I think my computer has a hardware problem. It's a 5 years old Dell XPS 8100, the same one which had shutdown problems 3 months ago (by the way, those problems just stopped happening, magically I guess...).
3 days ago, I had a blue screen crash. When it happened, I was just watching some livestream video in fullscreen mode, on Google Chrome x64, using the built-in Flash plugin. The video was playing just fine, and the next second, with no warning at all, the screen went blue, it started saving the dumpfile, finished, and rebooted itself.
The error code in the Windows event log is 0x0000001e (0xffffffffc0000005, 0xfffff800030a331a, 0x0000000000000000, 0xffffffffffffffff). Quite helpful, right? Google took me to this forum thread so I downloaded BlueScreenView, which applied to my dumpfile, shows this
Still not quite helfpul, really, the bug check string couldn't be more vague. Anyway, since it seems this might be a hardware problem, I downloaded the latest memtest86 version and created a bootable USB stick.
That was yesterday. Today I've booted the PC directly into the USB, and let it run the memtest86 with the default settings. Please note it's memtest86 v4.3.7; apparently my computer doesn't support the newer one.
The first time, it has taken 41 minutes to complete all the tests, and found 0 errors. I've read that it may take a few sweeps to find problems, so I've let it continue running for the second time. After around 1 hour more, it had completed 40-45% of the test (it seems to take more iterations the second time), and... the computer just rebooted itself again!
I don't know what to think. Am I having power-supply-electrical-whatever problems again? Was that a memory problem? Did the program just crash? It didn't show any message or anything, and the found errors count was still at 0.
What can I do? Is there any way to diagnose or further analyze any of these problems?
