Try booting up in Safe Mode.

 

Does the PC reboot and try loading the operating system again or just sit with a blank screen?

Also: Change your thread title to be more specific about your problem. We now know what your problem is by reading the thread, but ambiguous thread titles get closed.

 

soory for the headlining


yes after reboots it just sits ina blank screen

 

Is it actually rebooting then, or does the screen just go off? The latter indicates a graphics fault, whereas the former could be many different things.

 

Its just goes off

 

Could be a graphics fault then. What happens if you boot into safe mode?

 

still the same

 

When exactly does the screen go blank?
