I just got an Elite A780GM-A (V1.1) AM2+ ATX motherboard (holds up to 32gb DDR2) and a quad core AMD Phenom 2.5 ghz (the new revised one) and 4Patriot DDR2 1066 mhz 1gb memory sticks. I installed everything (including all 4 memory sticks) and fired it up and had no problems. I kept trying to install windows from a cd that turned out to be non-bootable. I got a bootable cd and installed windows and everything ended up fine. The problem is that the first time I was trying to install windows before I figured out that it was just the wrong disc, I removed 2 of the memory sticks to see if that would do anything. Obviously it made no difference but when I put them back in NOTHING AT ALL happened (not even a boot screen or bios) Since then it boots up and runs only with 2 1gb memory sticks instead of all 4 like it should. I know the slots aren't damaged because I switched them over and it works and I know the memory sticks are not damaged because I switched them out as well and it still works. It just won't work with all 4 now but before it did the very first time I booted it up. Anyone familiar with this problem?
