Windows 7: Multiple BSOD 0x0a, 0x1a, 0x4e, 0x50, 0x3b (IRQL, SYS_SERV_EXC, etc)

Winsows 7 Professional 64 bit
Multiple BSOD 0x0a, 0x1a, 0x4e, 0x50, 0x3b (IRQL, SYS_SERV_EXC, etc)


I have a Dell Optiplex 9020 Lab with about 30 computers in there. The computers are running Windows 7 64 bit. There is one computer that has about 5 different types of bluescreens happening over the last few months. I attached a SF Diag Tool Zip. Any help on what could be the problem? I have run a system diagnostic test by Dell and it has passed perfectly.

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.

Memtest should be done overnight.

I ran the Memtest86+ and it found errors immediately, literally thousands of errors were shown. So to narrow down the issue, I removed one of the two 4GB ram sticks and just tested one single stick. The first one returned no errors after about 8 or 9 passes. Then I tested the second ram stick by itself and thousands of errors came up almost immediately. So I'm very positive it's a bad stick. Then I decided to use Windows Memory Diagnostic Tool and it found errors very quickly too.

Just to cover all options, I even ran Dell Diagnostic test tool and during the memory test a warning message popped up and said the warnings or errors were corrected. The test continued with no further warnings or faults. All these tests were being done with just the suspected stick that threw thousands of errors. Then I tried testing the single stick with MemTest86+ again, this time the testing didn't throw thousands of errors. Instead, has run smoothly without any errors, until pass 2 Test #9, there was one error. I still believe this stick is bad, but it does confuse me why the first couple tests with Memtest86+ would throw so many errors then on an additional test, only throw maybe 1 or 2.

skywalker89, There could be several explanations, but even 1 error is a fail. In the end it does not matter. Call technical support and request an RMA for both sticks and get a set in return. Sets are tested to run well together and individual sticks are not. So, you want a kit. Ask them about an advanced RMA. That way you get the new sticks before returning the old ones. You just have to give them a credit card number, in case you don't return the bad sticks. There will be no charges if you return them on time.
