try to replace the power supply. maybe its not giving enough power to boost up the computer.

hi,,

if your pc is desktop type..

u can see a two screw at the back.. unscrew that two screw..

Every case is different, and I particularly do not know yours. In most cases, besides a couple of holes for a physical lock on the case, there's a BIOS option that allows you to LOCK the case electronically. Find the key that gives you access to the BIOS upon boot (usually F2, F10, etc) and press it. The option you're looking for should be under a menu item that sounds like System Security. Find the one that reads something like "Intrusion Detection", and disable it. Make sure you save the change prior to rebooting.
Good luck!

look on ebay for used compaq power supplies.

there are a few programs out that can be used to reset xp and vista passwords but most are corporate software like bestbuy has MRI software that can reset or you can call HP and order recovery software approx 20 bucks well worth it

have you installed an Operating Sysem on this hard drive?

A NVIDIA GeForce 6200 or similar will fit into the compaq slimline case. You need to get the slimline model, then modify the steel bracket to get it to fit. This is what iv'e done to a EVO (P4 1.8 GHZ)and
