Windows 7: BSOD while idle, Stop: 0x7A

I completed the tests; both HDDs passed the short test and the 250gb passed the long test. Didn't run the long test on the 500gb. Now getting BSOD when booting again, like my initial problem. Cycling power didn't fix this time. It only flashes the blue screen for a fraction of a second, so I'm not 100% sure it's the same error, but it probably is.

Not sure what to do at this point, since I can't even boot to Windows to access the logs.

The Startup Repair utility claims to be fixing disk errors.

Edit: blue screen again immediately after the utility restarted the computer.

Edit 2: as I was about to change my boot order to my DVD ROM drive to boot to a bootable Linux disc, I realized I hadn't changed my storage configuration back to AHCI. This stopped the BSOD looping and I am now successfully booted into Windows. What now?

PS: the blue screen(s) I got before changing my config back to AHCI seemingly did not create dump files

To summarize what I've done so far: chkdsk /f/r on both HDDs, sfc /scannow, SeaTools (long and short on Windows drive, short on secondary drive). It seems none of these utilities can find anything wrong with my hard disks and yet stop 7A happened, with parameter 2 0xC000000E. This is very strange.

There may be some more things, like a bad SATA cable, a failing SATA port on the motherboard, a loose connected cable, a loose/missing screw holding the HDDs with the stand, the file system corrupted on the disc, some backup-restore program monitoring the disc is blocking it, a file system monitoring driver of an antivirus, a virus, the sleep/hibernate settings, and the final possibility that the disc checks failed to do the job rightly.

Open the computer. Remove the SATA and power cables. Get new sata cables and apply them with the other unused ports of the motherboard. Tighten all the screws of the HDDs, in the either side.

If you have any program installed for backup or defragment, uninstall it this time, at least on a test purpose.

Malwarebytes is not an antivirus, it is a scanner. Get a real antivirus. Also scan the system for possible virus infection with the following programs.
Disable hibernate/sleep, also on a test basis.

See how it goes. Two possibilities are untouched here, the file system and the chance factor that Seatools did not do the right job. We will check for those two after knowing the result upto this point.

I leave hibernate/sleep off by default, so that's nothing to do with the issue. I'll do the rest over the next few hours.

TDSSKiller and Windows Defender Offline both came back clean. I haven't swapped the SATA/power cables to my HDD yet. My mounting mechanisms don't use screws, so that's not a concern. I have no backup/defrag utilities. I will note that the blue screen has not happened again. Perhaps it was a freak accident?

Toolless mounting?

Try screws.

haha, maybe, if I ever get evidence that my mounting is causing a problem. I don't think it is. The problem hasn't recurred yet, so I'm not sure what it could be.
