I recently received a motherboard(AMD Processor) from one of my friends with an 80 gig hard drive as the main drive. I decided to switch to my old hard drive which is 20 gigs(from an intel celeron motherboard), so i can have all my DESKTOP settings and so forth. I made sure the settings in the Bios were right but the pc wont start up afterwards. It immediatly shuts off right after the RAM check(SCREEN turns off). I made sure it saw the 20 gig as the main drive(yes i remmembered to make the other 80 gig a slave drive) but yet it still will not boot up. Is the problem that i over looked something in the bios? Or is it the TYPE of motherboard I used? Please email or im me(Dntmesswtheryman) or just post the answers under this topic. I'll take all the help i can get get.
thanksWhen you're moving Windows to a new MB, it's an iffy situation.  You can stack the desk in your favor by doing a couple of things.

Uninstall drivers for any hardware you won't have on the new system.

Uninstall any motherboard drivers, LIKE the VIA 4-in-1 drivers or the Intel IAA drivers.

In Device Manager, uninstall EVERYTHING under IDE ATA/ATAPI Controllers.

Shutdown and do NOT reboot this disk on the old system again.
