Hi, This is my kids computer, I was replacing the Graphics card from my computer to theirs, both computers were working perfectly. When the graphics card was replaced into the kids computer from mine, the kids computer would not work and the monitor just goes into standby. I have tried to put the old graphics card back into it but I still get the same. I have tried taking the ram out one by one nothing chnages, it does give a great big beeep when I take one of the rams out. I took the power cords out of all the extras, hard drive dvd etc and continued to put them back one by one nothing changed. I even went and bought a bigger psu and replaced that still nothing. I've reset the Cmos and took the battery out but nothing. Everything seems to be ok on the motherboard no leaks or bulges but I am suspecting the motherboard or the CPU could be the problem, how or why I have no idea when it was working. I'm not sure whether to replace the motherboard or not or how much that would cost? Neither do I know what motherboard it is, I am just wondering if anyone has any ideas or if anyone can tell me how to identify the motherboard to see if I can replace it when the computer does not turn on? Thanks
