Multiple errors for multiple BSODS (even after Windows reinstall)

Looks liek V2 log collector failed when trying to collect the dumps and dump settings info. Have you moved your personal folders, Desktop, Documents, Downloads, Pictures, etc off the C: drive?

Can you zip any mini dumps you find in C:\Windows\Minidump then upload to Google drive and post a share link here. Also check if there is a full dump available,
C:\Windows\MEMORY.DMP and if it is, zip and upload htta as well. It will be a lot bigger so will take longer.

Thanks.

Meanwhile I've asked Spectrum (V2 author) to take a look at the V2 problem.

You could also try running DM Log collector, see if it has more success getting the dumps.

So far the dumps arren't showing me anything.

I see you have 32GB or RAM but it looks like it's running at 667Mhz. According to the users manual, your board supports:

Memory Š 4 x DDR3 DIMM sockets supporting up to 32 GB of system memory
* Due to a Windows 32-bit operating system limitation, when more than 4 GB of physical
memory is installed, the actual memory size displayed will be less than the size of
the physical memory installed.
Š Dual channel memory architecture
Š Support for DDR3 2000(O.C.)/1866/1600/1333/1066MHz
* To support a DDR3 1866 MHz (and above) memory, you must install an AM3+ CPU
first.
Š Support for Extreme Memory Profile (XMP) memory modules
(Go to GIGABYTE's website for the latest supported memory speeds and memory
modules.)

so 1066Mhz is the slowest speed you should be setting. Try that and see if it makes a difference.

If it doesn't make any difference I suggest using Driver Verifier to see if it shows us anything:

Run Driver Verifier

Driver Verifier-- tracking down a mis-behaving driver.

Following the instructions in the above link will check for problems in all non-Microsoft drivers.

What we're looking for is a verifier generated BSOD with a mini dump that will tell us what driver caused it. If you get a BSOD, rerun the V2 log collector as soon as possible and upload the resulting zip file. Also see if there is a new C:\Windows \MEMORY.DMP file. If there is, copy it to another location then zip it an upload to a file sharing site like OneDrive and post a link to it here.

To check if verifier is active, open a Command Prompt and enter:

verifier /query

If not active it will respond with

No drivers are currently verified.

Follow instructions here to decide which drivers you want to test. 3-5 is a good start. Add 3-5 more ever7y two hours until all are selected or you get a BSOD.

I don't see anything in the first link you posted, just 3 black screens. Is that what you mean?

As for RAM timing, is there a setting for Default? If so try that. If that doesn't help,

Power down the computer.
Remove the power cord.
Open the case and remove the CMOS battery.
Press and hold the power button for 15 seconds to drain the capacitors.
Put the CMOS battery back in.
Plug in the power cord.
Power up.

You should get a message about

CMOS checksum error
press F1 to continue, F2 to enter Setup.

Press F2.

Set date/time/time zone/boot devices and boot priority.
Save and exit, see if it boots.

One of the dumps indicates a problem with AVG. Pleaase uninstall AVG and run with the built-in Windows Defender for now, which is an excellent AV program.
Use the AVG removal tool to completely get rid of it please.

That's disappointing.

Power off then on and when you get to the login screen, in the lower right corner of the screen, click on the Power icon then hold down the Shift key and click on Restart. This should allow you to boot to Safe Mode via Advanced Startup Options.

Boot to Advanced Startup Options in Windows 10

Scroll down to: EXAMPLE: Advanced Startup Options at boot for Windows 10

See if it boots normally in Safe Mode. If yes I would suggest opening Device Manager, expanding Display Adapter then right click on it and select Uninstall device.
When that completes, reboot normally. Windows "should" detect your video device needs an updated drive and install it for you.

See if that resolves the problem.

Do you do image backups to an external hard drive using a program like Macrium Reflect?

If not, do you have any System restore Points?

Don't forget to uninstall AVG. Once you do that could you give V2 log collector a try again and upload the zip file to Google so I can look at it.

Thanks
