Hello all,

The Problem

My computer started getting visual distortions on screen about a month ago. by this i mean horizontal bars of colour every couple inches all over the screen. I "fixed" this by getting rid of the dust and leaving the side panel off, as i thought the GPU was overheating.
Seemed to work for a while, however at the beginning of this week it started doing it again with the added bonus of an occasional Blue Screen stating memory parity errors.
The truely wierd thing is: it will run fine for hours if not days at a time but then the next time i use it theres a near instant fault. Played MW2 yesterday for about 5 hours and it was fine. 5 mins into a game today and i get the graphic errors followed by parity error.

The Computer

This beast is getting rather old, its a Dell Dimension DIM4700, but ive upgraded it a few times. It has 2GHz of ram, a Geforce 8800 GTS 512 GPU, a 2nd dvd player and a 530W PSU.

The Suspicion

Well the graphics card, memory and power supply are less than a year old so im hoping they arent the culprit here. Im not exactly tech savvy tho so feel free to tell me its one of those and make it a cheap fix for me . However i have a suspicion it might be the motherboard.

so anyone have a clue whats going on with this machine? is one part or every part faulty?
