Can you play for a while or does it immediately shut down when you start a game ??

Can you download coretemp program and report your CPU temps here ??

Also what do you mean when u say "I've change 2 SMPS 250w" ??

Like noble said, let us know what your CPU and GPU temps are. It sounds like it may be overheating. If you can run those games with the side cover removed from your computer, then it is most likely a heat issue.

Also, I've never heard of SMPS. It is probably a cheap power supply. Try exchaning it with something better from OCZ, Corsair, or Seasonic.

Well i play game and after half n hour pc shut down and won't restart and i have to replace my smps with new one. I am taking to expert who can resolve this but i need help in one thing that what i do because this happens 3-4 times with me. I blowed up two psu while playing world in conflict which is of 250 watts and now 700w(Mron). So what do you suggest that i purchase to make it work currently. If you need any information please reply me. Sorry for my bad english. Thanks anyway.

250 watt PSU for your config is very low and it makes sense that you blew those out.

Now if you have bought a 700w PSU and that has been blown as well then I would suggest as hawkeye said you get a high quality power supply.

Anything he mentions in terms of brand would be great (i suggest something around of 500 watts) and even if they seem expensive they do justify their price point in terms of reliability and long term performance.

Quality PSUs are usually heavy to hold (much heavier than crappy ones) and also more energy efficient (80%+).

Also, you may want to take a mutimeter to the outlet you have your PC plugged into and make sure the power is stable at 120v. If you get a lot of brownouts or blackouts in your area you may need to get a UPS, preferably one that has a built in line conditionor.

Sounds like cheap PSU's or overheating. I would definately invest in a good PSU. OCZ is a great choice or take it to someone who can run diagnostics on it to find the issue. it would be better to know sooner rather than later if it's an over-heat issue it could save you from losing the Proc.
