When I booted up the computer this morning, I noticed that the resolution was changed from 640x480, when i had it previously set at 800x600, as normal. Then after start-up, there is no mouse and the computer crashed. I tried booting in safe mode, but it also crashes after start-up. This has happened to me twice now and both times I had to run a user restore, thankfully all my files have been backed up. But I simply cannot understand why this is occuring.
