So this started a few months back, and now its really getting on my nerves.
My System Spec
AMD Phenom II X4 955
4GB DDR3
ATI Raedon HD7770 1GB DDR5
Psu - 550W
OS - Windows 7 Ultimate (32-bit)
The situation :-
Whenever I try to boot my PC, everything is fine till the "Starting Windows" logo. And after that the screen goes black. I don't see the welcome screen.
I DO NOT have any mouse cursor. I CAN NOT run task manager. But my PC is still responsive - I can hear the welcome sound over the speaker, and also my keyboard works (turned the num-lock key on/off).
Then I hard-restart the PC. Usually it would run just fine, at least it used to when the problem first started. But now I have to restart multiple times, and at some point, it would boot without the black screen.
I can always boot into Safe Mode without any black screen.
I don't think its the PSU, as I have this same system config for about a year and this problem started just a few months back.
Things that I've tried :-
1. Checked the registry value (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\shell). Its value is "explorer.exe" as expected.
2. Entered safe mode. msconfig. Disabled all non-windows services. Completely uninstalled the display driver. Still getting the black screen on normal boot.
3. Reformatted/reinstalled a fresh copy of Win7. Installed no driver and nothing. Shut down. Reboot. Still no joy.
4. I turned on Base Video in msconfig while in safe mode. And now i can boot normally, with crappy graphics. So this must be something to do with graphics driver, right? But i am using a fresh copy of Win7 right now, w/o any drivers!
So experts, please help!!
