I've tried to do that but to no avail. I downloaded memtest86 (regular memtest86 not memtest86+) from other site, which is also official memtest site and it worked. Did 10 passes last night on one of the RAM sticks and it went without errors. What is the difference between memtest86 and memtest86+ ? Is it just the number of passes ?
Tonight I'll do 10 tests on other RAM stick and keep you posted but i really doubt RAM is causing all this. Could problem be related to GPU memory or SSD, HDD ? Also could faulty keyboard cause this, because i spilled some water on this one while using my old PC and it is working but not all keys.
