Do you know what the error codes on the blue screens were?
This can help identify the source of the problem.http://www.memtest.o...6 -2.11.iso.zip
Download the file above and unzip it. You should get a file that has the extension .isohttp://www.snapfiles...t/burncdcc.html
Download this, and load up the iso file you got earlier. Burn it to a disc using this program at a slow speed (1X)
Once you have the CD, you should take out all sticks of RAM from your computer except one.
Boot from the disc, and run the memory test for at least 7 passes.
After this test passed or failed, try the other stick of RAM (if there is another).
You might want to run the test overnight.
Reply with the results.
