Dell Dimensions B110 will not turn on.
I have a Dell Dimensions B110 and my issue is it will not turn on. this first happend when i accidently switched a "Value RAM" from the one that came with the computer. I have tried switching it back but it did nothing. i hesar the 1-3-2 beep sequence so i know it is a memory problem; the diagnostic lights are green-yellow-yellow-yellow. the power button remains green and there is no flashing. any help willl be greatly appreciated. i have been trying to fix this for several days.
