Hi, my computer wont start up all i get is a blank screen, but apparantly the caps and num lights flash a code which mine does. I get 4 flashes which according to the hp website is a Graphics controller not functional. Does anyone know what could be causing this or had this problem. I really wont to just be able to fix it without the hassle of going through Hp.

Any help appreciated

Try a laptop(notebook) hard reset

Remove the battery and ac adapter power from your laptop

press and hold the power button for about fifteen seconds.

reinstall the battery and then press the power button to start your laptop.

please report your results here in your thread.

OK.

start up your laptop again and keep tapping the F10 key as it starts up.

Post here whether or not you can access the HP Recovery manager.

(hopefully you didn't delete the 😧 Recovery partition when you upgraded as that is not a good plan)

You can restore your PC to the previous OS from the Recovery partition or the HP Recovery CD set (that you should have made before the upgrade) and retry the upgrade again.

No luck again cant access the hp recovery mode, its like the computer isnt booting up i cant access anything just a blank screen and the flashing caps and num lock lights. I insert my recovery disks and nothing happens.

Any more ideas? i might take it to a PC engineer i think the problems with the graphics chip or the motherboard.

Thanks

I just cant get passed this black screen so i have no way of doing anything it must be an internal problem, looking through the forums other people have had the same problem but theres been no solution yet, im just gonna have to deal with HP customer services...

Try removing the hard disk and then starting up the PC. That way we can isolate the issue. If you make it to the BIOS screen then you hard drive might be faulty, not your motherboard
