Instant Random Shutdown l

Specs: Windows 7
I've had the same computer for a few years. Yesterday I took it apart, and now when I put it back in, it still runs fine(for about two minutes), then shuts down without warning- A complete, absolute, instant shutoff. HELP?

Overheating?

Did you take the heat sink and fan of the CPU?

If so, did you replace it correctly applying thermal grease in the recommended way.

Also make sure you haven't accidentally pulled any thin cables off one of the fan connectors at the fan or motherboard end. They just slide on to the connectors without any locking mechanism and are therefore easy to pull off when you are poking around in there.

I always check all the cables at both ends before shutting the case.

"Yesterday I took it apart"

Why did you feel it was necessary to do that? More than likely new thermal paste wasn't used or it was applied incorrectly.

bi-yearly cleaning. I figured it had something to do with the cpu heat sink, but after working around with that, it still shuts off randomly. I'm currently on the computer and this is the longest it has been on without shutting off(2 hrs now), but then again, it has been running idle for most of this time.

Lok at this. These instructions are for Intel CPUs. There are also instructions for AMD CPUs which is slightly different.

There is no need to remove the heat sink from the CPU for cleaning. If the fan is a bit crappy then can be removed by itself without disturbing the CPU and heatsink.
