Windows 7: Random BSOD Windows 7 64 Bits

Random BSOD Windows 7 64 Bits

I seem to get a BSOD at random times, only thing I noticed is that it happens at random times sometimes when playing Supreme Commander 2 or just surfing the web using Internet Explorer. Althought sometimes I can finish a game of Supreme Commander 2 without any issues, sometimes it crashes and when the computer restarts I get the below error:

Problem signature:
Problem Event Name: BlueScreen

It use to happen a lot with some games, but not with others. So I reinstall Windows 7 and its still happening. Its not just when playing games, sometimes it happens when I'm just surfing the web.

I noticed the below message with my dxdiag command, not sure if that could be the cause:

The file ctaud2k.sys is not digitally signed, which means that it has not been tested by Microsoft's Windows Hardware Quality Labs (WHQL). You may be able to get a WHQL logo'd driver from the hardware manufacturer.

I would appreciate any assistance regarding this issue. SF Diagnostic Tool details file for my pc is attached.

Take memtest. Run for 8 passes and test each stick in a know good slot for an additional 6 passes.
The goal is to test all the RAM sticks and all the motherboard slots.

Check your motherboard manual to ensure the RAM sticks are in the recommended motherboard slots. Some motherboards have very specific slots required for the number of RAM sticks installed.

If you get errors, stop the test and continue with the next step.

1. Remove all but one stick of RAM from your computer (this will be RAM stick #1), and run Memtest86 again, for 7 passes.
*Be sure to note the RAM stick, use a piece of tape with a number, and note the motherboard slot.
If this stick passes the test then go to step #3.

2. If RAM stick #1 has errors, repeat the test with RAM stick #2 in the same motherboard slot.
*If RAM stick #2 passes, this indicates that RAM stick #1 may be bad. If you want to be absolutely sure, re-test RAM stick #1 in another known good slot.
*If RAM stick #2 has errors, this indicates another possible bad RAM stick, a possible motherboard slot failure or inadequate settings.
3. Test the next stick of RAM (stick #2) in the next motherboard slot.
*If this RAM stick has errors repeat step #2 using a known good stick if possible, or another stick.
*If this RAM stick has no errors and both sticks failed in slot#1, test RAM stick #1 in this slot.
4. If you find a stick that passes the test, test it in all the other motherboard slots.

If Part 2 testing shows errors, and all tests in Part 3 show errors, you will need to test the RAM sticks in another computer and/or test other RAM in your computer to identify the problem.

In this way, you can identify whether it is a bad stick of RAM, a bad motherboard, or incompatibility between the sticks.

Errors are sometimes found after 8 passes.

Do this test overnight, before going to bed.

I ran the memtest86 test, and I got some results in Red, which I guess means I had some errors come up during the test. But I'm not sure as to how to make sense of the test results. But I also noticed that I had a MemOk button on my motherboard, and I follow the instructions to setup the ram using that button, and I got the the results I have attached as a screenshot.

This seems to have put a stop to the issues while running applications(no more game crashes), but I still get random IE errors, not sure if thats related to specific websites having issues with the IE web browser.

Even after runing the MemOK setup, I still got errors after runing the memtest86 test. But since I'm not sure as to how to interpret the results, I'm not 100% sure.

Thanks for the help, so far. I also have attached a screenshot of my memtest86 results.

1. You look to be overclocked. Don't. Enter bios and set optimized defaults.
2. In the overclocking section of bios, set your memory to the manufacturers specs, especially the 1st 4 timings, and voltage. Set them by hand. The settings will be on the package your ram came in or on a sticker on the ram sticks themselves. It will read something like 9-9-9-24 1.5V 1333. These will be set in the overclocking/ tweaking section of bios. The voltage will be listed as dram voltage.
3 download and install CPUz. Run the program and post a screenshot of your memory and SPD tab as well as the mainboard tab. Use the snipping tool. ( click start, in the search box type snip) You can set it to window, which takes a snip of the entire window you click on or rectangular to draw a rectangle around the area you want it to save. Name them and save them on your desktop. upload them in your next post.

You need to read koolkat's instructions for running memtest and follow them. You can stop any test as soon as you see an error. I know it is a long tedious test, but we have all been through it, numerous times. It is critical to have your ram error free to stop BSODs.

Thanks for your help koolkat77 and essenbe. I ran the memtest86, seems like one of my 4 sticks of Corsair RAM Memory was bad, I followed the steps removing and replacing each stick of RAM looking for errors and only 1 stick came up with errors. After removing it, and running the memtest86 test, I saw no more errors, and I'm no longer getting errors when running games, or the IE browser.

One final question, another one of the issues that I was having that I did not mention was getting errors when installing games, and this is not happening any more after removing the bad stick of memory. I can see how bad RAM memory can create issues when using applications, IE, games, etc. But how does bad RAM end up creating errors where you get messages stating that the source from which you are installing might be corrupt? It had to have been the bad stick of RAM, since I tried the same two DVD's after removing the bad stick of RAM, and I'm no longer getting those errors.

Thanks for the help again.

I can't say that bad ram caused that, but I can say that a stick of bad ram can cause a multitude of errors. Most of which, the error codes do not directly point to ram. When the ram hits the 'bad spot', it just depends on what you are doing at that moment.

Are you sure you have the ram set correctly in bios? You never showed the screenshots of CPUz. Did you run memtest for 8 passes? Until you do, you will not know for sure if you have other ram problems. What frequency, voltage and timings are on your ram sticks?
