BSOD Occurs Randomly - hwpolicy.sys

Hi Guys,

I have a custom built pc with the spec listed below:

--------------------------------------------
AMD Athlon 64 X2 5200+ (Socket AM2)
Asus M2A-VM HDMI
ATI Radeon X1250 (Built in)
Realtek Sound Card (Built in)
6GB RAM (2x 2GB & 2x 1GB) - DDR2
Windows 7 Professional x86 - SP1
--------------------------------------------

FILES:
Attachment 330561
Attachment 330562
Attachment 330563

MINIDUMP:
Attachment 330564

**EDIT**

Here is the link for all the BSOD Data from the SF Diagnostic Tool: Attachment 330599

The computer keeps BSODing whenever i open the browser or install something, i have attached the latest minidump file along with screenshots of the system spec. I recently did a clean install of windows on the pc and that fixed a few of the other BSODs i was having. I have used Bluescreenviewer to read the minidump file and it has told me that hwpolicy.sys and ntkrnlpa.exe was causing the BSOD.

I have gone through many articles on Google but cannot fix the problem.

Anyone have any idea on what it could be? I'm not great at analysing minidumps so i have attached it for your information.

Thanks

Welcome MistUnleashed .

Welcome, please follow the Blue Screen of Death (BSOD) Posting Instructions .

Although I don't have much information I have a feeling we are dealing with an infection,
do you believe that kind of scenario is possible?

Hi YoYo!

I'm just about to run the SF Diagnostic Tool!

I will post the file up when I have done it!

Infection wise I think its highly unlikely as I have run numerous virus scans and boot-time scans using Avast! and they have come up clear.

I think its a corrupted driver problem, but i may be wrong!

Thanks

Hi Yoyo155

BSOD Diagnostic Files: Attachment 330598

Files are attached and I have updated my original post with them.

Please let me know what the problems are and advise on how to fix them!

Thanks!

Hi thanks for the files, although many of the files are missing I can see you have a pretty
old machine with a BIOS dating way back in 2007, two years before Windows 7 went RTM.
I can also see you have an assortment of memory modules.

The BCC (bugcheck codes) vary greatly, so the best place to start would be testing the RAM.

Testing the RAM:

Tip   Tip
  • Pay close attention to part 3 of the tutorial "If you have errors"
  • Test the RAM with Memtest86+ for at least 7-10 passes. It may take up to 22 passes to find problems. Make sure to run it once after the system has been on for a few hours and is warm, and then also run it again when the system has been off for a few hours and is cold.
When done with the testing procedure take a picture and upload it here.

This will help you to determine where the issue is origination from (if any):

But if it starts showing errors, Stop testing. Errors/red lines means one or more RAM is faulty. But the fault may occur due to a faulty DIMM slot, too, which is a motherboard component. Using memtest86+, you can discriminate between a faulty RAM and a faulty motherboard.

How? Say you have two RAM sticks and two DIMM slots. You obtained errors at the test with all RAM sticks installed. Now, remove all the sticks but one. Test it in all the available slots, one by one. Continue the same procedure for all the available sticks.
How to make the inference that is it a RAM issue or it is a motherboard issue? Suppose you have got the result like that:
testSlot1Slot2
RAM1ErrorError
RAM2GoodGood
It is a RAM, a bad RAM.

But if you have got a result like that:
testSlot1Slot2
RAM1ErrorGood
RAM2ErrorGood
It is a motherboard issue. The particular slot is bad.
Let us know the results.

Memtest Results

Hi Yoyo,

Find below the results of the test, i was able to do a full 7 passes but unfortunately on the first attempt, i forgot to take a picture so I re-ran the test up to 5 passes and all was fine. Also, please ignore the reflection of my table-lamp in the picture.

Attachment 330974

Yes, when i ran the SF diagnostic tool, it bluescreened a few times so i just uploaded what i could get hold of.

If you need any more information, please ask.

Thanks

Hi sorry for the late reply!

My gut tells me flaky hardware, but we can explore buggy drivers as well.
Let's start with Enabling Driver Verifier.

It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

warning   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 is no points, make a System Restore Point manually before enabling DV.

Tip   Tip

Please enable driver verifier following this TUTORIAL | But using the settings listed below:
Quote:

  1. Go to Start and type in "verifier" (without the quotes) and press Enter
  2. Select "Create custom settings (for code developers)" and click "Next"
  3. Select "Select individual settings from a full list" and click "Next"
  4. Select everything EXCEPT FOR "Low Resource Simulation", "Force Pending I/O Requests", "IRP Logging" and click "Next"
  5. Select "Select driver names from a list" and click "Next"
  6. Then select all drivers NOT provided by Microsoft, Unknown, or Macrovision and click "Next"
  7. Select "Finish" on the next page.
Let us know.

Hi Yoyo,

Very sorry I haven't checked this account in many months so I never got a chance to reply!

Unfortunately i'm still facing the problem so i will get onto enabling Driver Verifier and we'll see were it takes us!

Would it be a good idea to run a SFC /SCANNOW?

Would this sort out a buggy driver?

Thanks

Unfortunately I just ended up reinstalling Windows 7 onto the PC, must've been a few corrupt drivers in the old installation causing all the trouble!

Thanks for your help!
