Computer crashing

[GingaNinja]

So every time I launch a game, 5-15 minutes later my computer will just reboot. I can leave my computer on all night and it wont reboot but just a few minutes into a game causes a restart. I've been to a computer repair store, first they told me it was my hard drive. After replacing my hard drive with a new one the problem persisted. So I brought it back to the repair store, and was told the video card was the problem, now I've replaced it with a new one and still my computer crashes when I play games.

Does anyone have any idea at all as to what can be causing this and why? Any help will be greatly appreciated

it is possible you PSU is failing under load.

Just a few questions to get this thread going...

1. Did you completely reinstall your OS after you replaced the hard
   drive, or transfer/mirror the data from the old one?
2. Does the problem occur with ANY game you have, or just a few?
   (please list if just a few)
3. Will the computer crash when sitting idle in the game's lobby/main-
   screen for 15+ minutes?
4. Could you post your current computer specs?
