PC Died :( Booooooo

icestar2 · 30-12-2010, 17:28

Tried turning my PC on today and its not responding at all. There is power going into the machine but nothing is booting at all. Not even to the Bios screen.

I'm thinking it's probably the motherboard thats finally given out or possibly the CPU. I've ordered replacements for both but wondered what anyone else thought it might be. I know the GFX, the power supply and the RAM to all be fine.

Tried clearing the CMOS and booting with a basic setup(removed all but necessary hardware) but nothing. Keyboard lights up when plugged in so know there is power going through the system.

Also whats the best thermal paste around at the moment ?

If you are not even getting as far as hearing a beep from the motherboard (assuming it has a speaker attached to the MB) then I'd be suspicious of the PSU. Just because one p0art of the PC is powered doesn't mean it all is.

Your right it does not even get as far as running POST but the Power supply is only about 2 months old and I've tested it in another machine and all booted fine. Only thing's I couldn't test was the CPU and MB as don't have compatible parts around

Remove the GFX and memory, make sure you have a speaker attached to the spkr header connector (not the soundcard output) and try booting.. Does the power light flash? (normally a sign that there's a short somewhere)

If need be also remove the CPU and see if you get any post beeps (the motherboard should beep even with no CPU

although new motherboards with the new post system wil not do this

Arent we gonna have fun when the BIOS is thrown away starting next year lol

Kymmy · 30-12-2010, 18:06

Nah, will just mean those with spares will get somewhere, those without will be lost..

Does mean a boost for the computer industry whilst leaving the user out in the cold

It will keep the returns departments of the component suppliers busy

Unfortunatly I can't find one of them speakers to connect to the MB. I'm sure I had one somewere but I can't for the life of me find were it is. I've searched through 4 MB boxes an still can't find one.

ice, normally it should just work on normal speakers as well.

Thats what I normally use. Just wanted to make sure there wasn't something better around now. Been a while since I followed such things.

Kymmy · 31-12-2010, 09:12

Without the speaker then no post beeps..

If you ordered it to be delivered to you, I can't see it coming tomorrow as it New Year day and Monday a bank Holiday.

Had a similar incident not to long ago and it was the motherboard, as you`ve pretty much narrowed it down to mb or cpu i`ll give 4-1 it`s the mb

Iv`e got a couple of SKT775 pentium 4`s knocking around if you need one.

I meant today as it was past midnight when I posted and it has arrived.

Very Strange problems am having now. The MB is a direct replacment. Exact same model. I've now fitted it and can get to the operating system choice(I duel boot XP and Win7) but as soon as I click on either the PC loops back to the beginning of start-up.(Like its just been powered on)

I can't access windows 7 normally or in safe mode(Loops back to start-up everytime) I can't access Windows XP normally but I can access it under safe mode which I'm currently on now and posting this message.

I can't run any repair - Loops back to start up. Am very confussed. Tried booting one drive or the other alone and same issue. Can't for the life of me understand whats going on. I've read a CPU thats overheated can cause this but I can't be sure.

Got a new CPU arriving next week but for now am stuck. Any ideas ?

Note - In the bios the 12V rail is giving 11.9V and the 3.3V rail is giving 3.2V but this shouldn't be causing these problems I'd assume.

Thanks for the offer Matt but its an AMD AM2 system I am currently using.
