A friend built a computer for me a year ago that's been working fine up until now. I had it off for a few days while I was away, and I came back, turned it on, and now it just beeps at me and does nothing. The monitor remains on stand-by while the computer beeps.
Unfortunately I know little about computer hardware, and the friend who built it for me lives several hours away, so I'm hoping people here can offer some insight. The motherboard is an MSI K7N2 Delta, and the D-Bracket 2 was installed so I get the diagnostic LEDs on the back. The pattern of red-green lights shows that the problem is with the "Memory Detection Test." I looked on the MSI site, and the beeping pattern fit in the "RAM problem" category. So it seems that is indeed the problem area.
I tried switching the sticks around (I have two 512MB sticks, one in DDR1 and the other in DDR3) in various patterns and no luck. Tried one at a time, tried them in different slots, nothing.
