Windows 7: BSOD on start up

BSOD on start up

For several months I have been getting the BSOD at start up. Usually I could just restart and everything would be fine. Last night I couldn't get it to go after three tries. Any help would be wonderful. I hope I did everything right.


And both types refer to file ntoskrnl.exe

Welcome to SevenForums

If you are overclocking any hardware, STOP. Reset any changed values back to default.

Perform a clean boot:Make scans with the following:

-Kaspersky TDSSKiller-ESET online scannerPerform a System File Check:
  1. Click on the start
  2. Type CMD on Search
  3. Left click and Run as Administrator
  4. Type SFC /scannow
Full tutorial here:Upload a screenshot of your hard disk using CrystalDiskInfo:Run Disk Check on your hard disk for file system errors and bad sectors on it:Hard drive test both short and long with: Also the DOS version of:For monitoring the heat/celsius of the system, use Speccy or HWMonitor: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
Do this test overnight, before going to bed.

If Memtest86+ does not find any errors with ram run Windows Memory Diagnostics for 7-8 passes following its tutorial:Let us know the results.
