BSOD: error 1a after playing 2 games of LoL

98 Percent chance that after 2 games the PC will crash. If I get lucky the 2 percent will prevail and it will crash in the 4th game. After the crash the PC will not boot and will just flash No Signal in the monitor after 5 - 24( if I also get lucky it will boot 5 hours after the Crash)

The trap frame for the exception shows that a Divide Error has occurred, which is usually caused by device drivers. Yet, the bugcheck suggests a illegal page fault has happened during working set synchronization. There is some synchronization present with the release of a queued spinlock in the raw stack.

Start Menu\Programs\Registry Easy

Windows 7 doesn't require any programs which make changes to the operating system and registry, these programs tend to cause problems by modifying and deleting files.

• Registry Cleaner Tests - Why NOT To Use One!

Windows is a closed source system. Developers of registry cleaners do not have the core code of Windows 7 and are not working on definitive information, but rather they are going on past knowledge and experience. Automatic cleaners will usually have to do some guesswork.

Modifying registry keys incorrectly can cause Windows instability, or make Windows unbootable. No registry cleaner is completely safe and the potential is ever present to cause more problems than they claim to fix.

Registry cleaners cannot distinguish between good and bad. If you run a registry cleaner, it will delete all those keys which are obsolete and sitting idle; but in reality, those keys may well be needed by some programs or windows at a later time.

Windows 7 is much more efficient at managing the registry than previous Windows versions. If you run any other registry cleaner and do not know precisely what you are doing, you will have problems down the road. There are no gains to be had from using a registry cleaner and the risk is great.

Run Driver Verifier to scan for any corrupted drivers which may be causing problems, this program works by running various stress tests on drivers, in order to produce a BSOD which will locate the driver; run for least 24 hours:

• Driver Verifier - Enable and Disable

Then here comes another problem , my PC now freezes less than a minute(5 - 30 sec) after the welcome sign. Even in Safe Mode. Then after that the PC will not boot

Boot into Safe Mode with Command Prompt, and then type the following command:

Code:

verifier /reset

Reboot the computer, and then attempt to boot into Windows normally. Driver Verifier should be disabled.

Update your System Specifications with Speccy, and then copy this information into your System Specifications: Go to your UserCP, and then select Edit System Spec in the left pane. Copy the information from Speccy into the required fields. These System Specifications will then follow your every post.

I'm sorry for my 2nd reply(It's incomplete). The PC freeeze at the startup before I even download and use Driver Verifier

You don't need to download Driver Verifier, it's a in-built tool for the Windows operating system. So you can't even boot into Windows normally or within Safe Mode in general?

Troubleshooting Windows 7 Failure to Boot

I can boot in both modes but it will freeze after Windows loads (approximately 5- 30 sec after it loads) then the PC will flash a "No Signal" warning then black screen.

Miraculously, I managed to run Driver Verifier and got 2 Different BSOD's at 4 different restarts and boots. 1A and 10000008e.fI already disabled driver verifier to stop the BSOD's. Here are the minidumps.

The exception which couldn't be handled was caused by a NMI (Non-Maskable Interrupt), which usually indicates some form of hardware failure, however, looking at the stack we can see that avast! seems to be causing problems. Furthermore, generally all the dump files tend to indicate something related to graphics, which may explain the loss of connection between the monitor and graphics card.

So here's what happened.
After I booted into Safe Mode and uninstalled avast!(I used the Avast Uninstall Utility). I restarted to Normal Mode and tried to play LoL to check if everything's normal again. My PC did not froze until champion select. I was waiting for a BSOD but it never happened and it stayed frozen. I turn off'd the computer by holding the power button and I cannot reboot my PC. Now I'm waiting for my PC to boot again and to check if there are dump files
