I built my PC about a year ago. It has a Pentium D 805 overclocked to 3.3ghz, 2gb or DDRII 667mhz ram, and a ATI X800 XT AGP card. It has been running awesome. The dual core flew through everything. I used to be able to do so much at one time. I could encode a DvD, have a Game playing, browsing the web, have ventrilo going, all at the same time. Now all the sudden if I even try to surf the web when encoding a DvD it is sluggish. What could that be a symptom of? Could the CPU be going bad? My hard drive is defragged, I keep my disks cleaned up. Always on top of the spyware removal and antivirus. Thanks for the help.
