PC Won't Post or Boot

Q: PC Won't Post or Boot

When I press the power button, fans start then immediately stop, then start again, etc. Disconnected all peripherals but monitor, removed memory stick. No signal to monitor. When connected, hard drive starts then stops in time with the fans. It seems the PS is cycling on and off continuously.

Preferred Solution: PC Won't Post or Boot

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.)


I am having the one of the worst pc problem i have faced.....
It all started with my pc restarting(it was a power failure) to show boot device failure, insert system disk, i tried everything, from unplugging usb devices to re inserting sata cables but to no avail, now when i try to reinstall windows the setup recognizes all my partitions but refuses to install into any of them, ubuntu only recognizes one of my hard disk and partition( i have 1 big 500 g hdd as 1 part, and 2 250 g hdds in raid 0). I tried booting from my bart pe created windows live cds but they dont detect any partitions what so ever, windows 7 dvd's repair utility can access my file structure when i browse for drivers, but it wont repair the problem, nor will it install.
Please Help!

I am having problems with direct booting into Windows 8 installed into a VHDX file.
This is a four-partition UEFI boot on a GPT drive. EFI files are residing on a second partition of disk 0 (the ESP partition) in the EFI folder. The boot virtual disk is residing on the fourth partition of that disk 0.
When I turn on the PC, it shows black screen after the BIOS POST screen. No Windows 8 boot menu, no other information is displayed. However, if I press Shift+F12 (or F12) to start Dell BIOS Boot Menu and choose Windows Boot Manager from the UEFI part of
the boot menu, Windows 8 starts to boot without difficulties.
How do I make Windows to boot automatically without having to select Windows Boot Manager in DELL BIOS boot menu?
I believe I messed up with boot sector somehow... What needs to be fixed provided that Windows 8 will boot into VHDX file?
Thank you.

Well this is the world we live in And these are the hands we're given...

Sorry first time poster. I wasn't too sure whether to post to the Windows forums or hardware forums. From what I can see, this seems like a hardware issue of some sort.

The problem I have is that during bootup my PC goes through all the normal things. It detects my CPU, detects RAM etc. gives me nice BIOS Post messages that appear normal and then goes to a black screen. It will then sit there for 50 seconds (i've timed this twice) and then proceed to go to the windows XP startup screen (which takes about another 10-20 seconds to load up windows).

I've attempted to log the bootups by using the Windows Boot logger (by pressing F8 before windows boots). The ntbtlog.txt file isn't very descriptive, and only lists that a whole lot of drivers have been loaded, and some that haven't (it doesn't list any errors).

I've also tried using BootVis to analyse the bootup. I found this a little hard to decode the information it gave me, but there doesn't seem to be anything untoward happening.
The last boot logger I tried was bootLog XP (by greatis software). According to bootlog XP, windows is only taking 19 seconds to load up.

Can anyone suggest any other ways to analyse the boot sequence and discover where my computer is stalling?

(specs are below.)

Thanks in advance,

I just got an MSI K8N Neo4 S939 mobo with an AMD Athon64 4000+.
Put it together with my previously owned PC parts and it won't start. The hard drives don't spin, nothing but the CPU fan. I took all the accessories out (drives, cards, ram). And still the same. The monitor doesn't get a signal.
Also, maybe important... when I turn on the PSU, the CPU fan turns on. I have to press and hold the case power switch for a short time to get the "system" (fan) to turn off.

A:My will not boot/post/do anything at all...

Your system is DOA (bad mainboard).  If you purchased direct from Dell, you can return it for replacement within 21 days after it shipped to you.  Call Dell to start that process (DO NOT depend on email or chat).  
If you purchased through a retailer or independent third party, contact them for replacement of the system.

I am having trouble with a system running WinXP Pro. It has an Asus mobo, AMD 2500 CPU, 512MB DDR 400 RAM, an FX5500 video card, separate DVD and CD burners, and an 80G Western Digital HD. Everything has been running well for the most part for almost a year. Now I cannot get the system to even post.

When the power switch is turned on, the CPU fan goes on briefly and then stops. Nothing else happens after that. The green light on the motherboard goes on and stays on. The case wires are connected properly. I tried swapping power supplies but that made no difference. I then swapped the RAM, and got nothing, then changed the motherboard. When I powered up after replacing the motherboard, the CPU fan remained on for about 8-10 seconds longer, but other than that there were no changes. If I clear the CMOS and then try to boot/post, the CPU fan stays on for a good 15-20 seconds, and then when I hit the power button again I get nothing, unless I clear the CMOS. It still will not post though.

Could the CPU be causing this kind of activity (or absence of it)? I don't have another CPU to swap out and I don't want to go buy another one unless I am certain that could be the problem.

Any insight and help on this would be greatly appreciated.

I've got an old HP Pavilion 4455 that I got from work for my kids to use. It's 400 Mhz, win98se, 192MB ram. Was running perfectly fine one evening. Shut it down that night, turned it on the next day, and it won't boot. No post, no beeping of any kind. Everything 'appears' to power up. Hard drive is starting, processor fan is going, cd rom light comes on, and I can open the cd rom, and the fan in the power supply is running. Can't boot from a floppy, as it seems to not get to that point in the boot sequence. I have noticed that while everything does seem to be getting power, the floppy light does not come on at all.
I downloaded the pdf for the motherboard in this machine, so I could try re-setting the bios. But, the really strange thing is that where the diagram says it is, there isn't anything in that location on this board. So, I took the battery out for 20 minutes, and then replaced it with a new one. Same thing happens.
Anyone have any more thoughts or is the machine just dead?? (and good for minimal parts)

I just recently picked up a used XPS 630 which has been running fine up until recently. About two weeks after I got it it had a random hard drive crash which turned out to be a SMART failure having something to do with the read head in the HD going bad. I replaced the defective hard drive with a brand new Dell unit, performed a system restore from the image on the replacement HD and then installed Windows 7. Over the next two days I loaded the PC back up with all the stuff that I lost due to the bad HD (thank god for back-ups). Then, randomly, I try to switch on the computer and it won't POST. 
When I hit the power button the LED's come on, the power button is illuminated, and I can hear the case and video card fans spin up, but I nothing happens on either monitor. Is my MB or video card toast?
Any and all advice is welcome. The PC still has almost 2 years of warranty through Dell, but I'd much rather try and fix this myself first since calling tech support isn't the world most fun thing to do.
Also, all drivers, BIOS and firmware has been updated from Dell's site with the exception of the ATI drivers which are from ATI. 
System specs listed below....
XPS 630, 650i SLI MB, Core 2 E8500 @ 3.16 GHz, 4 GB RAM PC2-6400, Radeon 5850 HD graphics card, 750 GB Seagate Primary Drive, 160 GB Seagate backup drive, Sound Blaster X-Fi sound card, Ralink Wireless G PCI card.

A:XPS 630 will not Boot/POST

More info...
Power supply LED is solid green.
Attempted to unplug the unit and hold the power button for 30 seconds to drain any left over power...plugged it back in, same result. No POST.
I can hear the hard drive initialize, and the DVD-ROM spin up in addition to all the fans and lights coming on. 
I'm thoroughly stumped...

Hi all

I recently built a gaming rig and collected it yesterday. However, I have problems getting my rig to POST. Whenever I hit the power button, many times it would just hang there without any POST aka "beep" sound.

Only after numerous attempts turning on and off the power switch can I finally get the comp to POST and then boot up the OS.

Any suggestions would be greatly appreciated.

I've been having a few different problems with my computer recently. Having 3 different problems at once has made it hard to deduce the source of my major problem, being the computer no longer booting. First off, I've had some adware problems, which I dont beleive is related to my problem at all. Secondly, some textures in World of Warcraft have been displaying funny.But it didn't seem it was only the textures, whole portions of the User Interface where displaying funny. At first I thought the game files were corrupt, so I error checked game files and it found no errors.

So later that night I had to restart my computer after installing some anti-adware software to get rid of my "windowsclick" problem, and the computer would turn back on after the restart but wouldnt post or display anything to monitor. Similar to a recent problem I've had when I fried my vid card. Since I didn't have a spare vid card I checked to see if a RAM module was bad since I was getting these weird random computer restarts recently. After messing around with the ram switching out sticks in different sockets the computer actually started back up.

Thinking things were "normal" again I reinstalled my favorite video game to find the graphics doing the exact same thing as before. So I decided to try reinstalling video drivers. After installing the ATI 3600 driver from the site it required a restart. Upon restarting the omputer it did the exact same thing as bef... Read more

Hello all,
Maybe someone could help me with a problem that I am having.
I am running a Tbird 700 on a Epox EP-8KTA motherboard w/ VIA KT133 AGPset. I have 256mb of ram and a 15 gig hd and an ATI EXPERT2000 AGP 32mb video card. I was playing Pool of Radiance for a few hours and then saved and stopped. About 5 and 1/2 hours later, I checked the weather online (dsl) and then closed everything down to the desktop. Which is where I usually leave the computer, running with only windows desktop up and no programs running. Roughly 1 hour later I came back to the desktop to find that it had hung about a 1/2 earlier (the clock was stuck at the hang time). I tried to reset and nothing. I tried turning off the computer at the switch in the back and nothing.
I tried:
-switching out the ram
-disconnecting everything but the ram, hd, floppy, video card
-disconnecting everything but the ram, hd, video card
-reseating everything
-clearing the CMOS
-including doing it by removing the CMOS battery
and none of these things worked in rebooting the computer.
With everything connected I can turn it on and the cpu fan starts and the cdrw led pops on and then off, the cdrom led stays on,
the hd led stays on, the floppy doesn't run at all, the monitor sits in standby mode with its led flashing, and the computer won't even post. I would normally start to try and figure out if I burned something out, but this has happened two other times. Both times I shipped my computer back to the supplier a... Read more

Hi rowayn

Try disconnecting everything but the ram, video card, memory, and CPU and see if you can get the POST showing up on the CRT. If so you can add the removed items back one by one.

Are the hard drive and cdrom on the same cable? The lights shouldn't be staying on.

I have a system that will not post upon boot-up? The system was functioning fine and one day I tried to boot and nothing!! I hear the hard drive spinning and all of the lights are operating, but no image on the monitor?? I have removed the hard drive and memory and placed into a like system and each seem to be working fine. I also ordered a new motherboard (thinking that the board may be bad) and still no post (Beep) upon boot?? I have changed the jumper setting on JBAT1 to clear the CMOS and returned it to the "save settings" position (pins 1 & 2). I have also cleared the CMOS setting by removing and replacing the battery on the board. I have verified that all of the hardware is supported (and it worked fine for months).

I am visiting my Father. We are trying to upgrade the GPU in his HP Pavillion running Windows 7.


The PC was shipped originally with a Radeon HD 6450 (1 GB) GPU. It has only 2 video outputs and he wanted to add a third monitor. I recommended he purchase a new GPU. He bought a XFX R7 260X.


We also went to Fry's electronics and bought a new power supply, a Lepa N500, which is a 500w power supply. We have successfully installed the new power supply.

Now when I removed the old GPU, and put in the new GPU, the PC will turn on, the red led light in the front will turn on and stay red, but the PC will not boot. The screen is black, and it is not booting up.

I did one time forget to plug in the power to the GPU. That time the PC did start booting up, & I was able to use logmein to remote into it to turn it off, but once the machine was off again and I plugged in the PCIexpress 6 pin power to the card, same behavior. PC is out of warranty w/ HP, so they are no help.

I went to HP's website and updated the BIOS. still no luck.

We have added third party RAM. I tried removing the third party RAM to see if that was the issue. Didn't fix it. I tried removing the OEM ram and installing just the 3rd party RAM, but that didn't make a difference either.

Are you using that computer right now? If so, I might want to check some BIOS upgrades. Try to identify your Motherboard, get to the companies site, locate your motherboard, and look for a BIOS update. That might resolve it.

It takes me roughly 4 to 5 hours, start to finish, to assemble a new PC and load the OS. I lost count of how many systems I've built over the years, but this one has me stumped, I've never seen anything like it!! I hope there's someone out there that can shed some light into what's going on....
I started out with:
Intel LGA775 ATX Motherboard BLKDP965LTCK (D41694),
Intel Core 2 Duo E4600 LGA 775 Processor,
Zalman Ultra Quiet CPU Cooler,
Mushkin 4GB (2X2GB) DDR2 Memory,
Logisys All Clear 550W ATX Power Supply (With UV Cable Management sleeves),
eVGA GeForce 9600GT Superclocked 512MB GDDR3 PCIe 2.0 Video Card,

and I added an AVerMedia AVerTVHD MCE A180 PCI ATSC HDTV Card,
HP w2207h Monitor,
Creative SoundBlaster Audigy SE 5.1 Channel PCI Sound Card.
I packed it all into an Blue Apevia Aspire X-Plorer ATX Mid Tower Case with enough mods to light up the whole house with a bright blue glow.

A:New PC will not post or boot, $1,800 Nightlight

Go back to basics. Is it plugged in? Thermal paste? bad case, bad case switch, bad cable. We have seen this at least three times due to bad case pins, switches, or cables. It has to be there, right? You have a fundamental failure that you would not normally expect. Check your electrical box to see if one of the switches has been thrown open. Verified adequate electrical power at the socket. Do you have a volt ohm meter?
Test everything from that basic level.
Then, leave it alone for 24 hours. Get some rest. then when your frustration level is down and your sense of humor is back, get to work.
I would start out with the most basic system. Motherboard, CPU, thermal paste very thin, one memory module, and any bootable device... preferably a USB floppy drive or a simple optical drive.
Does it boot?
Keep adding components one at a time starting with additional memory... until you have tested each device one at a time, removing other stuff util you create a history for each component.

This issue only just started about a week ago. This only happens when I first boot up my ASUS K73SV laptop, it will run fine for about five minutes, but then it will gradually start to lock everything up, to where whatever programs I was using stop responding, then the taskbar is the next to go, and then anything else. The only thing I can do is move my cursor around as the blue wheel spins, and wait precisely five minutes until everything starts back up again. I was going to try a system restore, but the access points do not go far enough back. My computer is very frequently cleaned with CCLeaner, and I have avast! to help make sure nothing is infecting me. I've made sure I have no suspicious programs installed and everything. I am at a loss. I do not know what else is left to do.
After Budapest was unable to help me in my topic "Locking Up Issue", they referred me to this area to follow the instructions and make a post with my DDS log. Here it is as so.

Hi Everyone,

Bit of a toughy here but hope you can help me out.

Went to turn my computer on this morning, everything seemed fine as I had been using it for hours the night before. Anyway what happened was the computer sounded like it turned on ok, but the screen wasn't working. The screen was in 'stand by' mode as in there was power to it but no actual signal.

So tried another, screen - same thing happened. Tried both these screens on different computers and they worked fine.

So did some research about computers and booting and came across the term 'POST'. From what I understand ALL computers will make a small beep when they boot which is known as POSTing - a basic indication that the boot sequence was successful or not.

My computer is not making any sounds or beeps on start-up. The floppy disk and CD drive will spin and light up but no beeps. So the question I beckon is:

1) Do ALL computers definitely POST (beep upon successful Boot)?
2) If your computer is not POSTing, where to then? I think it's a matter of replacing the motherboard.
3) Is DIY replacing a motherboard a big thing? If I can source the exact same motherboard and just to a simple switch - will that be ok?

Thanks everyone - any comments very appreciated.

Sony Vaio desktop, 2005, has boot hang-up, and after slowly going
through the obvious, my question is if there is something I'm missing?

Boot stops at manufacturer's and Pentium 4 logo after making one beep and message "Input 2: HP15. No drives recognized, so nothing with recovery disks. No keyboard shortcut to Bios. I've attempted:

1) replace power supply,
2) reseat memory chip after rest,
3) reseated RAM sticks and MB plug,
4) removed exterior plugs, was able to transfer some files from the HD to another computer.

Any suggestions for me at this point? I don't know what else to look
at except CPU/fan and the MB. Can always freeze and retry my HD, I guess. bookburn

Hi, and welcome to TSF.

Do you have another monitor you can try?

I'm trying to update a friend's computer cheaply. I've purchased the following parts:

MB: Soyo 7VBA133U
CPU: Intel Celeron 1.3 GHz (Tualitin Core)
G Card: Asus X Series V9400 (nVidia MX 4000 GPU)
HD: Western Digital WD400 40 GB
RAM: Generic PC133 256 MB

The system doesn't need to be screaming; she only uses it for light home use (i.e. some pictures, mostly music).

When I try to boot it, the system starts the posts but hangs on post code D3 (Phoenix Amibios). 1 out of 50 reboots will be successful and load Windows.

How do I get the system to boot everytime?

A:PC Won't Boot / Post Problems


Is this a fresh install of (windows?)?
I would strip the sys down to bare:
if not then switch out each item until succeful.
When successful I would clear cmos.
Then add HDD.
Then setup bios as desired.
Then do fresh install
Then add devices (sound, lan, cdrom etc.) one at a time.
Not everyone will agree with me but you need some form of
fact finding without too many devices all at once.

I have been through 3 different motherboards and 3 types of ram and computer will power on but will not boot on all 3 motherboards. I tried booting without the videocard and still just powers on and sits there. Then I tried it with out the video card and ram, same. Then finally I booted the motherboard by itself with nothing attached and got the same thing just powers on and sits there. Can it be the power supply or cpu? or am I just having bad luck with motherboards?
Here are the boards I've tried.

Hello, please help. My Gateway GT5056 p.c. began to act strange, got worse and now may be dead. All of what I describe below happened over a period of a couple of weeks.

I first noticed a lot of HD activity when the computer was idle, that appeared to be the system idle process.

Then I got the following blue screen error message.
Stop: 0x0000009c (0x00000004, 0x8054D5f0, 0xb2000000, 0x00070f0f)
Beginning dump of physical memory.

I was able to hard restart, then I had two separate occasions that the monitor display would go hay wire (similar to the old t.v. sets where the vertical or horizontal control was out of whack) no error message with those occurrences. I was still able to hard restart.

Then I got the same blue screen message as above. The difference now is that it will not POST or boot up at all. All I get is black screen.

The HD and the monitor test fine in another p.c. I have tried it with one ram chip and no ram chip. I have unplugged (one at a time) and tested with everything that could be unplugged. The Gateway does not have a separate video card.

Any suggestions on how to troubleshoot this will be highly appreciated.

I have win xp home with 256 worth of memory.

my problem is that for some reason it boots very slow to post, what happens is when i turn on the pc it seems to sit there for a few minutes, then i can hear the network card make clicking sounds for about another 30 seconds or so then the hard drive kicks in and things boot fine. no problems with windows or booting after that.

It only seems to happen when i boot after the pc is down for a while.

the thing is is that I have win xp home on two machines,both networked, and both have visiontek xtasy 9200 cards in them,same config on both machines, but the first takes forever to boot to post and the second boots with no trouble at all.

I have ran both spybot (updated ) and adaware (updated) which cleaned out things, cleaned things up with the disk utility tools so forth and so on.

anybody have any ideas as to what can be causing this?

I'm trying to help a friend with a PC problem. Here's the specs: Windows 98, Microstar MS-6368 Socket 370 w/ PIII 866, on-board video & sound, 10 gig HDD, CD, CDRW, FDD, 56K PCI, 1 stick of 256MB PC133, etc.

When I press the power switch, everything (HDD, PS, CPU fan, etc) turns on but there's no video, no post beep, and no memory test. But if I wait long enough (literally 3-5 minutes) the PC will beep and post the initial boot screen then everything is fine form there.

Here's what I've done so far...
1) I stripped the machine of everything not needed and it still had the same problems. I left only the CPU, HDD, memory, on-board video and sound connected (no FDD, no Cd drives, and no 56K PCI modem).
2) Swapped HDDs, no change.
3) Swapped memory, no change.
4) Swapped IDE cables, no change.
5) Virus scan came back clean running the HDD on my PC as a slave drive.
6) I tried another PCI video card (but I didn't disable the on-board video if that matters any).
7) I reseated everything, literally everything (power supply connector, CPU, memory, all cables, etc).
8) I swapped power supplies, still no luck.
9) I reset the CMOS jumper, no change.
10) I replaced the CMOS battery, no change.
11) Tried different power cord, no change.
12) I have this plugged into my monitor, keyboard & mouse and no changes either (same problem as when system is using my friends monitor, keyboard & mouse).
13) I've also tried another pow... Read more

One thing you didn't try is flashing the bios.

I would tend to believe that the motherboard is at fault, but it only takes a few minutes to flash the bios

hey to everyone out there..lol I'm working on my dad's friend's computer. They said it was having some problems (i got the famous "It's broken" and the famous "It's too slow") But the PC wont even post/boot. When i turn it i get 1 long beep, and then 2 short beeps, and then one weird sounding beep. I think it might be the vid/graphics card because nothing shows up on the monitor. then again, it might be memory. If anyone can help out, it would be appreciated, thanx.

My computer will not boot at all. the power supply works as do the cpu fan and video card fan, but it seems that the HD do not start up. tried a floppy but nothing. the computer does not even go to post, just a blank screen. monitor has a self test that confirm it is ok and to check cables etc but they are fine. checked that the video was in properly and the ram was seated correctly
The dvd drive has power and will open/close.

It all started after a power surge blew out the power supply, replaced that and the power not got to the MB but this problem then started. Replaced the MB as I thought that might be the problem. now using a brand new A7V333
I have 512mb 2100 ram (2x256) GEForce 2 AGP

Thanks for any help or ideas

Hi John! Welcome to TSG!

I'm no pro with hardware but this sounds like a CPU problem. Can you test it or try another?

I'm at my wit's end and hoping you all can help me. It's an older computer that I need and can't replace at this time because we are financially strapped due to unfortunate circumstances. I have a Dell Inspiron 570 that started having issues a couple of weeks ago. I thought it was the monitor because everything went black. Switched out the monitor and it worked fine for a week. Then nothing. All fans are working. It seems like the computer wants to POST but it's not. You will see a flicker on the screen and then nothing. No words will come across the screen. No beeps other than when I remove all RAM (stating it has no RAM). I've looked all over and now hope you all can help me to troubleshoot this and get it to working again. I don't mind small investments, in fact I have a new motherboard (same one) sitting here ready to be installed if needed. Aside from that, I need to wait several months to get a new computer. HELP me please!

I have had this setup for over a year now and it has been working fine, there have been no symptoms leading up to my problem.

Computer froze, and on reboot would not POST, with no error codes.

Fans spin up, but no signal to the monitor,
Normally at boot GPU fan revs up to highspeed momentarily than ramps back down, but now it revs up and stays up, reset button does nothing have to hold power button.
PSU fan is not spinning during boot up but I am not sure if this fan is heat activated or not.

I have unplugged all non-essential devices leaving just RAM, CPU, GPU.
still no joy.

The last thing I have done is remove both RAM modules, at this point I do get either 3 beeps, then reboot and continuous.
Or I just get continuos beeps.
And the GPU fan does ramp down.

I have tried both Ram modules in all possible configurations to rule out Ram slots, always no beep codes with Ram plugged in.

So this leads me to believe it is either the PSU, or RAM is there any test I can try to tell which one, short of swapping as I have no spare parts handy.
