This is a picture

Look again at the board and check the model number. The specs say a 4 pin ATX 12V connector. But your pictures clearly show an 8 Pin plug.

As far as the PCIe card, you can see if you can return it for now, or try to sell it. But, yes, I've built more computers than I care to count. But, it's been a while since I built one of the model you have.

Why don`t you just drop it off at a shop, let them look it over, then have them give you a price to get it up and running.

Before you destroy it

You're right. Darn links, it said DS3P but went somewhere else and I didn't look.

Do you have any friends who are good at computers and maybe have some spare parts they would loan you to try out. The spare parts would help you more than anything else. We could swap parts out one at a time until we figured it out. We will stay with you and help as long as we have some ideas and things to try. When you bought it did they tell you what was wrong with it, or give you any idea?
