PC freezes at Bios screen on startup

[yonni]

I couple of weeks ago I had some problems with an internal fan on my PC. I took the case off and discovered the wire was loose which seemed to fix it. I also installed a diagnostic tool that recorded temperatures and fan speed etc. It said that only 1 fane was working. I had a couple of error messages about a fan not working at startup but just pressed F1 to continue as I was in a hurry. Now the PC freezes at Bios the screen on startup and there is no fan noise at all. Ok, my bad, but have I fried my CPU or Motherboard and is this worth fixing or should I just take out the HDDs and stick them in a new machine?

Is it saying CPU fan or system fan? If it's a system fan, just disconnect it anyway, and buy a new one. Depending on the size, I have some here. (92mm).

If it is your CPU fan, it could be the thermal cut-out kicking in as soon as it starts, so replace your cooler, and apply thermal paste to the CPU, remembering to use IPA to remove the old stuff. I also have some of them here, depending on what CPU you have. Most I have are Socket LGA775, and LGA1156.

If it was a dead CPU you wouldn't even get as far as the bios screen. You may have knocked a connector for the hard-drive, knocked a memory module out of place, that sort of thing.

Try pressing F2 or Del to get in to set-up (If it lets you) and select 'load defaults' or 'load failsafe settings' and reboot. That may reset things.

Failing that, take the power cord out, take the side off and remove your cmos battery for 20 seconds then put it back, and then try and reboot. DONT TAKE THE BATTERY OUT WHEN POWER IS CONNECTED. Not for your safety, but because you are likely to kill your board.

Whatever it is, it doesn't sound like you have killed it, because it is booting to bios.

been in France for a few days but really need to get this fixed now. It says "Press DEL to run setup, press TAB to display BIOS POST message" nothing happens when I click either though. looks like I'm going to hva e to take it to PC World as I wouldn't know what a cooler even looked like.
