Black screen of death

[puk284]

Hi after my computer boots it gets stuck on a black screen with a mouse cursor in the middle. I have been researching and reading for a solution but have not found one that works for me. I can't boot into safe mode or even safe mode with command prompt so i cant do any registry fixes which some people suggest. Iv also tried last known good configuration but that didnt work either. ctrl + alt + delete doesn't work either. iv tried doing a clean install and using the windows diagnostics and recovery toolset version 6. but they havnt worked either after the loading files bar the KSOD comes back again, it is like the computer cannot read the discs or it wont boot from them. Please does anyone have any solutions that i may try? Thank you very much for your help in advance.

Its look like the problem due to viruses so better to check for viruses with good updated antivirus.connect your hard disk to another computer as secondary which having good antivirus and scan there. if virus is not problem then boot from windows disk go to repair console and use chkdsk ..
