After buying new pc, it turned out it had shitty integrated card, so I got myself a new one which is
ATI Radeon HD 3870 X2
Yet, I can't seem to make it work. I plugged the card, plugged its cord into power supply, and launched. Fan is working (it's reaaally loud), and it also has red lights (good lights I guess). However, the card itself is damn dead. Plugging monitor into its extension results in black screen. Drivers for the card cannot find the card. Device manager or dxdiag also show zero signs of the card.
Current PC specs:
Intel Core i3 550
Mainboard - Foxconn H55MXV-LE
4GB RAM, and integrated card runs on 1gb memory.
Halp!
