Hi, My name is XXXXX XXXXX I'm looking forward to helping you resolve your computer related problems.Does it startup normally and then go blak or does it dail to start?RichYavacotech
Starts normally. Stops at any time without warning, then restarts.
Assuming that your CPU fan is up to speed and the internal case temperature is not building up too much it's hard to diagnose these kind of problems.
Did you ever try to fix something that's working? Real old gateway desktops used to have a problem like this due to swollen capacitors on the Mobo. But I doubt if your machine is that old as you are running win 7.
There's no sense in guessing and just replacing components at random. Sorry, I don't have a better answer but I would leave it on continuously (with all my data backed up) and wait for the problem to get worse to the point where it fails almost all the time and the problem can be isolated.
According to the computer health status in the BIOS/cmos, the CPU fan is functioning usually around 1000-1300 rpm, and I have relocated the tower to a place where there is no restrition to the air flow of either fan. This unit is not yet two years old (built January 2010 according to a stamp on the inside of the case). "Watchful waiting" is not an option. I've been doing that for nearly two months and, if anything, the incidents have become less frequent.
While waiting, it shut down again and restarted.
I did find the cpu fan running at 1377 rpm. cpu temp of 25 and system temp of 40c. If heat could be an issue, there is a vent for another fan which I could install pretty easily and inexpensively
The only thing I can think of is to remove, clean and re-install the RAM one stick at a time. If this doesn't work let me know and I'll opt-out and open this question to all computer experts. Hopefully another expert will have another approach.
Yes, use 99% isopropyl alcohol.
