PC keeps randomly freezing and crashing

Hi everyone,

I hope there is someone out there knowledgeable enough to help with this...

I have a custom built computer, and for the past year or so it has worked fine no dramas. All of sudden the other day, it froze. I could still move the mouse around fine, but clicking on stuff didn't do anything, it was unresponsive. I tried alt+ctrl+delete, but that wouldn't work either. I couldn't click on start>restart either. So I pressed my hard reset button on the tower and even that wouldn't work. Eventually, after about a minute, it decided to restart on its own, but during the restart it froze on the bios selection screen that pops up and wouldn't progress beyond that. Eventually, I just held down the power button on the tower until it shut down completely. I then pressed the power button again to turn it back on, it came up with "your computer didn't restart properly message" and then came to normal.

Ever since then, this has been happening frequently, like every hour or so. Doesn't matter what I'm doing on the PC, it just randomly freezes and after a minute or so starts to restart. It now comes up with a message that its trying to look for a boot CD, even though I have the HDD as the first for boot. When I see this message, I just hold down my power button again, switch off the PC, then switch it back on and it's fine for another hour or so.

I've also tried reformatting the PC and reinstalling windows etc, hoping that it was just some sort of software glitch, but that didn't fix it unfortunately. So my guess is it's something hardware related?

I've read on some other threads that it might be overheating, but I doubt it. I have multiple fans on the tower going high speed and also an aftermarket cpu fan as well. Never had an issue with heating before.

Does anyone have any idea of what this could possibly be? I don't have any other computer parts so I can't really do the 'trial and error' thing. I'd really need to know exactly what computer part would be causing the issue and I suppose I'd have to replace it if necessary...hoping though that it won't come to that.

Any help would be much appreciated! Thanks!

Note: Running Windows 7 64-bit.

where to start?

1. check all the power connections to the mobo - make sure all cables are plugged in properly.
2. remove and reseat the RAM modules one by one
3. check the capacitors on the mobo - make sure they don't look out-of-shape. (unlikely)
4. try a different PSU

Pulled the whole computer apart, cables and everything. Checking everything over and then reconnected it all. However, problem still persisted...

Since I lack the extra computer parts to test, I threw in the white flag and paid for a technician to come out and help. Turns out it was the solid state drive (SSD) that was failing, and it simply needed a few firmware updates.

So for people who might be having the same issue, it was a Crucial SSD and it was shutting down about every hour. Once the problem was diagnosed, a quick google search revealed others who had the same issue. So update that firmware! :)
