Hello, I have a frequent problem with a motherboard. It is from an HP Pavillion Slimline s3400 PC. The model of the board is M2N61-AR. The problem started occuring a few months ago. At first, it would not boot up no matter what. Then, strangely, I found that if I unplugged the power cord from the back of the PSU, while holding the power button on the PC, it would start to boot. A few times, I was able to plug it back in when it would start to boot, and it would boot up fine, until I would turn it off, or when it would go into sleep mode. My first thought was the PSU. I opened up the PSU and noticed that some of the capacitors were blown. I then thought, "ok, it was just the PSU". Wrong. I had a few extra PSU's lying around, so I decided to use one of those. But, the board is micro-atx, so it has a micro power connector on it. I bought an adapter to go from a normal atx power connector to a micro atx power connector. It started up. It worked fine for about a week, but then it decided to start crashing. I thought that it might be windows. So I went to reinstall windows, but, when I booted the CD, it crashed a few seconds after the "loading windows files" screen loaded. I dont know what is causing this. Is the mobo bad? Or the cpu? The cpu is an AMD Athlon 62 X2 socket AM2 proccessor. Any ideas?
