frequent BSOD 0x01e 0x050 0x0a, while idling; minidump

My system is fond of BSODs right now. I'm getting 0x01e, 0x050, and 0x0a blue screens, even while the computer idles, which is what it usually does. I occasionally get other stop codes, like, wow, right as I was typing this sentence, 0x07f.

Analyzing dmp files is beyond my windows skills, so my sincere thanks to whomever takes a look at whatever's going on with them.


System...

Windows 7 Ultimate x64
ASUS M5A78L-M LX (AMD)
Nvidia GeForce 430


Stuff I've tested...

-- Not the RAM. Memtest passess. 6+ passes, all 100%

-- Not the videocard. Still get BSOD when it's removed. (There are no other cards.)

-- Not the power supply. (And power supply is definitely hefty enough.)

-- Not anti-virus software.


Assorted infobits...

-- Motherboard/CPU are about 18 months old, have stayed clean and all fans work.

-- BSODs appear regardless of CPU load, which is usually very low.

-- Videocard is a Nvidia GeForce 430, with a working fan. It's not a hot monster.



Troubleshooting...

-- I don't know when I started getting these infernal BSODs. I rarely install stuff on this computer, so it's not like the BSODs started after I installed something.

-- When I first used driver verifier, I stopped getting BSODs and just got black screens of death instead. So, I rolled my NVidia driver back to 337.88, clean install. It was previously at 340.52. With the 337 driver, the black screen of death (after starting driver verifier) stopped, and I finally got a BSOD and then collected the minidump (attached).


Thanks much.

UPDATE: Even in "Safe Mode with Command Prompt" I'm getting the same BSODs.

What's a good liveCD that I can use to test the hardware and/or wait for wait for it to crash/not crash?

UPDATE: It was bad sata cables. I guess they just wore out from all the awesome data I was transferring through them.

I found some random comment somewhere that happened to stick in my brain. According to this random lifesaver, the cables that ASUS ships with their motherboard are pretty weak. New cables = no more BSODs.
