Hey guys, I reformated my Windows XP with a clean install of Windows 7 Home yesterday. All was working well; Today I went out and bought two 1GB pieces of ram, installed them, and used my computer. Everything was working perfectly. I went out, left my computer on (turned my monitor off). Came home later, turned my monitor off, and got a messaging about "Power Save Mode". The monitor light then went from green to orange. I tried using a different monitor; same thing. On the front of my Dell are the 4 diagnostic lights. When I turn the PC on, number 1 is green, but the rest are off. According to Dell, this means there is a problem with memory (RAM?). Also, note that when I press the power button to turn my computer on, and makes a 1-3-2 beep pattern. Anybody have some suggestions? Thanks BH'ers EDIT: Exact same problem even when I take out the new RAM, and only leave the old RAM in.
