Perry's computer is driving me nuts

Perry's PC has been unstable ever since it was built. I have replaced:

Memory
GPU
Power Supply

Through ALL of these iterations, it is STILL unstable.

During video activity (as far as I can tell), it will blue screen and auto-reboot. It's not consistent insofar as it will happen randomly in different spots in a game, or even during Skype video chats. I thought maybe replacing the GPU with a lower power one would help; it didn't. I've tested the RAM with Memtest, and it passes.

A couple of years ago, I thought it was voltage (so did Ryder). We got some different RAM in there and it still crashes.

Blargh. Ideas? I'm about to run a thorough CHKDSK.

    Not many components left to suspect, know what I mean?

    Malware check?

    Yeah, try a long thorough chckdsk also.

    BIOS reset to default values, then change what you know you need to (SATA to AHCI, time, boot order, etc).

    OCCT for CPU/GPU stress testing (Furmark also works well for GPU).

    Complete OS reinstall?

    I reset BIOS values to default and now I've bumped up CPU voltage a bit. Grr.

    Bumping the CPU voltage up 0.1v seems to have begun to solve the problem. How would a normal person ever fix something like this? Sheesh.

    Thats why you have a forum full of "abnormal" people :-)

    This is exactly why I've soured on custom PCs in the last few years. I remember a time when it was damn near impossible not to end up with a rock solid system with any combination of half-decent components. Now, there's all sorts of little quirks with every single component, permutations that should work but for some reason don't, etc.

    How did a CPU that can't run stably at stock voltage get out of the binning process? Or did the motherboard maker put out a board that supplies .1v less than it thinks it's supplying? Or is there an undervoltage situation created when the video card starts cranking up?

    Either way, it's reasons like this why I don't bother building stuff from scratch unless the client is playing with a decent budget.

    His computer's been stable all day. League of Legends was the game that crashed the most often for him; he played it for two hours today with no crashes. I guess I just needed to say it out loud for me to be able to fix the problem :p

    I've had issues on AMD systems running with all four memory slots occupied. A little extra juice to the CPU and RAM normaly solves it.
