Hi MrBabis

It sounds as if your PSU failed and fried your motherboard. It might also have killed the RAM and AGP/PCI cards.

Like TheDuck I have not seen a "dead" card or memory damage a PC................it just doesn't recognise it.

I would recommend using Windows, as you will have a better chance of getting drivers for your cards. You need to be able to test the card, not just have it recognised by the BIOS............after all I have seen many cards that were recognised but were partially damaged, and would not work properly
