Random BSOD on CS: Source

PolloSpeedo said:

Hello everybody!

Today, while playing Counter Strike: Source, a random BSOD appeared. I would like to clarify that this happened to a friend as I watched him play, so I hope it isn't a problem. Anyway, the matter is that he got a BSOD while playing the game online. Prior to that, the server got extremely laggy and some objects started clipping into each other, then the computer froze for about five seconds before the actual BSOD. What really disturbed me was the fact that the Blue Screen itself didn't contain any STOP errors nor .sys related messages. I've (sometimes) managed to deal with these atrocities myself in the past by googling those error messages and looking for a fix, but this one didn't seem to provide so much information. I hope you are able to enlighten me.
Blue Screens don't happen too often in his PC, but he has actually gotten before and this is the second one this month.

System Specifications:
- Windows 7 32-bit, Service Pack 1 (build 7601).
- Intel Core Q6600 CPU @ 2.40GHz
- 4.5GB of RAM Memory.
- Nvidia GeForce 9600GT 2GB

Thanks in advance.

Whatever machine this dmp came from is having memory issues. That combined with be up for 35 hours


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


1-Memtest.

*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.
