got quite a challenge for those experts out there.
A long time ago I had installed a copy of XP on my computer that I had borrowed from a friend. I found out that the cd-key was blacklisted as being pirated, so I got myself a legitamate cd-key. I changed the cd-key using a thirdparty program, but must have accidentaly entered an invalid key. When I next restarted my computer, it would not even boot to BIOS.
I flashed the BIOS, and got it the boot. It told me that my hard drive was disabled, so I intended to reinstall windows. On the next restart, it couldnt boot to BIOS again. Even after I flashed BIOS a few times, I cant get it to boot. The power comes on and CPU starts, but theres now no signal to the monitor.
Please help if you can.
