Is my Intel i7-2600k processor overheating or do I have an issue with my graphics card?

Recently I got an Intel i7 desktop computer. Whenever I play NFS HP or BLUR, after 2-3 hours the screen starts to flicker. The problem is fixed when I restart the computer, but after half hour or so the screen starts to flicker.

I had installed CORETEMP software. It used to popup again and again. However, in load window it used to show only 3-4% and temp of each core was not more than 45°C. tj.max was 98°C.

Also while using AUTOCAD 2009 I am getting an error saying “DISPLAY DRIVER HAD STOPPED RESPONDING AND HAS BEEN SUCCESSFULLY RECOVERED” and then it says that the program is not responding.

I have already installed latest graphic card drivers. I don’t get which component is malfunctioning CPU or graphics card?

Windows 7 64-bit
i7-2600k processor
Asus 7770HD graphics card
4GB RAM

    Ajinkya, a 500 Watt PSU is probably enough (can't be definite as it depends on the graphics card as well, but in all likelihood that's not where your problem lies). If your current PSU is acting up, however, then the only reliable way to diagnose is to try another (tested and good) PSU.
    Jim Chambers' suggestion also has merit, and might be easier to carry out first!

      man i think its bcoz of PSU only, the PSU is having the fan on the top...and my cpu cabinet is not having any opening from the top....so now i have turned the PSU upside-down now the fan is facing downwards inside the cpu...but i think it will heat cpu from inside....CAN PSU HEATING CAUSE SUCH PROBLEM...

      An electronic component is prone to fail if it gets heated.If your PSU is not cooling its parts properly and is under warranty,then you must ask for replacement.

      Secondly,the fan is intended for cooling purpose only,so,you must not place it downside as how it will throw hot air ?

      The PSU fan draws air out of the case so it will help to remove heat from the CPU and GPU. The initial orientation was incorrect and may have resulted in damage to the PSU. Do you also have a rear case fan that pulls air out of the case?

    Since you installed the new drivers, has it still been giving you the Autocad error message? I had a machine that would give me that message. when I mailed tech support for the game it did it on, they said I needed to use Legacy drivers for the GPU.

    Good luck with your error....

    Sounds like your GPU is overheating. Replace heatsink compound with quality brand and check that fan turns freely. May need to add a larger or a second case fan to increase cooling.

    Can't be sure, but it sounds like a power supply problem. Power supplies often "half fail" resulting in components start-stopping and the sort of behaviour you describe. If you can borrow a good power supply (make sure it's strong enough, i7+graphics card will need a fair bit of power!), then try the other PSU and see if it works any better.

    you can use the virtualized "XP Mode

    concerning games you should meet the requirements

    then you should check the driver, go to device manager locate the graphic card driver then right click on it and choose uninstall (do not delete) the reboot and let windows to install the driver.

      i ve checked for both the games on game debate...it says i can run it...moreover its saying i can run 99% of the games present...so there is no problem with requirements and my friend is also running autocad 2009 on win7 64bit....i think its hardware problem graphic card or cpu...bench ratings are also good....i m getting 1356 on novabench

      have you tried to update the video card driver or to use an older to see if it will help solving the problem.

      go to BIOS and disable onboard graphic card

      if PSU is faulty and do not deliver right amount of power, yap it can cause problems and normally nvidia or ATI should popup a message telling you that the graphic card needs more power.

      there are two types of power supply: Active PFC and Passive PFC
