PC starts for five seconds, then shuts down

So I get home last night, and my older PC won't boot up. It powers up, the disc drives light up, and the first splash screen starts to appear on the monitor and then it shuts itself off completely.

Would this be a hard drive failure? And if it is, is there any way to recover anything from that drive without a degree in computer forensics?

I would check to see if the heatsink is seated well on the CPU and that the fan is working first.

I'm glad you think I know what any of that means, lol.

Certain processesors turn themselves off when they overheat to prevent the chip from being damaged. What he means is that you should open up you computer case and take a look at the processor. It will have a huge metal thing on top of it, called a heatsink, and possibly a fan attached to that. This fan heatsink unit may not be properly connected to the processor which results in the processor overheating and turning itself off.

You can try to adjust the heatsink to sit atop the processor better to keep the processor cooler and see if this helps. It doesn't sound like a harddrive failure. Most harddrive failures are associated with lots of strange noises such as clickings coming from the computer. This seems more like a problem with the processor overheating.

I opened her up and gave everything a good cleaning. After that, I could get the PC to stay powered up, but it wouldn't boot up. The power stayed on, but nothing ever loaded and the monitor never came on.

Might be a bad power supply too. I had the problem where it would reboot everytime it got the Windows logon screen. I was looking for bad cards, memory, overheating and finally discovered it was the PSU. But shutting off completly usually means overheating.

It's probably the fan. That sounds like a problem my co-worker had last week.
