Installed Motherboard. Power will not stay on now. Fans start to spin, the computer shuts off then tries to start again & again but will not stay on. Changed power cord, that's not the problem. Tried the old ram, then tried the new ram, no difference. Fans will only spin for a second or two.
Searching the mobo for numbers was a daunting task due to how small the numbers are and whether you have a zero or the letter O. Looking at the motherboard that I ordered, (Acer M3970 Intel Desktop Motherboard S1155 MB.SG50P.007) said that it was for the Gateway DX4860-UR28. The 22 letters and numbers after the S/N on the mobo had no dots but the first 10 matched the MBSG50P007 so I looked on my original mobo and saw that the first 10 numbers were different, (MBSHA0P002). I then ordered the correct mobo and now the computer works fine. I also now have extra ram and a video card if I want to upgrade the machine, an expensive troubleshooting method. Using the Crucial scanner, instead of saying that it is a Gateway DX4860-UR28, it now says it is an Acer Aspire M3970
