If a factory restore from restore discs fail, the machine often needs repair. One last idea. Are the BIOS settings the default and did you clean the vents with the usual canned air?
Pc -hp dv7 4020sa
Os- windows 7
Basically two years ago i purchased this laptop and a few days ago the computer just shut off. When i tried turning it on i got a black screen after the windows boot logo. I tried connecting a external monitor via the vga port but same thing. I checked all the forums and found out the display drivers were the problem, i went into safe mode(worked:D) and uninstalled them and the laptop seemed to boot up fine but the display was all grainy and big. So i thought the best way to solve this would be to do a complete factory reset.
Now after the reset im getting the same problem but this time i cant even boot into safe mode because it says i have to do a "setup new computer" process in normal mode.
Please any help will be appriciated.
