Screens turn off for a second??

[xReyn]

Hello Guys,

i recently built my first pc and it is working great! Well that was what i thought... but every now and then, both of my monitors turn of for a second and go back to normal without any visible reason? I am using one older monitor with VGA -> HDMI and a newer one via DVI... i already tried to use both monitors with different connections and mailed my graphics card to the seller to get a new one... can the reason be my psu??? Is 600W really not enough for my build? I don't know and that's why i am here and hope someone of you guys can help me out

As i was waiting for my graphis card to arrive, i used the pc with onboard graphics and never had the issue...

Check your power socket, my dodgy surge protector does this, switch and I instantly get no issues with my monitor, it also allows me to get minor artifacts on HDMi.

Tried that and well... guess this time i had a bad card <.< after using it for about 5 hours total and only 1 hour under "pressure" i had white lines all over the screen and the display shut off after a few seconds... everything works fine without the card. Sent it back to the seller and will get a new one from another manufacturer.
