Answer» Hi guys and gals. I'm trying to repair this computer my friend who is undergoing treatment for cancer and it would be great if I could get it REPAIRED. The problem is that it won't boot. I'm quite sure that it is not the power supply because the lights come one, the fans are running and the DVD Rom drawer will open and close. I can't even get it boot from a rescue disk. I tried a different video card; no joy. I checked all the connections in the box and re-set the RAM chip. The hard drive appears to be running. Is there anything else I could check?although it does sound like the PSU isn't the culprit, you certainly couldn't rule it out. I've had PSU's 'look' good, but once replaced, TURNED out to actually be bad after all - so worth a swap with another if for no other reason than checking off options from a list. with the RAM removed, what POST beeps does it give? if you can get into the BIOS, does it show the hard drive as detected? what's this rescue disk? an external caddy HD or a DVD? has the BIOS been set to CHANGE the boot order to check those devices before the internal drive?There are no post sounds. The problem is that I'm not getting anything on the monitor so I can't boot into the BIOS. The rescue disk is one I've used often is OTLPE rescue disk.

if you can get into the BIOS, does it show the hard drive as detected?

has another monitor been tried both ways ? ?

I tried another video card. This model has an on-board video card. I also tried two monitors.
