Ok seriously, ya gota post what motherboard ya have here, before we can give ya any advice.... before yer computer starts up starting hitting delete or f4, just hit em both untill teh bios screen pops up then tell us the mobo yer runnin, im sure there is a way to do it in windows, but shit, i forgot where and how.
Write down the name of yer mobo, it should be at the top somewhere.
It'll say MSI k800-Blargh or ABIT-something or soltek-Blarghkt800 or something along those lines, write that down, then come back and tell us!
