Hi, For the past month now, I have been having BSODs. I usually have them randomly while using my computer but I also have them in Overwatch. The name of the BSOD is either APC_INDEX_MISMATCH or IRQL_NOT_LESS_OR_EQUAL. While in Blue Screen Viewer, I can that the File/Driver that is causing it is my ntoskrnl.exe.

I have tried reinstalling Windows 7 but that has not worked and I am wondering if anyone can find the problem exactly.

If any additional info is needed, don't hesitate to ask.

Thanks for your time.

I have tried to remove all of the drivers installed by this. I have still been getting crashes and BSODs. Also want to mention that I have been receiving BSODs long before Driver Booster 4.

Driver update utilities are known to affect troubleshooting and stability, also when used after the first time issues occured.

Removal of the utility wasn't a suggestion to fix the BSOD, rather to prevent issues with troubleshooting.

If you want to post about BSOD issues, please follow the BSOD Posting Instructions. Without logs I cannot help.

Read carefully before proceeding.

   Warning

If you're overclocking your system, revert back to stock clocks now.

   Note

Test the system once the overclock is removed before continuing with the steps outlined below.

Part One: CPU Stress Test
Part Two: MemTest86+ RAM Diagnostic
Part Three: Hard Drive Diagnostics
Part Four: GPU Stress Test

ONE

 CPU TEST

Run Prime95 and/or IntelBurnTest to stress test your CPU. Prime95 - Stress Test Your CPU - Windows 10 Forums & CPU - Stress Test Using IntelBurnTest - Windows 7 Help Forums

   Warning

Your CPU temperatures will rise quickly while under this stress test. Keep a keen eye on them and abort the test if overheating occurs.

Make a photo of the result and post it.

TWO

 RAM TEST

Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 7 Help Forums

   Note

MemTest86+ needs to be run for at least 8 complete passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

Make a photo of the result and post it please.

Addition:
If errors show up you can stop the test, remove all sticks but 1 and test this single stick in each slot for 8 passes or until errors show, switch sticks and repeat.
If errors show up and you see them a lot later, no problem, the errors don't affect the test.

Diagnostics Test

 HDD TEST

   Note

Please run HDTune first, in the order posted!

Run HDTune to

• check the health,
• scan for errors, no quick scan but full scan
• run a benchmark.

It may take some time, but please take the time you need to perform it properly.
When above is done please make screenshots of the following

• the health,
• the error scan,
• the benchmark incl. following
  • transfer rate,
  • access time,

Next step, BIOS and drivers

Check for BIOS updates and reset the BIOS to default settings.

Diagnostic Test

 DRIVER VERIFIER

   Warning

Please make a backup of your important files and get your rescue media or create one.
Please create a restore point.

Please follow this tutorial to run driver verifier.

Driver verifier stresses your drivers and will crash your pc if any driver fails due to a violation.

Driver verifier should be performed for a max of 48 hours, or when you have a bluescreen, whatever comes first.

If driver verifier has found a violation and you can't get back into windows normally, try to boot into safe mode and reset in safe mode driver verifier, or in the troubleshooting options open command prompt and type verifier /reset.

   Note

Your system will act very sluggishly while driver verifier is enabled, this is normal as your drivers will be being subjected to heavy testing in order to make them crash.

So I first found out that there was a bios update that I had not installed. At first i thought it was the problem. But I still experienced a BSOD occasionally but definitely not as much as before.

Then I ran the Verifier test and I would experience the BSODs before logging into my computer (During Startup). So here are my dumps. Thanks again!

Note: I ran the Verifier test today, 6/19.
