Okay, so I will cry if I ruin my 2nd motherboard. I had to buy a new one for my Dell Dimension E521 because the last one died due to my dumb BIOS knowledge and processors. I just bought a new AMD Athlon 64 x2 Dual-Core 5000+ processor. (part #:ada3500iaa4cn) Now, I don't know if part numbers matter, but I put in the new processor and upgraded the BIOS only to find out that I just killed my mobo. So while the new one is on the way here, I want to find out what I need to do to make my new processor work with the motherboard. I have 3gb ram, a geforce 8600gt, and the motherboard model is a hk980 (or hk890 idk). But I really need help, soon before I ruin another mobo. (I checked with AMD by calling them to see if they had an update for my cpu and they said no.)
