I made a mistake. In bios, i disabled 'marvell IDE controller' and 'marvell Gbe LAN'. What I wanted to do was to disable the built in network card, which makes my choice to disable 'marvell IDE controller' really stupid.
My computer wont start windows 7 any more even though I've enabled the choices back. I have tried to restore the bios settings to default. Nothing works, just a blank screen. no beeps or anything.
The only thing that happens when I reboot is that it lists the harddrives, and then nothing.
I guess that it is the motherboard that is fried, but is it even possible to fry something only by changing in bios? well, apparently..
try bios flashback check you M/B instuction book. also try unpluging cord from wall also hold down the power button on case to discharge any more power from the M/B and take out the battery for 5 min see if that restores bios settings
