Before i ask the question, let me point out that this is not a hardware issue. I have a clean install of vista on another hd that runs on same hardware, i am pretty sure its a corruption of a drive or a file, i presume it might be video driver.

When windows wont start via normal boot i just get black screen after initial load up of os, so i boot into savemode, I end up having black screen with a mouse pointer visible, after initial load of os. The shut down button is responsive.

Of course, I can install clean copy of os, and prior to that can retrieve all other files that i need by accessing hd itself, i can restore my pc from my external back up as well.

Although i have all these options, i was wondering if there anything else i can do that can help me fix this issue.

In save mode, it looks like I am capable of logging in after initial load of os, even though i cant see the process it self, i do see the mouse pointer. By visual memory i navigated to password field, and entered my password, hit enter, I get the loading mouse pointer, nothing really changes, same black screen and mouse pointer, but when i tried to access task manager for a second i got a safemode watermark at all four corners.

Any help would be appriciated. Thank you in advance.
