9600gt issue plz help

Sounds like either your GPU is overheating, or there's a driver problem. If those two aren't the issue, your GPU may be bad.

First thing I'd check is to see if the same thing happens in other games/software. It could be a drive conflict with the particular game/software.

You might try installing an older driver to see if the problem goes away. And then check your temps on the GPU.

If temps are good, different drivers don't help, power is determined not to be the issue, and the same problem appears in multiple games, you may just have a defective GPU.

The power supply looks like a winner...( and I don't mean that in a good way ). There were some issues with over clocked cards. Did you try and under clock it at all ? Which one do you have ?

I'd imagine your power supply isn't helping. Not familiar with that brand, but look at its specs, they don't actually give the 12V amperage. It only says, "10A res max. for 115VAC". If it only had 10amps on the 12V rail potentially, that's not going to work for you.

damn are you sure ? Can you recommend me the cheapest psu that would be sufficient. like i say in my other post a friend has the exact same psu with a more powerful gfx except he has no issues

any 500w psu from corsair/enermax/antec/ocz will do. afaik they dont sell underpowered volt-rail products.
