My Compaq Presario CQ62-238DX powers on but nothing happens, no monitor no sound even though the fan's working and the keybrd lights come on. What can I do?

SOURCE: monitor screen stays black even though it's on

Remove the memory from your unit - power it up it should beep if full communication is still happening across your m/board. No beeps you board has died. if it beeps and your using two diffent memory modules just fitt one leave the battery out and power it up = if no display pull power swap out the memory and try again. if display occurrs you have a defective memory module - throw that failed unit away

Try booting into the BIOS Screen and resetting to factory defaults. If that fails suggest swapping the hard drive out and re-install the Operating System - Save your old data and migrate the data off the old drive. You can buy an external drive adapter to connect the harddrive to a USB port to migrate you data.
Good Luck!
