As my new boss says: "Use Unix forget Bugdows"
Or, the very least, don't use the $hitty Internet Explorer. Since I started browsing with Mozilla Firefox I've never had internet related problems (unless routers get too busy).
Another problem might be - viruses or spyware. No reliable cure against them.
Format C: helps in most cases (I've done it twice since I got my computer - it worked). This would help only if you had considered dividing your hard drive in two or three and preserve your important data on d:
Mine is divided c: 15GB/ d: 65GB - never had problems formatting c: and reinstalling windows as disk d: is the data disk
