So I got my new rig...G750JS-T4193H

Hooked up a HDMI monitor + Bluetooth sound (I agree, the built in speakers ... could have been better)..

Start playing BF4 on high...

10 minutes in...I get "Computer is running low on virtual memory"

Thinking..WTF...checking RAM..good, increasing page file....good...going back to play...

Playing...15-20 minutes...the game stops, rig goes to SLEEP! WTF???? Bringing it back, start again....15-20 minutes - BOOM, out and
asleep...worried..

Keep playing after restart...get low on memory message..then DIRECTX error (x2)!!!!! E_OUTOFMEMORY and ERROR_NOT_FOUND

Very worried indeed, need some assurances that my AU$2.300 is well spent

Admittedly, haven't tried other games, haven't tried playing on its own screen, haven't checked the Intel graphics driver (NVidia is up to date)...

Help?

Thanks guys.
