My computer has gone downhill very quickly over the past two weeks. I haven't really done anything drastic to it and have no idea why it's running so slow. I know this is incredibly vague, but I have no ideas. The computer lags when I only have one or two programs running(I have 768mb of ram on a 2.8ghz processor) Simple things like clicking a hyperlink or opening a folder take as long as 30-45 seconds to perform I have run many different spyware hunters, defragmented the computer and run chkdsk. Any other programs recommended? Anything I could do to attempt to locate a problem? I have no ideas. Thanks in advance.
