Ok so I have a Compaq Presario SR2020NX Media Center pc. I attempted to install windows 7 but when the disk was in the drive during boot the monitor would not come on. i got the pc to boot just fine into xp and did the install of windows 7 through the xp desktop. now the monitor will not come on at all even with a boot disk or an older version of windows. I have removed the ram the battery i have removed and reconnected power and even gone as far as unhooking all cd rom and hard drive i get no beeps and the pc sounds as if it is booting itself just fine but still no monitor. i know the monitor works as it is the one i am staring at as i type this and i do not think it could be a hardware issue as it all stemmed from windows 7 install if anyone has any ideas or suggestions please help.
