Hi, im new in these forums and i got a question about my pc. Sorry for my bad english!
Since a few days i started seeing strange colors and lines in my monitor display usually while playing games (rome 2 total war, bf4). Once this happens my monitor turns off and then on. And a error from the nvidia panel appears saying the drivers had crashed or something like that. Sometimes the computer restarts itself. My drivers are up to date. First i thought my monitor was failing (its a tcl 19') because it showed lines as soon as i turned on the pc. But then i changed for an old Benq 17' and its starts fine but then i got all the problems i described while playing games. So the monitor isnt the problem. These issues also appeared once while i was watching a youtube video. Please help me with this! Its my psu? My gpu? Im so confused. The temperatures are fine. All around 25-35 Cº.
My specs:

Windows 7 64-bit ultimate
i5 4570
ASUS h87-plus
8gb ram kingston
ASUS Gtx 550ti (2 years old)
1tb western digital
600w coolermaster extreme plus

Except for the video card, all the other components have only 4 months of use.

Many thanks!
