Well, I have a major problem.
I installed that CD burner sucessfully. Everything was going well....
Until yesterday. My sister used the PC, and got a STOP error. Also, the PC has slowdown. I noticed I got a worm as well, since I saw a process called microsoft.exe, which is a worm.
My sister rebooted, and during the black and white "Starting Windows" screen, it loads for a second, and stops.
What could be causing the problem?
