I was given a laptop to take a look at and it has this very weird problem its an old HP Compaq nc8000 when you power it on the fans rev up screen remains blank stays powered for a few seconds and turns off no beeps or anything, the power led is not on instead the hdd led is constantly green and battery led is orange. I tried running it with no battery just plugged it to the charger still same. I swapped the ram over to the second slot still nothing.
Once it booted up screen came on and it went into windows disk check thing and crashed at 6%. Another time it booted I skipped the disk check and tried logging in but just crashed.
The heatsink is clean no dust.
Also tried using vga on a monitor but didnt work.
