All games crashing on new PC

[marko.dimitrijevic.ns]

Hello, 2 months ago i have bought 2 new prebuilt PC's and one of them is working great while other one have some problem, there is same windows and drivers at both of them, everything is up to date.

At that one PC every game that i run crashes to desktop it's not too often some times it happens after few minutes in game and some times game runs fine for a few hours so it happens at random.

The other thing that i have notice, google chrome browser often just stop responding and show "Aw snap" error but don't close to desktop as games do and after i reload the page all runs fine for some time again.

There is not any specific error that windows show up, in windows Reliability Monitor some error's shows up in time of game crashes and description for all of them is this: Faulting Application Path.

I took the PC back at the shop and they did run some testing and told that everything is fine with pc, the only thing they found out is that CPU temperature is a higher than normal so we bought a better CPU cooler and 3 more additional for the PC case, guys at shop placed it all inside, tested it again and told me that everything should be fine now.

But the same problem is still here, crashes still happens even with new coolers (the other PC working just fine with first CPU cooler they came with) so i'm pretty sure the temperature is not the problem.

After some research i begin to suspect there may be a problem with RAM, a faulty RAM or something, so last night i have run a memtest86 and it did find one error.

Here is the report from memtest86:

I'm not sure what that one error means, or is it enough to say that the ram is causing problems, im planing to run the test again soon to see will it find something again

I have realy no idea what should i do, so if anyone can have look at it would be a great help.
Thank you and if you need some more information please be free to ask.

I did try windows reinstal and different video drivers with no luck.

What happens if you swap ram between pc's? And i mean complete sets.

Well that's another problem, i can't open the PC case or i will lose warranty (there are some stickers at the back which will tear if i open it), i could take it to the shop again and ask them to do it and to place the sticker back, the thing is if i bring it to them they will keep PC for a week or two probably, so i would just like to be sure before that since last time they didn't really help.

Since prebuild should they just fix it anyway. Don't know what test they did,but if not giving the same problems should they extend their testing or at least just swap the ram since memtest seems to give errors.
