Hey all, long time lurker here. I recently came into the possession of an old HP Pavilion 762n. Plugged it in, pushed the power button... heard fans spinning and nothing else; no beeps, no hard drive clicking, no signal to the monitor, nothing.
I decided to open it up and apart from copious amounts of dust, nothing seemed to be awry. The video card fan looked like it was grinding a little, but that shouldn't cause the POST to fail.
Anyway, I started disconnecting equipment to isolate the problem. Out came the videocard, RAM, hard drive, CD-ROM drives, floppy drives (one at a time, of course, then all at once).. Still nothing. I even tried running it without a CMOS battery in.. nothing.
So, should I be looking into a new motherboard? Is there anything else I can try? This isn't going to be my main computer and it can't get any deader than it already is, so extreme measures are not a problem. Thanks!
