When/where does it freeze?

When/where does it freeze?

it freezes even on desktop at idle .. i tried another gpu because i taught that could also be the cause and it still froze..
and btw i stated that i already tested the ram and cpu. i used memtest 86 and prime95 and they ran for about 10 minutes non stop and the temps were fine and it did not crash or anything.. i even tried lower the ram speed to see if thats the issue and still no good... i took out all the ram sticks except 1 about 1 hour ago and left the computer running and it has not frozen up so im kinda thinking that might be the issue but i cant tell for sure yet.. what you guys think ?

Memtest takes HOURS. 10 mins does absolutely nothing. Run it overnight and see if you get errors.

ok i set it too run and it took over two hours to finish and it ended with no error whatsoever .. however at the end where it say press esc to exit the keyboard goes dead and wont respond and i have to reset the pc with physical button.... its really frustrating me now because i need it for work purposes .. all the parts are brand new and are placed in the system properly yet its giving me this much pain ... sighs ..

You said it does not happen with only one stick of RAM installed?

yes that what i noticed earlier... i went back in the system and switch around the ram modules earlier and was gaming on it for hours without any freezing but i doubt that it is fixed because it only happens randomly .. the pc is ony like 3 weeks old and at its first boot up it was ok but as soon as i installed the gpu drivers it would not pass the windows 10 logo .. so i reformatted the pc and installed a different card and it passed the logo however now it starts freezing like randomly .. as i stated before everything is brand new .. BTW i forgot to mention other than freezing randomly the computer will freeze as soon as i open Revit Architecture or Auto Cad .. as soon as i open a project the pc freezes guaranteed every single time .. do you guys think i should return all the parts just to be safe and get them all replaced or give it some time to narrow down my results

This sounds like bad RAM to me. I would return the RAM and get a new set.

turns out the it was bad ram and bad power supply ... tested them separately and used them individually in other system and they both crashed so i replaced them both and now my system is properly functioning.. i mean what are the odds of both being delivered defective .. oh well thanks anyways guys
