I connected up the components for my new PC, checked everything was connected properly, and turned it on. Early signs were good; it powered up fine, the audio worked, and it seemed to recognise all my hardware. I managed to get into the BIOS, and I quit and powered down without changing anything. The only thing I changed before powering up again was to move a cable that was obstructing a fan; when I turned on again, all I got was a blank screen; no start-up beep, nothing. I've tried resetting the CMOS by switching jumpers about and even by removing the battery, but neither has worked.
The last time I turned it on, it powered down, powered up, and continued to do this over and over, with the intervals between power downs getting progressively smaller. I'd say this was a fault with the CPU, and it wouldn't surprise me as I was the one who fitted the heatsink and fan, but it was on for minutes the first time it powered up with no problems, and the heatsink seems to be fitted in place absolutely fine. Any idea what might have happened?
Thanks,
Phil
