BSOD Memory Exception Error

Hi

1st post, this is a problem that is driving me nuts.

I get Memory Exception blue screen cashes and other assorted error messages regularly, i.e every session. Stating there is a 'memory exception' or similar.

I have a faint blurry band across VDU from time to time but not constant, which has led me to believe this problem could be graphics card driver related but having installed latest this doesn't appear to be the culprit.

Seems to occur when computer is playing music/video or has a sudden demand to do something graphically i.e when chrome has many tabs open and I flick. It should be noted that I have a hdmi from my graphics to my TV set up, not sure if this is causing something to crash?

I was wondering whether my CiT 650 watt PSU was to blame, considering replacing this for a Corsair 750.

Besides the crashes, performance is sluggish for the spec.

Any advice much appreciated.
