BSOD 0x7A, seemingly random

Theblaze973, unfortunately, you have no dump files, which is what we use to debug with. Either your computer did not create them or your use of cleaning tools deleted them which many will do by default, unless those items are deselected.

What seems obvious, is check disk finds errors when there should be none. Yet it keeps finding them. BSODs mentions NTFS file system. The problem, just from your description lies somewhere between the ram and your hard drive. At least that is the first place I would look. Memtest must be run for 8 complete passes before it runs a complete test. It won't run 8 complete passes in 8 hours. Norton is a cause of BSODs. You said you ran sfc /scannow for 3 times with reboots in between, but never said what the results were. So, if you would, please configure your computer for small memory dumps. Make sure you have a C:Windows Minidump folder. if not, create one. Dump Files - Configure Windows to Create on BSOD

Create a system restore point System Restore Point - Create

Next enable Driver Verifier

Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

   Information

What is Driver Verifier:
It puts stress on the drivers, and therefore it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How we know that DV is enabled:
It will make the system bit slow and sluggish.

   Warning

Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there are no Restore points, make a System Restore Point manually before enabling DV.

   Tip

• If you fail to get on the Desktop because of DV, Boot into Advanced Boot Options > Safe mode. Disable DV there. Now boot normally again, and try following the instruction of enabling DV again.
• If you cannot boot in Safe mode too, do a System Restore to a point you made earlier.

Let us know the results, with the subsequent crash dumps, if any.

There is nothing in Windows that would automatically clean out dump files. Disk Cleanup would, if that option was checked as would CCleaner, but they both have to be run manually. If you have any of those Windows optimizers or other utilities that run automatically, they probably would and should be removed from your system anyway. they cause more problems than they solve. If you have McAfee or Norton installed, they might and they are both causes of BSODs in themselves. There are special removal tools for them, but it is very difficult to remove them in any case.

As far as the ram, I really can't say except that ram will occasionally go bad for unknown reasons. With the error reports I saw and what you described, I would look at the hard drive again too as well as Windows Updates. There were references to the NTFS file system and your reports of windows scanning the disks is in many cases a warning of a hard drive going bad.

Driver Verifier is supposed to make your system crash so the dump will catch the offending driver. It would be best to make sure your system will create dump files before enabling it.

If you still have driver verifier enabled, disable it. You may have to boot your Installation DVD or the repair CD. Restore to a previous point, which you should have created before enabling DV. See Option 2 System Restore

you may also want to run Western digital's diagnostic test data Lifeguard for DOS WD Support / Downloads / SATA & SAS / WD Black instructions are there

If that won't work, use Seatools SeaTools for DOS | Seagate

Whichever one you can get to work, run the short and the long test.

There is no reason it should do that. Do you see anything to begin with? Your graphics should work just fine, just like in BIOS. The hard drive is not being used and the drivers are not being used. What happens when you boot from the CD?
