No joke, the problem started when I replace my pc2100 128mb RAM with pc2700 256 RAM. At first nothing was wrong, but after a couple of days, the computer barely worked at all. It was so slow. I talked to dell, and all I got was that I might have spywares issues. I've taken out the pc2700 RAM and placed the 2100 back. But the problem persists. Can anyone tell me if it is a hardware problem or software? Would reformatting my harddrive help?
