Recently brought my old gaming PC out of my storage unit, only to have it post one long beep, and three short beeps. Found out it's a Conventional/Extended memory failure. Tried re-positioning ram, switching ram spots, but still the same post. Eventually I got some other ram, that I know for sure works, and installed them only to get the same post. Why is this happening? It's an Asus P5QC mobo, and I'm using an Intel Pentium D 945 as the CPU. I haven't had this problem before with it, and It has only been in my storage unit for a couple months. All help is appreciated.
