full screen video glitch

[phantomtrooper]

sometimes when i watch full screen video over the internet the video gets scrambled but the sound keeps working, then my computer locks up, and i have to reset it. my computer specs are as follows.

asus p5n-d 750i
2x 1gb corsair xms2 in dual channel
evga 9800gtx
500gb hd
intel e8400

does anyone know why this happens or how to fix it? i have the latest n-force and graphics drivers. the glitch only happens when i watch full screen video over the internet. it never happens when i watch dvds or video on my computer. i use internet explorer. i havnt tried firefox to see if it happens on it as well.

i personnally think this could be your graphics card, faulty memory or HDD, or Overheating, its hard to tell, but one thing is for sure your in the wrong section, if you want a proper answer i would try the CPU & Components section of Toms Forum, http://www.tomshardware.co.uk/forum/forum-10.html
