Windows 7: Random BSOD 0x0000007a and occasional freezes, more often lately

Hi,
I'm a little out of ideas here, and since I don't know how to read the error dump files properly, I suppose this is the place ask.
I'm getting frequent (1x day, far more than previously) BSOD with error code

0x0000007a (0x0000000000000020, 0xffffffffc000009d, 0xfffffa8007e62078, 0x0000000000000000).

I've already done chkdsk /r /f (no errors) and a memory test (no errors).

I've attached here the zip file from the posting instructions as well as a msinfo32.nfo zip, in case that helps.

FWIW, I'm using Bitdefender as Antivirus, but it occasionally complains that its service was stopped and needs a reboot,for no apparent reason. I'm not sure it's related but maybe worth mentioning.

If you need any more information, I'd be happy to try and provide it.
Thanks,

Rafael

Hello rafaelsend and welcome to 7Forums!

Could you please open up a new Windows Explorer window by pressing:



and paste this into the address field: %SYSTEMROOT%/minidump and hit enter. If you find any files there please upload them here!

Thanks in advance!

Cheers, Boris

Hi Boris-
Checked, that directory is empty...

Well crap.

Hmm, this will be quite hard to troubleshoot without those files.

Could you please read through this and assure that you have everything in order:

Dump Files - Configure Windows to Create on BSOD

Oh and you aren't by any chance using CCleaner? If you are, then please stop as CCleaner has an option to delete minidumps from Windows(why).

Cheers, Boris

Please check in the BIOS that the disk is seen in the list of bootable devices.

I don't assume you still have warranty?

axe0- Disks detected fine, that's never been a problem. Warranty? Lol. I've made so many modifications to this machine that I wonder if it even still counts as an X61

Boris- You're correct, nice catch. I do indeed have CCleaner set to run on startup, no wonder all the logs were always gone. But not to worry, it's crashed again since, so I've attached a zip of the requested minidump file.
Thanks!

Please check that the cable of the hard drive is properly connected and not damaged.

Is a STATUS_DEVICE_NOT_CONNECTED, caused by a damaged or improper connected cable, termination or that the controller cannot detect the hard disk
