Damn computer

Postby bobthebob1234 » Fri Apr 22, 2011 4:21 pm

Ok poeple this is serious now.

When ever my computer has been off for >5hours it has issues starting up.

Basically what happens is I turn it on at the wall, turn it on, then wait a bit, it dies (windows bsod or ubuntu just freezes), I hold down power button, it turns off, I turn psu off, wait 10 sec, turn it psu on again, and all is ok.

Sometimes I can log in to ubuntu, then things start dying slowing; I will get messages like 'bla bla program quit unexpectedly, do you want to restart it'

I have replaced motherboard, ram and now psu.
This is what I currently have:

Asus M4A89TD Pro USB3
AMD Phenom II X6 1055T
GeForce GTS 250 graphics card
OCZ 6GB (3x2GB) DDR3 1600MHz/PC3-12800
850W Antec PSU (was 500W)

so basically having brought 2 pcs (I'm giving the other one to my brother, aren't I nice?) i'm a bit angry that it still don't work as I want!

I was convinced it was the PSU but after replacing that it still don't work. Grr

Does anyone have any suggestions on what to test or replace next?

(Oh and when I run a mem test when I first turn on I get a bunch of errors, and if I run it after turning psu on and off they go away)
For certain you have to be lost to find the places that can't be found. Elseways, everyone would know where it was

It's still a faulty PSU... You probably got yourself a 'monday-morning' device ;)

I would agree this looks like a power problem. As you have changed the PSU it could be the power connector on the mother board which is faulty which means changing the board out.

There is a possibility that the mains could be faulty. Without an electrical tester the only way to check is to plug the PC in at another house. It could also be a faulty connection in the cable between your PC and the mains socket.

I've changed the board as well.

I have tried it at home and at uni (>300 miles apart...), same result. Using new power cable that came with new psu.

Poor thermal connection between CPU & heat sink? Hard drive problems? A "dry" joint on the case power switch?

What does the BSOD say?

It reads like a video card initialisation problem.

Working in the low memory area but not in its native mode on cold start.

Try a temporary replacement with a known good video card to prove.

Ollie: Don't think so, just got me a fancy new (closed circuit) water cooling system, rocking cpu temps of 26oC (used to be a whole load hotter)
Hard drive slow but working (I think/hope)
Also got new case.

Bazza: I've turned my computer today so won't be able to look till tomorrow but I'll try and take a photo. From what I can remember it defiantly says something about memory.
The graphics card is the oldest component in the box, but it is only a couple of years old :(
