hi all,

my PC is acting strange lately, I notice that whenever it's running something (typing, synchronizing email, and even when i open multiple tabs on firefox and they are all opening pages) the screen goes blip blap for a second or two, the image got blurry and the pc freezes, before it runs again normally. On one occasion when I opened 6 tabs in firefox while synchronizing thunderbird and typing something on word the screen went blip blap again, the PC froze and restarted.

at first i thought it was just a mere glitch, but it's gotten worse now.

I checked the memory an I still get plenty of unused memory during the incident, so lack of memory should not be a problem. Can it be that the GPU is the culprit? How should I know what cause this?

Any help is appreciated.

Peter
