I've been dealing with this issue for a few weeks now, and got the machine running the first time with ideas off these forums. Except, I wouldn't be here posting a thread myself, if the new setup had lasted more than three days. It didn't.
Here's what happened. This is a self-built, liquid cooled computer, and had been running fine for a good four years. Last week, suddenly windows froze. A few days later it froze again. Then, upon restarting, the machine would only go into post every other time, and freeze or randomly restart some time down the road. And finally it got to where I was getting no post at all.
I went through the usual suspects first. New motherboard battery, clearing CMOS, switching RAM sticks around. Nothing changed. My local big store has an easy return policy, so I also tried a new power supply and video card. Still nothing. I then got a replacement motherboard. No change. Only with a new (bought used off of ebay) CPU that I tried last, the computer came back to life, boom! And it felt good, let me tell you.
Except then, on the third day of moderate use, there was another random freeze (Again, this computer
ran like butter for four years. No funny stuff whatsoever, linux OR windows). I was a little worried, but kept using it. For the rest of the day, the machine shut down and restarted with no problems a few more times, as I was on it.
And then, this morning, again no post. All symptoms exactly the same as last time.
I've already ordered another processor. While it's in the mail, I wanted to share this experience and see what the ideas are as to what might be going on.
To be clear, when disaster struck the second time, I was using the same power supply, same graphics card, same RAM, with a new motherboard and a new (bought used) processor.
Some thoughts of my own:
-when testing the power supply with no load, the 3V leads are a little over, the 5volt leads are a little over,
but the 12 leads, both + and -, are at about 10.8. But then, people tell me the 12V leads are for the hard drives only and have nothing to do with the processor.
-when putting in the new processor, I used some $2 thermal paste off of ebay. Should I instead have gotten something fancier like 'arctic silver' for $8?
I'd appreciate any thoughts. Also I promise to close up this thread properly by posting the solution, which seems to be overlooked on forums often.
