Question

pc keeps shutting down randomly, please help

Dec 8, 2012 5:48PM PST

Hi

My pc keeps switching off randomly. Sometimes I use it for days and nothing, other times I mereky switch it on and 5 minutes later it just switches off completely.

Once its off, I have to pull power completely before I can restart. I tried 3 different rams already and I still get the same.

Asus AM2-VM HDMI motherboard
2gb corsair ram
2gb kingston ram
2x1gb samsung ram
Amd 6000+ cpu
450watt psu
Ati Radeon 4350 graphics card

I checked the temps and everythings fine. Mb at 40 degrees, cpu at 47degrees and greaphic card at 50 degrees.

Ive reinstalled windows 7 ultimate and updated it with all updates available. Also updated the bios to 5001 beta.

Please help

nothing in event log

I checked just now and all I could fine is a kernel error. Windows did not shut down properly. Thats it.I tried 3 different sets of ram, cleaned out the pc properly, changed sata hdd to a ssd and nothing.

Experiment.

Boot from a Linux disk (Ubuntu is fine) and do what you usually do (browsing with Firefox will be fine, editing your documents with OpenOffice will be fine also).

If it still shuts down unexpectedly (could take a few days, given your story, could be in 5 minutes also) it's definitely a hardware issue. Otherwise it could still be a Windows issue, although that's unlikely.

Thanks for the response.

I also believe that its not windows as everythinghng I check is perfectly fine.i just ran everest and that doesnt detect anything ei ther. Also tried sisoft sandra pro and thats not picking up anything. Is there no other software that might be able to pick up the problem?

Im getting so irritated with this at the moment...

Seems okay

Okay, I did the following and it seems better:

1. Disconnected 1 of the 3 hdd's
2. Changed the v-core voltage in bios

Now everything looks way better. Busy running a burn-in test from si-soft sandra pro and running smoothly.

I'll update and close if this solves the problem. Most likely...I'll need to replace the psu
