    So i ran the memtest and it gave me an inifite amount of errors all with different numbers but every single one included the same message

    "Mem Test has detected that your computer cannot accurately store data in RAM. You need to fix this"

    I would like to point out my laptop is only a year and a half old and that have never suffer any fall or hard hit etc
  3. This means you have bad ram.

    If you have multiple sticks of ram, remove all and run the test using 1 stick at a time.

    Sadly i only have one. What i did is i changed the ram to the second slot and ran the test again, errors were found but not as much as in the other slot, (1 every 30seconds insted of 100 per 30 seconds) does this means anything? or is just a bad ram plain and simple? do i need to buy another one?
  5. I need to add that the BAD_POOL_CALLER screen stopped and now i get a PFN_LIST something. dont knnow if that makes any difference

    You simply need to replace the ram stick it has gone bad.

    When you change the ram out with a new stick, re-run the memtests to ensure the new stick of ram is good as well :)
  7. As said, your stick of RAM has failed. Get a new one.
