Solved Random BSODs on new custom build with AMD A8 APU

dimah · Feb 9, 2012

Hi all, hope someone can help as this has me stumped.

I built a new PC with an AMD APU A8 Quad 3GHz using the onboard graphics in the APU with Windows 7 64bit. It was built about 1 month ago and the problem began as soon as windows was installed with no software other than drivers.

Since it was built its been intermittently bluescreening, mostly when playing games (installation of rift, during play of final fantasy XI , during starcraft 2) and also when browsing the web via firefox. Spotify is sometimes running and playing music in the background, although it has bluescreened without spotify even being open.

The error codes vary, mostly it is D1 with USBport.sys but has also come up with others as I'm sure you can see in the dump.

I tried a format and reinstall of windows, tried using only the latest drivers from gigabyte, tried replacing the RAM to a different brand and size (now it is using only a single stick of DDR3 2GB) It originally had 4GB (1 stick) or DDR3.
PC is running MS security essentials AV.

If you can help it would much appreciated, thanks!

Do the following steps and post back results of each.

Download and install HWiNFO64 for 64-bit Windows 7. Run with sensor-only not checked. Select save report, and save an .html file with your hardware information in a folder you will remember. Compress (zip) the .html file and upload to your next post so we can check for hardware incompatibilities. http://www.sevenforums.com/tutorials/9733-screenshots-files-upload-post-seven-forums.html
Run through the steps for http://www.sevenforums.com/tutorials/165554-usb-driver-general-fix-problems.html to determine any USB related problems.
Also, USB issues can be related to the BIOS version and chipset drivers, so make sure both are up to date for your system.
Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).
If you swap any memory components, follow these steps for ESD safety:
1. Shut down and turn off your computer.
2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working.
Once these steps have been followed, it is safe to remove and replace components within your computer.
Use HWINFO to monitor your temperatures. Start logging the temperature through sensor-only mode when the computer first starts, and let it run during stress or until a crash occurs.

Save the CSV file in a place you will remember, and then compress the CSV file to a zip file and upload to here for us to analyze by following the steps in http://www.sevenforums.com/tutorials/9733-screenshots-files-upload-post-seven-forums.html.
Use FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net to test the graphics card GPU. Then use the |MG| Video Memory Stress Test 1.7.116 Download to test your graphics card memory.
Run http://www.sevenforums.com/tutorials/100352-hardware-stress-test-prime95.html to determine any hardware problems. Run all three tests for a few hours each. If you get errors, stop the test and post back here.

Hi sorry haven't gotten round to leaving the memtest yet but will try that tonight or tomorrow, meanwhile here is the HWinfo64 html file. Its still BSODing randomly, last time was in the middle of installing a game.

Have updated the chipset and bios to the latest available on gigabyte's site, will check through the usb thread too and post back.

Thanks again.

dimah · Feb 12, 2012

OK -

I've deleted the greyed out USB entries in device manager and run Furmark and MG video stress test without any errors.

Will run memtest and then prime95 overnight but have not had any bsods since deleting the USB entries.

BSOD again while idle just now.

Posting HWinfo sensor log.

writhziden · Feb 12, 2012

HWINFO is giving erroneous temperature values below ambient (unless you have your computer in a 0 C environment). Try SpeedFan - Access temperature sensor in your computer

Got a new BSOD I haven't seen before while watching an .mkv in media player classic,. Was error bsod code 101.
Attached a new minidump...

writhziden · Feb 12, 2012

Memtest86+ and prime95 should definitely still be run. For further information on the latest crash: http://www.sevenforums.com/crash-lo...0x101-clock_watchdog_timeout-troubleshtg.html

dimah · Feb 12, 2012

Hey thanks for your replies,

OK Speedfan says CPU usage 0.2%
Fan1: 1024rpm
Temp1: 32C
Temp2: 86C
Temp3: 15C
HD: 43C
GPU: 11C

Can attach a print screen if you need to see.
*I Read the thread you linked to, what do you think is causing this?? I'll still run prime95 and memtest overnight.
I just can't believe it would be the RAM after I already replaced it, so its looking like the APU or the mobo in that case right?

Many thanks

writhziden · Feb 12, 2012

Most likely the APU given the 101 crash, but it could also be the motherboard or even the PSU. Prime95 would give a better idea. Also, speedfan is also reporting odd temps. Try Real Temp - CPU temperature monitoring and post a screenshot of the program's readout using http://www.sevenforums.com/tutorials/9733-screenshots-files-upload-post-seven-forums.html.

Download Real Temp 3.70 | techPowerUp

dimah · Feb 12, 2012

Just tried to run Real Temp but its giving me CPU not supported errors.

writhziden · Feb 12, 2012

See if you get temperatures with these:
Core Temp
Speccy - System Information - Free Download

Coretemp screenshot attached

dimah · Feb 13, 2012

Ran Prime96 all three tests passed with no errors.
Attached the results.txt if needed

writhziden · Feb 13, 2012

Alright, proceed with the Memtest86+ and Windows Memory Diagnostic.

dimah · Feb 13, 2012

Memtest v4.2 completed 12 passes today with 0 errors. Moving onto the Windows memory diagnostic next.
I've also got hold of another higher wattage (new) psu that I'm going to swap and watch some more videos tonight to see if its still crashing/bsod'ing during this.

Will post back if I still get bsods or if theres any errors on the mem diagnostic.

dimah · Feb 13, 2012

Completed the windows memory diagnostic with 5 passes, no errors.

I swapped the PSU earlier this evening for a brand new one, 500W... watched some more .mkvs and got a new BSOD after about 30-40mins into the vid. This time the error code was 0x0000000a ntoskrnl.exe

I suppose this narrows it down to the mobo since the APU wasn't giving any errors on the hardware tests I ran?

Going to try to get hold of a new one and will post back but it probably won't be for a few days. If you have any more tests or ideas for me to do please let me know.

writhziden · Feb 13, 2012

Did you run the tests on the graphics card? Results?

dimah · Feb 14, 2012

Yes, I ran every single test in your post and there were no errors on any of them. The computer didn't BSOD during any of the tests either.

What memory kit do you currently have in your system?
