My old PC won't turn on!

[Thiele]

I changed a BIOS setting last night (not sure if this is why i can't turn it on) to be able to turn it on with the keyboard, now i can't turn it on with either the button or the keyboard. I'm sure that setting would be harmless but i can't turn it on! I have no idea what brand the motherboard is but the BIOS says:

686
AMIBIOS
1999
AP78
3182

I know there's still power going through the PC because the monitor which goes through the PC still has power.

Any help?

open up your computer case and find a small circle battery; take it out for a minute and put it back in. restart computer. (suppose to reset/clear your bios)

Ok i was just looking at other threads and it said you can do that, thanks. Now if i can get that darn thing out.

EDIT: Fixed! Now it turns on and comes up with a message saying CMOS settings wrong or something. Hopefully i can fix that if i can't i will ask again.

EDIT2: Fixed that too, also found out the mainboard is MSI.

Thanks beer-2k.
