It can be a pain but if you don't test it systematically you may never find the problem. If none of them fail by themselves in any slot, start combinations with two sticks. Be y each stick in every slot if necessary. If that's the case, then repeat with the next stick. Continue until you find the culprit, or until you prove that stick good in every slot. What happens? If it passes, move it to the next slot and run it again. Make sure your voltage and timing settings are stock as well. Anyway, if it's failing memtest at stock settings, you've got bad ram or a bad board. Memtest keeps running even if it detects errors.unless your ram is so screwed that it can't even make it to memtest. So you tried putting everything back to stock settings and running memtest, and it failed? I'm not sure what you mean by 'it didn't pass memtest and then it tried to boot'. This is after i set it to boot from the Hard Disk 'Disk Boot Failure, Insert System Disk and Press Enter' so anyway i went into the Bios and reset everything to factory settings and tried to boot, didn't pass memtest and then it tried to boot and got the error message So i downloaded FurMark and ran the default stability test and it got about 30 seconds in and then screen had some weird colors everywhere and it completely froze, couldn't even hit the reset switch had to turn off the power.
