Issues with WoW

[vandris]

Greetings,

Yesterday I bought a new computer with the following specs:

MOBO: ASUS B85M-G, PCI Express 3.0, USB 3.0, SATA-3/6G
CPU: Intel Core i5-4570S
RAM: Kingston 8 GB 1600 MHz
GPU: GTX 750 Ti 2 Gb DDR5
PSU: Cooler Master 500W
HDD: WD 1TB 32MB 7200rpm

Op. sys.: Win 7 Ultimate 64 bit

I have installed all the latest drivers etc. and I decided to try out WoW without addons. After a few minutes the game froze completely, I was unable to alt-tab and had to reset the machine. On the second try the same happened, I was just flying around etc. when suddenly the minimap started to fade and when I tried to open the world map the game froze again just like on my first attempt.
After the second attempt I completely reinstalled the Windows and WoW too. This time I was able to play 25 minutes before the game decided to froze again, but I could alt-tab, after a few seconds I managed to get back to WoW to see that I've been disconnected.
I haven't tried to play since then.

Please help, I'm just so puzzled right now that my brand new machine does this.

Thanks in advance for your help!

Hard to say, did you build the computer yourself ? If not just go back to the store.

No, it was built in the shop since I'm unable to do it.
