I was working on my boss' spare computer and was running CleanUp when his computer went into Hibernate mode, which I was never able to get it out of. Upon reboots, the normal startup process begins with the Windows screen loading, ect. After that, all I get is a black screen with a mouse cursor that I can move around, but no other functionality. Ive rebooted in Safe Mode, SM with Command Prompt, and from Last Good Config and get the same result each time. Any ideas on what I should do from here?
