It boots up normally, BIOS and POST are both fine, the Win 7 logo screen appears as it is starting, then goes to a black screen. No blinking cursor, no mouse pointer, nothing. Ctrl+Alt+Del does nothing. My computer should boot in to the login screen.
The monitor is still on (seen by the blue status light) meaning it is getting a signal.
When I restart I get 'Startup Repair', which runs and fixes nothing. I also tried System Restore to a point from a few days ago, still nothing.
I haven't installed anything new in weeks.
Right now I am running the Windows Memory Diagnostics Tool, I will post back the results shortly.
My PC is:
OS: Windows 7 x64
CPU: AMD Phenom Quad Core 2300mHz
Graphics: ATI Radeon 5450
MB: Asus M4A78 Pro
