Hi guys,

Well, I just recently upgraded to windows 8 beta 64 bit, i've been loving how sleek and quick it has until today...

today suddenly the black screen problem occur. my explorer.exe is already running. i cannot access the internet coz my internet browsers have been blocked by my antivirus. after deliberate consideration, i've uninstalled the antivirus. But there is no any help in this issue.

does anyone know what could be causing this? if you can come up a fix for this would be highly appreciated.

Many factors can lead to such black screen proble:
1.power faulire of the scrren. 2. no power supply to the motherboard. 3. damaged graphic card or its bad connection; 4. bad contact of CPU. 5

bad contact of memory bank; 6. virus attack. 7. check the plugfest.
