Ok its like this... I have 2 64MB ram chips in my mobo and one empty slot. So i went to put kinda an old RAM in and when i turned the computer on it beeped about five times. I turned it off and took the RAM out. Now when i turn it on it powers up but nothing appears, it doesnt have any type of boot sequence. The graphics card is on, the fans are on and the harddrive is powered up, but there is no screen output. Any help on this one?
