monitor switches off only during gaming

Hi everyone,

I bought a new pc back in may my pc specs are:

Core 2 Quad Q8200

4 gb ram

nvidia Geforce 9800 GT 1 gb Galaxy

ok so here's the problem, last month my previous PSU which was 550 Watts got spoilt and my pc wouldnt turn on. So my engineer put a new 600W PSU but ever since, my monitor switches off ONLY during gaming. I hear the CPU going off for a brief sec (but it isnt since the lights are still on) and then i hear it running again but the monitor is switched off and i have to then manually switch the comp off by holding the power button and restarting it again. It happens with every game right from 2005 games like scarface to the most recent ones like Bioshock and Arkham Asylum etc. I heard that the 9800 GT 1 gb card requires 26 A on the +12V. However i checked my PSU and there are 2 +12V values where the first +12V has 14 Amps and the second +12V has 8 amps & there is also a -12V which has 0.8 Amps. So what is causing the problem?? Is it the PSU?? The company name of my PSU is SURE. I hope it isnt the graphics card since i cant afford a new one since here in my country they are expensive. Any help will be appreciated, thanks

no it does not show "no signal". ummmm it switches off and the light on the monitor starts to blink for eg: if you keep your comp on without doing anything for a long time, your monitor goes to sleep, its similar to that.

so, did you ever tried to switch off your moniter for a while and then switch it on.

what happens ?does it show output or no response as previously.

if it responses then there could be a problem in the filament of your monitor.i guess so.

I've had that also well kinda, it switched of during everything.. I got it fixed by reseating my video card.
