0x124 BSOD while watching online flash videos.

[Citizen Krang]

In the last couple of weeks or so I've started getting BSODs while watching flash videos online. It doesn't seem to matter where they're from I don't believe. It's also not a guaranteed thing with any given video, it appears to be at random but if I had to guess it takes maybe a half hour total of flash video viewing before it happens. I updated all the drivers I could find that could be updated. It has yet to happen any time that I wasn't actively viewing a flash video.

All 4 crashdumps report WHEA errors specifying that your CPU's L1 cache is experiencing problems. While this immediately makes me think we're dealing with a hardware issue, that's not always entirely true with WHEA errors like this, though it is very suspect. I recommend you update your BIOS and your chipset drivers for your motherboard, and if you have any software that came with your motherboard, uninstall all of it (probably need to use the free app Driver Fusion to get rid of em entirely). Often times I've seen motherboard software do funny things that actually cause hardware-generated WHEA errors like this. They are not recommended. Only update and keep installed drivers specifically designed to provide functionality to your motherboard devices. Anything more is superfluous, gimmicky, and bug-ridden.

If none of that works out, I recommend doing an overnight run of Prime95 on Torture Test with Large FFT settings. Make sure your CPU cooler is sufficient as it will push the CPU to its maximum limit. If your system crashes or the test fails (it runs infinitely until error or manual stop), then your CPU's L1 cache is very likely bugged, and you must replace the CPU.
