One friend did tell me to try booting windows with PEG/PCI slot which would effectively disable the onboard card. Also, I cannot install drivers without new card plugged in, as it won't install until there's a recognizeable card. Unless I do it with monitor in onboard.
Also I think service guys...
Bought PC with integrated (or is it called onboard?) card. So, after few days, decided to buy myself a real card.
The new card: ATI Radeon HD 3870 X2
The PC:
Intel Core i3 550
Mainboard - Foxconn H55MXV-LE (and the pci x16 slot)
4GB RAM, and integrated card runs on 1gb memory.
500w PSU
First...
