Hi all, I'm new to the board (although I use TH for all my hard ware needs!)
I'm at my wit's end with a PC that I built about 4 months ago. Here's the hardware list:
CPU: Intel Core 2 Duo E6600
RAM: 2x1GB Crucial Ballistix PC2 8500 (replaced under warranty)
MOBO: GigaByte P35C-DS3R (replaced under warranty)
GFX: XFX 8800GTS XXX
Case: Antec P182
PSU: Hiper 580W - replaced with Zalman 600W
The problems first started from the beginning when Vista kept giving BSoD. I put this down to Vista being pants, so went back to WinXP64. Problem persisted so I RMA'd the MOBO and RAM. Problem went away for a while.
Last night, I switched the PC on, Windows froze at the loading screen. I powered it down, then up again. The PC has since then gone into an endless power cycle loop, where it powers up (fans come on, HD's spin up), 2 seconds pass, powers down. I have unplugged everything bar the CPU and it makes no difference. The only thing I have discovered is that when I unplug the separate 12V rail, the whole thing powers up, but nothing happens. No POST, nothing on screen. To add insult to injury, the P182 doesn't have a built in speaker - so I can't get any beep codes (and I don't have any spare ones knocking about)!
So I was wondering if you guys might know what this power cycle loop is. Is the CPU dead?
Thanks in advance!
