Comp blown up

Got my new graphics card this week, unfortuntaly, two PSU blew up, seems the whole new comp is damaged. I removed the DVD, the soundcard and the memory from it, and those 3 compontens do work. I hope that the HDD and the CPU are good as well (will test them tomorrow, in case I feel a bit better, got a terrible cold :( ), but I fear both the mainboard and the card are damaged. Hopefully it won’t be a problem to get them replaced, as I believe that one of the two was really broken when I started the comp for the first time (didn’t get any video output). I presume it was the graphics card, which did damage the mainboard, now, it’ll be difficult to determine that. I’ll keep you informed.
