A few days ago my HD died. I had had a few problems the previous days and after testing it with some software, all of them agreed that I had to backup as the HD was doomed. Finally on Friday it gave up. I tried it with another mobo and nothing, so that was it.The funny part is that at about the same time my main mobo started acting funny. It wouldn't load the BIOS. I thought it was related to the HD, so I just left it there until I bought a new HD.Yesterday I got a 160Gb Sata Samsung and installed everything. Bios still wouldn't load and made long continuos beeps without end. Reading in different forums I found it could be the VC (which is 2 months old) or the RAM, or the mobo. I tried reseating everything, even changing the RAM from slots 1,2 to 3,4 with no results.So, when I was about to go out to get a new mobo, I made a final attempt. I removed one Ram stick and left the other, and this time the BIOS loaded. I tried doing the same with the other memory stick and again it loaded. Then I tried installing the sticks in 1 and 3 (2Gb no dual channel) and again it loaded. I finally went back to the 1,2 cfg, and I was back to the long beeps. I tried again 3,4 and same result.So the final result is that it seems the Mobo refuses to use dual channel cfg, and now the freq of the RAM is showed as 333 instead of the 400 the sticks are. I guess this is a BIOS problem (I reset the CMOS, but nothing changed).Any ideas?ThanksLeo

Mobo type? That might help... ;)
