Before you proceed with the following, answer these two questions: Are you still under warranty? Does your warranty allow you to open up the machine to check hardware?
If you are unsure of the answers to these questions, contact your system manufacturer. WARNING: The steps that follow can void your warranty!!!
Have you tested the RAM individually through doing your normal routine in Windows?
Since your blue screen crashes occur regularly, we can test the memory through running Windows. Test the memory slots as follows.
- Shut down and turn off your computer.
- Unplug all power sources to the tower (unplug the power from the outlet/surge protector or PSU).
- Hold down the power button for 30 seconds (for your safety and the safety of the components) to close the circuit and drain all power from components.
- Remove the casing.
- Remove all but one memory module making sure you are grounded while doing so.
- Replace the casing and put the remaining memory modules in a safe, static free environment.
- If the problem persists, repeat steps 1-4 and move the memory module to another slot (while staying grounded, of course).
Do this until all slots have been tested. If all slots fail, the memory module may be bad. Test with one of the remaining modules. Continue one module at a time in one slot at a time until you find a good module and good slot. Test remaining modules in the good slot, test good modules in other slots to find bad slots, etc.
Test by doing your normal routine in Windows for twice as long as it takes to get a crash or until you get a crash, whichever comes first. You can also test by doing the tasks that generally cause crashes.
