Hi guys!

This is my first thread in Tom's Hardware, hope you guys can help me on this one.

I built a budget PC for my son a while ago and after a couple of years it was having some problems, so I decided to format the hard drive.. Everything was running perfectly after reinstalling the system and at a certain point Windows update asked me to restart the system. So I did, but it never came back on. I discovered it wouldn't turn on if the graphic card was attached to the mobo (A Nvidia GT640) so I used an old Nvidia GT430 I had.. It didn't work either... So I figured out it was a problem with the motherboard, so I bought a brand new H61 DGS, that has worked like a charm so far.. except by the fact it doesn't recognized the cards... I really can't believe that those 2 cards are damaged since they were working perfectly before it all happened so maybe it's a problem with the software... Any ideas?.

Thanks in advance, any help will be greatly apprecciated!
