Several BSOD while using Windows 7 64-bit


During the last week I have had several bsod's while using windows 7.

I searched the forums I already updated all the drivers, applied windows updates, uninstall security protection, tried the sfc / scannow command, the chkdsr /r but no luck.
Every now and then I get a BSOD.

I tried everything and still can't fix this problem.

The bugchecks are:
NTFS_FILE_SYSTEM (0x00000024)

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.
information   Information
Errors are sometimes found after 8 passes.

Tip   Tip
Memtest should be done overnight.

Attached is the screenshot of the speccy. Every temperature was green.

As for the memtest, I only had time to do the test with both sticks on and it stated several errors after 2 passes:

Total: 47116 errors
Error confidence value: 177
Lowest error address: 0002fe68000 - 766.4 MB
Highest error address: 0007fefefffc - 2046.9 MB
Bits in error mask: ff00ffff
Bits in error Total: 24 Min: 1 Max: 19 Avg: 4
Max contiguous errors: 256

Test 5: 3552 errors
Test 8: 43564 errors

I will test the individual sticks now.

Hello brunoredline, did you download the test from Memtest86+ - Advanced Memory Diagnostic Tool? As Koolkat has explained, you are trying to determine if you have bad Ram sticks or bad Dimm Slots. Keep track and run each stick, one at a time, in each Dimm Slot. That way we can determine which is the problem. If you have any problems, please let us know and one of us will help you.

Hi essenbe.

No, I downloaded from MemTest86 - Offical Site of the x86 Memory Testing Tool.

Which one should I use?

Memtest86+ is the best one. Please don't ask why they have names so much alike. I would not run the same test you ran over again, but I would use memtest86+ for the tests you have yet to run.
