So, I woke up today to a computer that remains stuck on a black screen with only a cursor on it. I can move the cursor about but can't click anything, can't type anything or perform any other action. I've tried running a CHKDSK (which went fine but didn't solve the problem), running safe mode, last known working state, 640x480, all to no avail. Also tried a system repair but when that window pops up, I get the reverse situation as before - I see everythong but get no cursor, while keys remain unresponsive. So I'm basically stuck. Anyone know anything about this?
