System will randomly reboot and throw 0x000000c2 BAD_POOL_CALLER

Hey everyone, I got a system i;m working on that is used primarily for CAD and billing. When I encountered it, it was crashing due to having wrong video drivers and wrong sound drivers and the user likes to stream music and was complaining of stuttering then crashing. They also stated it would randomly just reboot when left alone. They are using quick books and after a reboot it seems that the event logs shows that as throwing many errors and we think it may be the culprit at this point but would love some insight from anyone.

All the dumps are included that they had on file, although the all bu most current seem to stem from the video and sound issue prior to this one now. They had an issue with DPC latency before that I fixed and now the only problem is the random reboots.

If you need more info on any part of the system please let me know.

Thanks
Malcolm

The problems with the video card are all 0x116 (VIDEO_TDR_ERROR) which is a Timeout Detection Recovery, these could be down to drivers, power to the card, the PCI slot on the motherboard, overheating etc. Basically you'll need to monitor temperatures and check for overheating, check the rating of the PSU, try uninstalling the card and reseating it (checking all power connections) then clean installing the drivers, trying a different PCI slot, running all of the things you'd need to do to troubleshoot a graphics card issue.

Run Furmark to stress test your GPU. Video Card - Stress Test with Furmark

   Note

Run Furmark for around 30 minutes.

   Warning

Your GPU temperatures will rise quickly while Furmark is running. Keep a keen eye on them, if the temperature continues to rise steadily once it has reached 80°C be prepared to stop the test so as to not damage your GPU.

The other dump is a 0xC2.

Code:

BugCheck C2, {7, 109b, c011e810, fffff900c06d0d70}

GetPointerFromAddress: unable to read from fffff80002eb2100
GetUlongFromAddress: unable to read from fffff80002eb21c0
Probably caused by : win32k.sys ( win32k!FHOBJ::vFree+51 )

To be on the safe side test the RAM.

Download and run MemTest86+ to test your RAM. RAM - Test with Memtest86+

   Note

Run MemTest86+ for at least 8 passes. Ideally set it off before you go to bed and leave it overnight, we're looking for zero errors here. A single error will show something's going bad with your RAM.

If the RAM passes then it's probably a driver that's causing the issue so I'd normally recommend running Driver Verifier, but the chances are it's the GPU driver. Run the tests on the GPU and the RAM test and report back, we'll take it from there.

Thanks will give all of those a shot when I get the chance and report back. The psu is a 500w antec I can get the model later if you want. its 12v + rails was 22A though So I figured it was good enough and it is rebooting not at load. Will definitely check the ram.

Thanks again
Malcolm

Did you assure it's Enable hardware auto-updating via Windows Update (Step 3)
then install all Important and Optional Windows Updates which may include patches to make the hardware work correctly. What driver does Win7 want for GPU?

We have installed the latest AMD driver for the r9 2xx series.

No not yet and I have gotten from the unit better specs for you all now though.

Supermicro 5038D-I
E3-1225v3
Kingston ECC KVR16E11/8M
ASUS R9290-DC20C-4GD5
Antec Basiv BP550 550W 80plus Adv

Thanks for all the suggestions so far I will try them all.

My two cents worth try this

UsingHW Info

PART A:

You can test the volts on the PSU with HW Info HWiNFO, HWiNFO32/64 -Download < download the right bit version andclose the right hand window select Sensors and scroll down to the power sectionwhere you will see what the volts are doing see my pic. In my pic the section (Nuvoton) with VBATT is a dead give awayyou are in the section for the rail voltages. There are other section titlesand one that pops up often is ITE

Now the voltage on the different rails have to be within 5% =+/-of what is required or the machine will not work properly if at all.

See this for the rail voltage info

http://www.tomshardware.com/reviews/power-supply-specifications-atx-reference,3061.html (Section 2.)

The original right hand window shows the machine running and ishandy for that but for looking at the components in some detail close it anduse the main left hand side panel

FOR OTHERCOMPONENTS

PART B:

Open each small square with + in it on the section thecomponents are in and then click on the individual component/s (it will highlight in blue) - in the righthand side will appear all sorts of details including brands speeds and otheressential info that particular device. See pic for example.

Use PART A:

If you need to recalculate the power needs this is useful too
eXtreme Power Supply Calculator - The only power supply calculator trusted by PSU manufacturers and computer enthusiasts it will give you a readout with a measure of error (upwards)

So we loaded up furmark and the gpu hit 97c but never artifacted or crashed and the app he uses for work only raised the gpu to 54c and only uses 450MB of vram so its not being stressed at all and it never crashed during any of this so now we wait and see if it happens again and throws same log. Will try the hwinfo for volts next thanks for the info John.

Thanks everyone for the continued suggestions, I haven't had time to try them all yet but will report back my findings when I do.
