PC Self-Down last night...

Quite a dilema I'm in right now. Was up late last night doing some work, all was fine. I wake up and my computer is down. I leave my PCs up 95% of the time.

The build I'm referring to, in my sig, has only been down three times in about the past 4 months. Once for RAM switch, once for system fan removal (lol yes removal) and the third time for a massive storm where power was out for hours.

Any and all suggestions will come greatly appreciated.


One serious issue, is this mobo did NOT come with a jumper for the CMOS. Utterly beyond me so I may need to dig around the office to find one.

Diagonostic notes: When I first tried to power on, it seemed normal but then the case fans started cycling speed... Noticed the mobo wasn't posting so I killed the power. Each subsequent time after the fans no longer cycle but no boot.

Thanks.
 
Cleared the CMOS with no success of boot.

Further update: Forgot to mention that there are NO beeps whatsoever after power-on.

I have heard this before with SOME mobo/cpu setups that if there is a CPU fault/failure the MOBO will still POST... Since there is no POST of the MOBO and not even a BEEP sequence, this rules out any additional conflicts. I tried disconnecting the HDD, Vid Card, no USB devices. HDD spins up fine when it was plugged in as well as DVD drive. All fans work properly.

I have NOT ruled out the PSU at this point. I have sent in an RMA request with Gigabyte in the meantime.


Please, any additional comments or suggestions will gladly be accepted. Thank you.
 
My new build was working fine, then just shut down like someone yanked the plug.

Fans come on, but never gets to post. No beeps but no speaker. Hard drive never moves data though it spins up. I think I've narrowed it down to ram.

Also, FWIW, I have had a computer that worked fine for a year, then crashed one day out of the blue... and it turned out to be bad ram. Swapped in new sticks and all was well.

Trouble shoot the ram a little bit. Try booting with one stick at a time.
