I recently went out of town on business and took my desktop with me, I never really had any problems until I got home...
The first thing i noticed was when i turned it on i got an Intel screen (mobo manufacturer), and nothing else, the HD light would stay on and never blink, but the comp wouldn't go to windows. I thought it might be booting slow for some reason so i gave it like an hour but nothing happened. After a dozen or so resets it finally went to windows.
Next problem, now that we're in windows, the video card i installed 4 months ago isnt working, and its running on the onboard vcard with a generic driver. The computer wouldn't detect my good card, i fooled with that for 5 hours or so, removing all trace of ATI programs and drivers from my comp and trying to reinstall it from scratch (hardware and software), using the CD and also the new CAT drivers and software on the site, but an error message would come up during install saying there were no components to install the software for, and shutting down the setup. i checked the device manager and noticed my VGA controller wasn't working properly and there was no way to install or update the drivers.
next day i notice that DX9 wont work with the generic drivers on the onboard card, so i update those and get DX9 working for the time being. a couple hours later i shut down my comp for something and the worst of the problems start.
the computer won't boot up at all, when i turn on the power the power light comes on and the CD drive flashes a bit to show that its working, but the HD light stays off, doesnt blink at all, when i turn off the power the HD light blinks as it goes off. i get no display on the monitor at all black screen...
ive tried removing everything not needed for boot up (everything other than a stick of ram and the display), nothing, i tried booting without the hard drive and nothing, i replaced the BIOS battery...
anyway sorry for the long post, thanks in advance
