    Hi all,

    My faithful desktop of 2 years has started pushing up daisies:
    I was playing GTA5 when the monitor lost connection to the computer and I had to restart. When I started back up, the message that appears after a bluescreen popped up. This started happening more and more frequently, whenever I started any game, then sometimes when I'd just have Firefox open, then about half the time I tried to start up the computer it'd happen at the login screen.

    I did a Malwarebytes scan a few days before this started happening and it turned up clean, and I haven't changed the hardware in 2 years. I tried updating my video card drivers, to no avail.

    The weird thing is how inconistent it is--I was able to play GTA for several hours last night, then it happened again. Sometimes it automatically restarts, sometimes it doesn't. Sometimes the power light flashes. Sometimes it makes me go through Startup Repair (which never finds anything).

    I have no idea what could be causing this. BlueScreenView says it's a graphics driver about half the time, but not all the time. Memtest86 said the RAM was fine. Any advice would be greatly appreciated.

    I can post SysInfo results and the minidump files if they'd help; I'm on my laptop right now because the system in question is really unreliable.

    Thanks in advance.

    Specs:
    Windows 7 Home Premium
    Intel Core i7-3930k
    8GB DDR3 RAM
    EVGA GTX 470
    ASRock X79 Extreme3

    I ran a SMART test (I presume that's the right one?) on all 4 of my hard drives and they all passed.
    I'm using a GeForce GTX 470, with the latest drivers.

    Thanks for the link! WhoCrashed seems to be reliably saying it's a problem with nvlddmkm.sys, which has pointed me in what I hope to be the right direction. I'll post again if I find a fix.
