My friend brought me his computer to fix, it would not turn on at all. Quick diagnosis told me it needed a new Power Supply. The PC is an HP a530n, and had a 250W PS.
I replaced it with a 350W PS, and everything turns on fine, but I get a blank screen, nothing at all. CD Rom runs, DVD runs, lights glow. HDD spins. I took HDD out and installed in my PC as a slave, works with no problem.
My friend told me the PC had been knocked over during transport to my house. So, I thought to myself, maybe something got knocked loose... I've taken out video card and modem to re-seat. Still not working.
The DVD and CD both operate fine (open/close, lights come on)
Removed PCI modem
Removed AGP Video Card, replaced it w/ brand new PCI Video Card
Still nothing... blank screen
I tried resetting CMOS jumper per HP instructions (moved pin from 1-2 to 2-3 for 10 seconds, PC unplugged, moved it back)
Still nothing... blank screen
Something else I did notice... Keyboard lights do not come on. If I unplug keyboard, and plug it back in, all 3 lights on keyboard light up for 1 second, then shut off...
Does that mean anything to anyone??? Hopefully ???
All input appreciated... I promised my friend I'd fix his PC, but this one has me stumped !!!
Could the Motherboard be shot, and if so, how to tell? Can the HP's have their motherboards replaced?
Does anyone have any ideas?
