Guys I really need help please no one has helped me so far and nothing has helped...

I've had my PC for a little over 2 years now, it's been working fine, except the past 4-5 months it's been crashing constantly. It's weird because after about 4 hours of constantly crashing and turning on, it no longer crashes. Then on shutdown the thing happens the same the next day.

A few times I have had the error message CLOCK_WATCDOG_TIMEOUT.

I've replaced my HDD and CPU but it's still happening, before you mention, no it isn't my power supply, because the crashes sometimes cause the screen to freeze and approx 1 min later it shuts off.

It's not my GPU obv and the last thing I can think of is my motherboard but I doubt it's that :(

I really need help, the thing is too. It's not malware or viruses, because I completely got rid of my old hard drive and wrote down everything I need to re-download again onto my new one, and them programs all have certificates and are legit.
