    Hi,

    I'm having a strange problem with my 295. I've been running it fine now for 4 months, but last week I started getting random freezes. To begin with a thought it looked like a hard drive problem, but no. I then realised I'd updated my drivers about 4 days before. So I uninstalled all my nvidia drivers and left the PC running without any for 4 hours, and no freezes! I then went back to the 190 drivers (from 195) but I was still getting crashes.

    The freezing leaves everything on the screen but the computer is completely unresponsive. Yet, sometimes, my music continues to play.

    After some thinking I thought maybe it was a temperature problem. So I played a little CoD MW2 and temperatures didn't go above about 75oC which should be fine, but STILL it froze. :bang: However, I still had the nagging feeling it was the card. I set the fan to 100% and now I'm getting no freezes... But it's not really a solution, it sounds like a jumbo jet :p

    Am I dealing with a dying card? :( It'd odd because I've always been careful and it's never gone above 80oC. Shame.

    hello
    i guess you nead to open and clean it up
    also,you might want to replace the thermal paste with new one

    all 2-in-1 gpus owners ,we are coursed by the temp issues

    also, make sure the airflow in the case its good

    Hiper 580w

    I understand this is below the minimum but I checked out reviews and they all logged well below that with better hardware and overclocks.

    If it was a power issue I'd assume it would happen under load, however the freezing occurs at the windows login screen sometimes too, or just when it's sat on the desktop.

    It's airflow I think, after taking the side of my case it's all good.

    Doesn't really matter if you think 580w is too low, it isn't. It's like people that get over 4GB of RAM when most games don't go over 3GB.

    580W isn't too low, but it's definately pushing at the threshold and it will be taxing on your PSU. Overhead is a good thing when it comes to PSU's, as the more you max it out, the less efficient it becomes at delivering stable clean power.

    Keep in mind that the TDP of the GTX 295 is nearly 300W, Your CPU when overclocked will be well over 100W, then factor in the rest of the components that have to run off your PSU and you're left with no more power overhead. Your PSU doesn't produce 580W on the 12v rails alone and then you have to factor in the inefficiency of the unit.

    In this case, it would be a very good reason to blame it on the PSU, but it's good that you've solved it by other means.

    mine draws nearly 500w from power outlet with prime95 + occt gpu burner

    think i could go over with clocking a bit


    make new install on other partition with drivers u know works, might be fastest way to see if its hw or sw

    I get that every once in a while too I just figure it's driver related.
