Windows 7: BDOD Playing Combat Arms

05 Oct 2011   #1

Windows 7 Home Premium: 32 bit
BDOD Playing Combat Arms


I purchased a computer several months ago and since that time I've been getting BSODs a lot, especially when playing Combat Arms online. There have been few other instances but not with any regularity. Combat Arms accounts for 95% of the BSODs.

I did a lot of reserch online to trouble shoot the problem including: clean install of window 7, purchase new (larger) power supply, different monitor, different RAM, different mouse and Keyboard, went from 64 bit to 32 bit install of Windows, 3 different graphics cards, install manufacturers drivers, Cleaned and reseated the CPU fan, and disabled the extra media slots (card readers). None of this has worked.

However, I did go into the device manager and boticed and unknown device: the 'coprocessor.' I attempted to find drivers but the device is unknown, I also looked online but didn't find much. So I disabled it. Cince that time the BSODs have occured much requently, but still occur and it's beggining to get on my nerves.

I did find soemthing relating to the chipset driver for the motherboard. But the manifacurer only offers drivers for Windows Vista. I tried those just to see, and it didn't help. This forum is my last hope.

My system is: Gateway GT5685E

I've included the html page of the system specs. The diffeences are:
NVIDIA Geforce 9600 GSO graphics Card
Window 7 Home Premium (purchased)
Seagate Barracuda 7200 750GB SATA Hard drive
WD Passport 500GB USB
Large CPU fan with an intake tube
Internal Fan
Mouse, keyboard, monitor

Any help would be really awesome.

Win 7 64bit Ultimate

exception code: "0xC0000005: STATUS_ACCESS_VIOLATION indicates that a memory access violation occurred."

The debugger is pointing to afd.sys which is a windows system file

Usually when it points to a windows system file it is a bit more complicated.

IS your copy of windows fully updated?

Run memtest86+ by following these instructions.
RAM - Test with Memtest86+

It will take atleast a few hours, so be patient.

Post back with results

Good Luck

Win 7 Ultimate 64-bit. SP1.

Hello jwhayes76.

These were caused by a memory exception. Please run these two tests to verify your memory and find which driver is causing the problem.


*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program.
Memtest86+ - Advanced Memory Diagnostic Tool

*Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

2-Driver verifier

I'd suggest that you first backup your data and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Win7 Startup Repair feature).

In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

Then, here's the procedure:

- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

If you can't get into Windows because it crashes too soon, try it in Safe Mode.

If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.
