Sometime's when i start my computer, and after windows load screen, my monitor turns completely black like there wasn't any cable inserted. It doesn't say "No signal" or anything, its just black.
When i then click the power button, waits a few seconds and turns the screen on again, the desktop gets showen in 5 seconds and it then gets black.
If i the switch my cable from the 1. DVI Out to the 2.(Or vise versa) it works absolutely fine.
My monitor is a Acer AL1711 LCD wit standard VGA cable, with a VGA to DVI converter. My GFX is a Geforce 7950GT 512 mb.
I am 99% sure that its my gfx card.
Also, now when i have turned my computer on for like 20 minutes i guess, havn't been in any games and i have only got IE opened so far(and standard startup programs ofc.) the GPU temperature is 56 Celsius! (SpeedFan)
Is my GFX broken or something? I havn't changed any cooling devices or anything since i got my machine (May 2007).
