My computer wont game :(

Hello,
I just bought a new computer for work and made sure it was good enough to handle SW:TOR
its a 2nd gen i3 3.3 clock with 6 gb of ram.
I added a GT 520 2 gb graphics card to it so it'd game.
I know its not a great card but its what I could afford after everything else I bought.

The issue is on launching SWTOR it will freeze permanently after 2 minutes of play. even 2 mins at toon select.
I tried beta drivers and regular drivers and everything else I was told to look at and no joy.

I tried WoW on it and it crashed that the same way.

Anyone got some advice?

need more info... full system spec's

Probly bad card sounds like to me

its not heat, my machine is running cool.
I've tried out various drivers and they all fail.
the game runs on the i3's in build graphics albeit not amazingly so the card should be able to run it without freezing the machine.\
I can barely play - it will let me in for a minute or two then freeze or die.

Power Description

Maximum Power Supply Wattage 300 W

the power supply is lower than i'd like but I was assured I had enough to run the card.

I'm thinking bad card too. I'm probably going to take it back for a refund. So given the above specs and about $100 what should I replace it with?

cool, I found a replacement power suply for my make tower for $40 thats a 575w so I may just get that 1st then pick up that card. thanks for the replys

I took to card back as it seemed to not be working properly. the geek at best buy agreed that the card seemed faulty.
After putting in the updated power supply I have not got a new card.
However the i3's inbuilt graphics is running SWTOR fine.

It seems to be honest that the computer gets starved so I'd recommend upgrading the supply before you do anything as my machine runs so much better now.

thats where I got the unit from. It was my 1st psu swap and it was nice and easy.
I recommend getting from them.

switch that up and your whole computer will thank you
