My computer, operating on Windows 98 has been freezing up lately at the touch of a mouse. I can no longer access the internet. When I attempt to run Norton AntiVirus, the program cannot find the boot log. When I attempt to shut down the computer, it freezes after displaying a message that a program is still operating - although it doesn't give the name of this program. At this point, I can only get it to boot up 5/10 times. The last thing I want to do is reformat my harddrive (considering it's a homebuilt computer). I'm wondering if this problem is familiar to anyone? Could a virus have infected the base code? Again, any help is appreciated.
