HI all, This is my first time dealing with mini-dump files, so please keep that in mind. Im not even sure if I attached the correct files. Ive been trying for 3 or 4 months to figure this out, but have ran out of options. Short breifing: Ive reinstalled WINxp about 3 times, and have pretty much eliminated drivers or software as the culprit. "Have tried video and sound drivers". The BSOD primarily always happen 20-40 minutes after watching youtube videos. (Occasionally when running a virus scan/WMP11 or just sitting idle, as well) Happens with Service pack2 or Servive pack 3. (Have current updates!) Memtest86 ran for 10 or 12 hrs with out any errors. 99% sure no Viruses or Spyware!! Have ran ChckDsk/f/r Have also tried a windows repair, but to no avail. Occasionally the browser im using has encountered a problem and needs to close. Dozens of other possible solutions. Like I said, Ive tried and tried to figure this out, but cant. Sorry to bother you, but any help would be much obliged.
