Solve : PC shuts down without warning - Not overheating.?

1.	Solve : PC shuts down without warning - Not overheating.?
Answer» Hi guys, I bought a PC in September and ever since I've had it, it's been shutting down without warning at completely random times. It's some times even after 10 minutes. The seller has had the PC back several times, swapped the PSU with a 700 watt one and put a very large fan in the PC, next to the processor. The computer runs quietly and seems to have a lot of air coming through it. I would say it only really happens when I'm gaming.. and not just modern gaming, I'm talking DOSbox stuff, so I really don't think it's the graphics card struggling. Some times it happens when I'm gaming on one monitor, with a film on in the background on the other monitor. However, I'm not talking about an incapable, old PC here. The seller assured me I could even play Battlefield 3 on the PC, but I'm struggling to play Dark Forces on it. There is nothing really showing in Event Viewer, other than the PC unexpectedly shutting down. On one occasion, there did seem to be a slight burning smell. On another, there was a blue screen and I wrote it down somewhere, but it's been misplaced... since I thought the issue was resolved. My initial idea is it MUST be hardware compatibility. I thought some third party software is conflicting with another or a driver causes the issue, but I thought I would have had found something in Event Viewer. One thing to mention, is the PC is plugged into a long extension cable, being shared with another 5 appliances. Could this possibly be the issue and a voltage one? Any help would be gratefully appreciated. Many thanks, Spyke [attachment deleted by admin to conserve space]It takes over 100 little parts to make a motherboard work right.

Hi guys,

I bought a PC in September and ever since I've had it, it's been shutting down without warning at completely random times. It's some times even after 10 minutes. The seller has had the PC back several times, swapped the PSU with a 700 watt one and put a very large fan in the PC, next to the processor. The computer runs quietly and seems to have a lot of air coming through it.

I would say it only really happens when I'm gaming.. and not just modern gaming, I'm talking DOSbox stuff, so I really don't think it's the graphics card struggling. Some times it happens when I'm gaming on one monitor, with a film on in the background on the other monitor. However, I'm not talking about an incapable, old PC here. The seller assured me I could even play Battlefield 3 on the PC, but I'm struggling to play Dark Forces on it.

There is nothing really showing in Event Viewer, other than the PC unexpectedly shutting down. On one occasion, there did seem to be a slight burning smell. On another, there was a blue screen and I wrote it down somewhere, but it's been misplaced... since I thought the issue was resolved.

My initial idea is it MUST be hardware compatibility. I thought some third party software is conflicting with another or a driver causes the issue, but I thought I would have had found something in Event Viewer.

One thing to mention, is the PC is plugged into a long extension cable, being shared with another 5 appliances. Could this possibly be the issue and a voltage one?

Any help would be gratefully appreciated.

Many thanks,
