Why do my games keep crashing

  1. About a year ago i built my computer and had no problems at all. Maybe 6 months ago i started having trouble with my games, i would start to play when all of a sudden the screen went to some weird screen with vertical lines of usually 2 colors going down the screen and whatever sound was being played in the game would loop and play over and over. Ive probably spent more time troubleshooting then actually playing games these last few months, im pretty sure ive tried everything. Things ive tried:
    Increasing the fan (not a temp problem)
    reinstalling graphics card
    overclocking in any and every way you could possibly think of
    cleaning all the dust out
    running torture tests (no errors)
    switching monitors
    check my power supply (its plenty enough)
    and a few other things

    For about the last month i havent had any issues at all but now all of a sudden the crashes are coming back. i havent changed anything or done anything different so im not sure why.
    Games it Happens to: CODMW2 , Mass Effect 2 , Borderlands.
    Games that work: Assassins creed , ETQW , FO3 , L4D2

    I noticed that all of the games that dont work i got on steam, could this mean anything? but l4d2 was also purchased through steam but it works.

    System Specs:
    AMD Phenom 9950 Quad-Core Processor 2.60 GHz
    8gb ram
    Windows Vista 64 bit
    ATI Radeon HD 4850

    Im really confused and would really appreciate any help.

    What driver set are you running? Catalyst 10.1 is the latest I think.

    Is DirectX up to date? What happens if you try to run games in DX9 mode?

    I wouldn't try messing with the clocks unless you're looking for additional problems. If the card doesn't work well on factory settings then it's rarely worth your time to experiment with clock speeds. Vertical lines can point to faulty video memory, and although you may not experience problems in some games, the card may be going south.

    sometimes when i run into problems running games in DX10 i will try to run them DX9. you should be able to force games to run in DX9 by adding "-dx9" to the end of the desktop icon target string (without quotes). some games even have the option available from the Start > Games window, so you can right-click the shortcut and select it.

    just right-click the desktop icon shortcut and select Properties from the list that appears. in the windows that pops up you should see a field that reads "Target" and there is a path where the executable file is. all you need to do is add -dx9 to the end of that path, and after a single space, and the game should run in DirectX 9.

    Could you specify the make / model of the PSU.

    Also, if the system is crashing I would advise you not to OC the processor. Have you considered reinstalling Windows after a clean format?
