BSOD... Computer keeps shutting off for no reason

Dont use a BETA display driver.

Uninstall it using DDU and then install 14.4 WHQL. See how it goes. Let us know.

Further troubleshooting may be needed depending on the situation.

Mini Kernel Dump does not contain unloaded driver list

Okay so i went to download that Un-installer and my computer went haywire and i got rid of the trojan ... so i am trying another method to uninstalling that beta driver.

Once i complete i will come back with a response.

EDIT: Okay i finished the uninstalling. I am downloading the new driver now.
Once i am finished i will respond with results.
Thanks Again.

EDIT 2: Okay everything is installed and i am using the driver which you instructed and everything is working fine. However, i will need to some gameplay time to see if it shuts down on me under pressure. i will revert back if problems continues.

No, dont revert back to the previously installed driver.

If problems persist, that will mean something else. And the rollback will hamper the troubleshooting process.

If it BSODs again, let us see the up-to-date BSOD logs.

Okay. i didnt revert back to the same Driver. i am still using the same driver that you instructed me to do and everything is working fine and hasnt shut off on me again since. As i have been messing around with some of my internal stuff it seems my comp is over heating as well. which i plan on fixing in the upcoming weeks.

However, i did get another BSOD MiniDump that i have attached below. I am not sure what this one pertains too considering that i actually got a Blue screen this time when it shut off on me.

Thanks in advance for checking it out.

EDIT: I did run a Memtest86 and Ran a few passes and got no errors

How many passes you ran Memtest86+? To get teh result, you need to run it for at lease 8 consecutive passes.

Also, post any further BSOD following the Blue Screen of Death (BSOD) Posting Instructions .
