Hello,
I have recently build a new pc. After doing a clean install and installing all the the drivers, everything seems to run fairly well, however when I try to run anything that requires a lot of energy the computer will freeze. The core temperature was at 31C when it froze and i had just installed a new heatsink too.
Here are the specs:

Motherboard: MSI 970A-G46
CPU: AMD fx 8320
Graphics card: I dont really know, it was an older one given to me by a friend that i used in my last computer, Canyourunit says I have an ATI radeon HD 2600 XT
Power Supply: box says WT480q, says it is 480 watt
Case: Raidmax horus
Even running runescape on lowest settings will freeze it after a couple of minutes, any help would be appreciated.
 
damn, i was afraid of that. So i was going to add a Geforce GTX 660ti card to replace the old one, will the power supply that rolli59 mentioned (http://www.amazon.com/dp/B00DGHKK7M/ref=asc_df_B00DGHKK7M3370701?smid=ATVPDKIKX0DER&tag=pg-401-34-20&linkCode=df0&creative=395097&creativeASIN=B00DGHKK7M) cover it? i dont plan on overclocking or anything fancy.
