Running desktop system in sig with Antec Smartpower 500W.
Yesterday, I tried to overclock my Venice CPU to 2.4GHz using "300MHz" mem divider, 3X HTT, and Vcore's from 1.4 to 1.5 but it wasn't quite stable in Windows. So I gave up and set it back to the 2.2GHz, "333MHz" divider, 4X HTT, and 1.4V that I had been running for the past few months. I ran Prime95 for 8 hrs after that, and no errors were reported. Used the PC for another hour or so after that then shutdown and went to work.
When I came back, the PC wouldn't boot. The motherboard LED's would flash once and the fans would all spin once, similar to when you turn off the switch on the PSU and press the power button to discharge the capacitors on the motherboard.
At first, I thought that maybe their was a short somewhere so I removed the motherboard but still no go. I tried using memory sticks one at a time in different slots, although I suspect that it isn't the RAM since from my previous experience with bad RAM, everything will power up but the motherboard will at least beep error codes. I shorted the green and black wires, and the PSU started, so I don't think that's at fault. I also tried clearing CMOS via the mobo jumper.
That leaves me thinking it's either a bad CPU or bad mobo. Can these things die delayed deaths from failed overclocks? But the system was Prime95 stable when I set back to my previous settings ... only to fail some 12 hours later?
Is there any way to isolate which is at fault without CPU or mobo swaps?
Or maybe I overlooked something else?
Thanks for your help!
