Ok, Im a newbie at this but for being self taught, im doin ok..lol, my latest project is driving me nuts, eMachine..T4480. power suply was supposedly only thing wrong, but while i was out, my buddy, ( trying to help) took my hd and installed xp pro....so now i have to probs...wont boot...and i cant see anything. evertime i hook the monitor up..it immediatly goes to power save mode. I cant even see what im doin even if i did clear or reset the cmos through the jumpers. any suggestions?

Does safemode work? (Tap the F8 key a split second before the Windows logo appears during bootup and choose Safe mode from the menu)

safe mode

it probably would work...'cept i cant see any thing at all on the monitor screen...what could be causing this?
