slv), SB Live Value, GeForce 2 MX 32MB, and a 250 watt power suppy with Win98SE. I thinks that's all you will need to know. Now the problem.

I am having a lot of wierd freezes, games dumping that didnt dump on my old 233, and misc crashes that I suspect is because of my power supply. One particular problem is where I go to start up a program, lets say IE for example, though it does it to any program, and that program just hangs there for random amounts of time and then all of a sudden the program opens and all is well. Sometimes hitting ctrl-alt-del and closing open programs or just closing other programs with their regular exit makes the app im trying to open, accually open. Are there any software apps that can detect these types of problems? Any ways of finding out if my power supply is at fault or not powerful enough?

Another quick question. My 160 MB of Ram is a combo of a 128MB 133Mhz Dimm, + a 32MB 100Mhz Dimm. My bus speed is set to 100Mhz in cmos. Think any problems might come of this?
Thanks for your time.

A:Possible Power Supply Problems

Read other 7 answers

i tried to search through a bit and didnt find anything really specific to what my problem is, so here is my problem.

i recently bought a new computer (5months ago) and put everything together myself, everything has been fine and dandy until about a month after using it (alot), one of the fans on the power supply went out. so i went and bought a brand new power supply.

the power supply which i bought was an ANTEC 380W NEO-HE power supply. now i have everything hooked up right. but now i have been getting problems with hard drive crashes/errors/freezes.

im guessing its my powersupply or something. sometimes when i get a crash/freeze/error i will restart and it will say it cant access my hard drive or something and i will restart it again and it will boot just fine.
when i get errors in windows it will say something like 'hard error' and have an OK button and thats it. i will click ok and they will keep coming back 1 after another. they never stop, until i reboot.

my computer specs are

AMD 64 3800+

if u need anymore information plz ask.

and i will end my post with a big THANK YOU because i know you guys are the most awesome people i have come to encounter on the web in my 10+ years using the internet.

A:New power supply - Problems

Read other 14 answers

Hi all,

Just got this new power supply for the PC I'm building. The case and PSU have been the first things to arrive so I dotn have anything else yet. I bought the PSU (X-Power 700W) from eBay, the seller had a few of them and said they were all tested and fully working. I fitted the PSU into the case and tried to test it by connecting the two case fans and case LED lights to it. I switched it on and got nothing. Not even the fan on the PSU fired up. Does this straight away mean the PSU is faulty or could I be doing something wrong???


A:Problems with new power supply???

It wont

For the PSU to be activated just flipping the switch on the back will not do it. 2 pins on the big 20/24 pin molex have to be jumped. You can do this manually but i dont suggest it cause you can burn out your power supply if you jump the wrong pins. But if you must, google it and you can find a guide somplace im sure that shows you the right wires to jump. I know wich ones to jump but I am not going to tell you and be responsible for you ruining your PSU.

These pins are jumped when you connect the 20/24 pins to the motherboard and then the switch comes into place when you hook the front panal connectors of your case to the motherboard.

I'm building an Athlon system (Athlon 900, ECS K7S5A MB, 256 M SDRAM, ATI 32M video) and everything went pretty smoothly 'till I tried to power it up and nothing happened. No fan, no PS running, no nothing. I searched several posts on this and other forums and have tried the following:
- jumpered the power-on header on the MB
- checked all jumper settings and connections
- removed the board and PS from the case and tried to power it up that way
- tested voltages from the PS
- cleared the CMOS jumper.

None of these made any difference. The only possible problem appeared to be the PS. when I jumpered pin 14 to 15 it would run, as would the case fan which I had connected to it. However, when I checked the output voltages (both with the PS plugged into the MB and unplugged) the only pins that registered were
pins 14 (3.3 v) and pin 9 (5 v). Is this normal or not? Will the other pins only register a voltage once the system is powered up?
If the PS is ok, any other ideas on what it could be or other troubleshooting I could try?
Thanks in advance and merry xmas.

Definately not normal. There should also be a 12V source. Here's what should be there:

Hi, I bought a Toshiba L25 Satellite almost two years ago and it has been working great up until a few months ago when my adapter died on me. This problem was confirmed from a Best Buy computer technician using power testers. So after knowing that, I bought the Taurgus Universal adapter and worked for a little while but now it is going from Battery to Plug power all the time because the battery signal goes on and off the bottom of the screen every 10 seconds. Sometimes it will get worse when I want to use the DVD player and it has shut off many times because the battery got to low even thou it was plugged into a power outlit. I thought maybe it was the adapter so i bought a compatible Toshiba adapter but that only worked for two days until I started getting the same problem. Eventually, I could no longer use the new one and I had to switch back to the Taurgus adapter which charges my battery really slow. Also, this might be important...are all three lights supposed to be on all the time because my battery power/outlit light is not on. Can anyone tell me what the problem is? Is anyone else experiencing similar problems with their laptop? Is the problem most likely internal?

Okay I think it is a power supply problem.

My computer is 16 months old and I had a melt down with it before. A few months after I put it together, I had a problem with it. It was suggested it was a PSU issue, so I replaced it but it did not work, so I warranted/replaced the MOBO and still no luck, so I gave up and let it sit a while, I then tried another PSU and it worked fine since then.

Two nights ago I was doing a lot of transfering from one hard disk to another to backup some information, Swapping information from internal to external. I set a few large files to be transfered then went to sleep. In the morning I shut the computer down to remove my external HD. Even though the computer shutdown my power light on the external was still illuminated. So I used the power button on the Power supply to depower it.

Last night when I went to turn on my computer nothing happened. I pushed the power button and nothing. There is a green light on my MOBO but thats it. I am assuming/hoping it is the PSU.

Sonata II case
Asus A8N-SLI deluxe case
2GB ram in 4 sticks
2 internal HDs

Those will at times require 20 minutes to recycle so try it again later. I find it hard to believe Antec psu's are blowing like that though. I would wonder if there isn't a component there somewhere the system doesn't like, incompatible ram or something.

A friend of mine built a computer for me, and it was working fine until I tried to turn it on one day and it started to turn on, the lights and fans came on, but then it just shut off. When I tried to turn it on agian, it would do the same thing, the lights and fans would come on for about a second, then it would shut off.

So I got a new power supply, a 500w just in case the 400w was too low. It worked fine for about two days until all of the sudden the screen goes dead. So in the midst of trying to figure out why I'm not getting any picture (trying different monitors and so forth), I try to turn the computer on and it does the same thing it did with the last power supply.

In case it matters the first power supply was a PowerMax 400w.
The second was a Power Magic 500w.
The video card is a Gforce ti 4200
512 ram
1.6 ghz.

Ok. Here's the problem: First of all, I have a Compaq Presario X1000. My mother borrowed my laptop, well when i got it back it wouldn't turn on. So I went out and bought a power cord (universal cord), they said it would work for my computer. Ok, i also bought a utility fix it disc (maybe just a coincidence) but when i used it to fix the registry keys the laptop quit charging while its on, but it will charge while its off. Alright when i finally figured out that it stopped charging around the same time i used the utility disc, i went back and undid what i did with the utility disc except one thing that it wouldn't undo. Well, now when you turn the computer on if it has a low battery it will charge while its on but when the battery gets full it quits charging. If you go to power options it says its running on AC power but the battery is still going down. Also, if the battery is low and you try to turn it on you have to push the power button in and hold it for a long time before it will finally come on. I was thinking it probably needs a new battery, but wouldn't you still beable to stay on the computer if its using the power cord? Because when the battery gets low it just cuts it self off. PLEASE HELP! I AM SO CONFUSED!

I've been having trouble with my desktop PC. There had been problems with two hard drives dying, as well as what I believe may be power supply issues. Before my past hard drive died, there were boot up problems; sometimes the computer would beep when turned on (nothing would come on the screen), sometimes it would come on very loud, with the fan running very high (again nothing would come on the screen) and sometimes it would boot all the way up until I got onto Windows, but an accidental bump of the desk or something of that nature would cause the computer to freeze, with the screen going into an odd checkered glitchy pattern of whatever was on the screen at the time. This was sometimes temporarily fixed by pulling out and putting the power cord back in (hence my theory of the power supply problem).
My friend recently installed a new hard drive and Windows Vista for me, and it seemed to be working okay at first, but then some of the problems I think might be power-associated soon re-emerged. I got that glitchy, checkerboard screen randomly without any kind of jarring, and I occasionally get beeping on start up. Also, when the computer goes into screensaver/sleep mode, it will not come back on and you have to restart it.
Does this sound like a power supply problem? If so, does it sound internal or possibly like a problem with the electrical socket in my house? Can anyone help me out with what to do here?

Thank you,

It is possible that it is a pw supply. To test, swap in a known good pw supply. If it works, great. If not, then I would replace the mb.

FWIW, I would put my money on a failing board in this case. This what makes me think mb rather than pw supply

I haven't had any problems with my computer and it has been running like a champ. It's about 3 years old and yesterday I was using my computer and both my monitors (dual screen setup) went black but my computer was still running. I could hear the fans working and all the LED lights inside of my computer case were still working, but I could smell that something was burning. I turned off the computer for a couple minutes, then back on. The computer turned on, and my monitors stayed black. The smoke smell got stronger, so I ended up replacing my power supply and my computer works again. . . kinda.
It took maybe 10-15mins for my computer to boot up, then when it booted up, I reset it to see if it would re-load any faster and my monitors stayed black and still no picture. I turned off the PC and turned it back on, and after about 10 mins of loading, it worked fine.

Here are my specs:

A:Problems after Power Supply went out

Read other 13 answers

Ok, so I have no real idea what my problem is, but after reading some forums, and stuff, I'm kinda leaning towards my PSU being the problem. So, when I play a game, after a couple of minutes, my pc will just randomly shut down, and refuses to switch on, for at least a couple of minutes. At first I thought, this is an overheating issue, but as I played, i kept an eye on my CPU and graphics card temps, and they both stayed in the norm of about 58-63 degrees, when under stress. so that ruled that out. Next I thought, as now and then the computer would start up when I pulled it out and inserted it again, that the lithium battery keeping the PC's time was causing problems, but that didn't a;ways work. So lastly I read that this could be a sign that a PSU is packing up, or that it's cables are creating a short, resulting in the loss of power, which in one case I pulled the wires out of their confines(cluttered and stuffed together in the case) and the PC came back on. I honestly don't really know for sure what could be causing this, and thought I'd seek out some council. Any one have any advice?

Edit: I should add , that the shutdown has happened randomly, the other day it happened twice in a row, I fiddled around with the pc, and was playing fine afterwards , until today when it started again. Happened 3, 4 times again, pulled the PSU cables free, and was playing recently with no problem.

A:Possible Power supply problems.

Does this only happen in one game that you know of, or every game that you play? It's never happened outside of a game?

Are you overclocking at all?

Unfortunately the best way to troubleshoot if it's a PSU issue is to get another one and try it out.

I have a Toshiba Satellite 1400 series laptop running Win XP home edition. 40 gig HD (70% full), 512 MB ram.


The machine one day refused to boot up. I noticed that even when plugged in the general power light on the front of the case did not turn on, so I assumed it was a power supply issue. Perhaps the battery was dead? I borrowed the girlfriend's battery (we have the exact same model of laptop) slapped it in and my machine booted right up. So, I assumed that the Li-Ion battery was somehow required for boot, even if the laptop is plugged in. But, once the laptop booted I swapped out her battery for mine and it still ran, but it would not run off of the battery alone for more than a few seconds. So I ordered a new (and expensive) replacement battery.

Now, running on the new battery I notice that it still doesn't charge, the battery power light (different from the general power light) on the case never lights up regardless of what power source you're using. I also notice that the battery power icon in the systray is gone - you know, the one that tells you if you're running off the battery or a wall socket and how much battery life is left.

This leaves me conflicted in my troubleshooting. The fact that the light on the case doesn't light up indicates a hardware failure. However, the missing icon in the systray leads me to some messed up operating system glitch.

What do you think?

A:Power supply problems

If you use your girlfriend's power supply, does it still have the same problem of not lighting up or charging? If so, your power adapter has probably died.

I own a Dell Optiplex 745, minitower, and I do not understand what my problem is. It has a standard, 350 watt power supply with a 24 pin connector and I tried to replace it with a new ATX 750 watt power supply with the same 24 pin connector. I plugged in everything properly (I triple checked) and every time I try to start the computer, the Dell loading screen pops up as usual, but it stops loading and the computer makes a rapid beeping sound and stays like that (with the loading screen frozen and computer beeping) till you turn it off. Is there a way for me to tell if the power supply is bad or if it's not compatible with my computer..?

I just put a new power supply in my computer because the old one wasn't getting it done. I got a 500w ultra w/ x-connect. When I turn on the computer it powers up for a split second and then turns off. When you press the power button again it does nothing. If I turn off the power supply on the back of the computer, then wait a few seconds and turn it back on it will do the same thing. Is this a problem with the power supply, the installation or what? Thanks!

A:Power Supply problems

Good Evening Blake05, this kind of behaviour is often referred colloqually to as a "Lie down and die" kind of system.
Most often these kinds of systems have a sensing ability where current is monitored against time as the machine functions, the object is to sense a short circuit and remove power before the system can be badly damaged.
Most often these kinds of systems need to have power removed to allow the system to reset before power is once again available.
Actually it is a good idea, but there are occasions where it can be a headache if the triggering is oversensitive.

This problem is hard to troubleshoot but it is quite likely that something in your machine is drawing current a little too heavily more quickly and that the triggering could well be real.

It would be easiest to disconnect all the power plugs to items apart from the motherboard, disconnect the IDE's and other cables also so that nothing is damaged.
Now try the power on with just the motherboard connected (and the processor, memory and other standard needed basic items)
If the problem remains there is either something wrong with your PSU or the motherboard, processor, memory and video system.

If all is well you can proceed coaxing each item into life untill you determine what may be the problem. It may well be a drive or something other.

Most often with these problems I have found the problem was not the PSU.

Nothing is ever as it seems.

Cheers, qldit.

OK i have a Pentium 4 motherbopard with no power supply but i also have a pentium 3 power supply. My question is even though the pentium 4 board has a Pentium 4 power suppy spot in addition to its regular power port, do you have to have a Pentium 4 POwer supply or can you just plug in the main power and not plug anything into the pentium 4 (power supply information feedback) port. will the motherboard still work.

Hi. A few weeks ago I installed a new power supply into my computer. At first, the computer was working fine. Now, when I try to turn it on, I get no response or I get a blinking yellow light. I think it could have something to do with the large amount of unnecessary cables in the power supply, but i'm not sure.

A:New Power supply problems

I wouldn't believe the extra wiring would have anything to do with your problem if it was routed and stored correctly.

If you don't have a power supply tester, I would take it into a shop that has a tester and let them test the power supply. It only takes 10 minutes or so, and the cost should be nominal.

I have an amd 2000+ asus a7s333 mobo .. 3 case fans (2 intake 1 exaust) 1 cpu with heatsink and fan , all of them are working properly

yesturday i was working on a webpage and then my computer shutoff automaticly, cpu was @ 170F (i noticed that the power supply was exausting alot of heat)

i opened the computer and clean every parts with a F#$% Q-tip (inside the power supply, fans etc) I left the power supply on all night (using the green and grey wire.the power supply was not connected to anything) this morning the power supply was working properly and did not produce any heat.

after cleaning the cpu and heatsink I added thermal grease and plugged everything back into the computer. push the on button..after 60 seconds my cpu was already @ 55C

i checked the cpu fan (air was cold) checked the power supply fan (air was hot) theres a fan in the power supply that pushes the air into my computer directly on the cpu. could the sensors read the air from the power supply and give me false reading? is it normal for a powersupply to produce that much heat?

my computer is @ least 4-5 years old.. what should I do?! please help !

A:Heat problems or power supply?

Hello and welcome to techspot!

55c idle is a little toasty, but may not critical for your CPU. What core is it? Is it the T-bred? If so, the max critical temp for that particular CPU is 90c.

But to a different issue, are you SURE you PSU is blowing are INTO your case? It should be blowing air OUT.

A computer I'm fixing causing me a headache.
It is connected to a hardware switch for the screen and keyboard / mouse.
It will randomly turn itself off and restart by itself after a certain period of time, or if you switch back to that pc using the switch it will seem to trip out and restart. It then fails to restart for a while and then will do it about 10 minuetes later.

The PC was FULL of dust and the PSU too, I have cleaned that out but it still keeps happening.

I think i have narrowed it down to the Power Supply, in the fact that it happens when you switch over to it and it has more strain on it from the graphics card.
I don't really know what else it could be..
Is there anyway I can find out for definate without replacing it with a new one?

The PC is about 3 years old.

Many thanks

I started having power supply problems a couple months ago..my laptop shuts off when I run a program extensively..for example: Norton Antivirus. I'm gonna be getting the power supply fixed soon. But...I started having modem problems a couple weeks ago..It will take over an hour to even establish a "half way decent" connection. My connection just sits there, doesn't disconnect me..but simply doesn't work. So then I find out its my modem. (Computer will freeze when disconnected)Which didn't really bother me, as we are getting cable next week. BUT. I'm worried that maybe the power supply has caused these problems, and that my cable modem might not work. Any advice/thoughts about this? I just don't wanna get the cable modem and then have the same problem. But I'm hoping that it will cure the solution.

I have replaced a 200W AT power supply with a 250W ATX power supply. When I turn the ATX power supply on all I get is the power on LED, no other devices fire up including the fan in the p/s itself. Can anyone suggest what might be causing this. BTW this is the second ATX p/s I have used.


A:{SOLVED} ATX Power Supply problems

Probably because atx uses soft on and at doesn't. The power supply is waiting for the soft on signal from the motherboard. But being it is an at motherboard it isn't going to happen.

I got a new UPS (uninteruptable power supply) for christmas and when I hookded it up it worked fine. I got to reading the instruction book and it said to buy a serial cable and hook the UPS to your computer. This tells you what the status of your UPS is. When I do that the UPS shutsdown and won't start up again.
