HP D5000t (Vista), short cycles on start up

[sandwedger]

PC was hibernating and did not respond when mouse was moved. In the past when this happened, I just manually powered down and restarted and all was okay. This time when I press the power button, it starts to run for a few seconds, then stops, and starts up again, repeating the cycle endlessly. Could this be a power supply issue? Worse?

It could be, have you looked at the system board for bad caps? I take it when you say it starts for a few seconds and then it loops, you just have some fans spinning, no video? or is there video? does it start the OS load, and than reboot? Or never gets to the OS. have you tried a bootable cd or thumb drive to see if it is the OS partition.

There's no video, which I take as being a good thing. The fans come on, whirring excitedly, then crap out after a few seconds, then it starts all over again. When I removed/replaced the RAM sticks I did not notice any bulged capacitors. I'm going to try a power supply first and hope for the best.

Yeah, hopefully you could borrow one to confirm your theory. I'd bet on the power supply though.

Clear CMOS first!

had a similar issue, and clearing out the CMOS (taking out the battery, unplugging the PSU from the wall outlet, and holding the power button for more than 10 sec. (depleting the caps)) was the ticket for it to boot back into the OS...

Couldn't hurt and it's free UNLESS you don't know what settings to put back into the BIOS. This would particularly be the case if you were booting from a RAID device and the RAID controller was reset.

At last, back to normal! Installed new power supply, and it ran, but no display. Removed/reattached all connections, pulled video card, reinserted, pulled/reinserted memory sticks, tossed some chicken bones, burnt incense, put hat on backwards, pulled pockets inside-out, stood on one foot, and now the thing is up and running! Thaks, guys!
