Posible Ram error

[Ace13]

Hey, I've got a problem with my PC, and I think my memories give the errors.Sometimes I get artefacts and after few seconds the screen goes black or blue screen and the only option is to restart the PC. And even when I restart the PC, the artefacts continue to appear. When I run memtest I get all sorts of artefacts while.
Hope you will give me some opinions. Thanks in advance.

Sounds like a gpu error to me.
Update your graphics drivers.
For ram download Memtest86+ 4.10
burn iso image
boot from disc
test one stick at a time.

I tried memtest86, got weird artefacts and then a blue screen and now my PC still gives artefacts but wont get passed the windows boot screen.I have Ati 3870x2 and the most recent driver.

I would add/remove dump all ati
Download Driversweeper
run in safemode
check off ATI
Click analyse
click clean
reboot normal
install last stable version of CCC as Admin

I cant do anything because my pc wont pass through *Loading windows* screen cuz of the artefacts wich freezes the pc and gives me BSOD.

Before all this I tested my video card with Fur Mark and didnt gave me any error or artifact, and when I tested my memory with memtest86, the screen started to spam with artifacts...my question is... can RAM memory cause artifacts?
