This doesn't look good. How long has it been that you bought the laptop? Do you have a warranty card? Probably, the company can fix it if it's a glitch. Hopefully, they can repair the graphics card or do something to solve it. Upgrading the graphics card in laptop has 99% of no chances. 

If you don't have warranty card, repairing it would make no sense rather invest in new laptop. This is frankly speaking what you can do.

How long has it been that you bought the laptop?
i bought it since 4 years and half.
Do you have a warranty card?
Yes, but itsn't signed officially from HP or whatever(the fields isn't signed or...)
Really, i tried to contact them alot of times but thier Prices are too expensive so that i replaced the Power Supply since 1 Year and the Ram was shrunking... by other unofficial Support Company.

hey @Zorono,

have you checked if the drivers are ok?.
does the laptop even willing to show something like bios/windows etc?.
if yes it might be a driver malfunction.

have you checked if the drivers are ok?
Most of the drivers are installed and working as well except the display Drivers (Check the screenshots below):

Yes, iam currently using it with Win 7 Pro x86 bits but itsn't working as well at most of times becuase of The RAM's overloading and the corruped graphics-card which prevents me from Enjoying most of its features (Games, Photoshop...)
but when i try to update/install any kind of those drivers which uses the GPU mainly my RAM gets overloaded when i try to reboot my Device after the drivers Download to install it... and then SYSTEM_THREAD_EXCEPTION_NOT_HANDLED with a blue screen and the Device keeps on rebooting.... so that i must use the 'Safe Mode' to roll back the Drivers.

I think something went wrong. because if graphic card corrupt or not respond windows never go to boot screen. or it has minor issue like any circuit cuttoff or burnt resistance. etc.. or try to find correct drivers and install it manually. once i suffer with this kind of problem with my ATI Radeon graphic card. the automated drivers which windows get are not works properly. then i manually install exact drivers of my card and many many new options are unlocked.

Try restoring your computer to factory settings. If you haven't dropped your computer I would try reinstalling the graphics driver.

Try local Computer repair vendor. Seems like, this is problematic.

Also, I thought of why not cleaning the graphics slots if dust have jammed up the system.
