2009 Mac Mini Problems

[nross33]

Hello, I have the basic $600 Mac Mini from late 2009 with the 2.26 GHz intel core 2 duo processor, 2GB of RAM and a 160 GB Hard Drive, I wanted to put in 8 GB of RAM so I order it from OWC and install it, boot it no problem it works great. Now days later I was moving my mini to a different area of my desk and both areas are cool and allow it to ventilate and I did not drop or bump it and when I plugged it in the fan would just kick in on full and it would not power up, as soon as I unplugged it and plugged it back in it did the same thing, the power button would not do anything and it did this on its own as soon as I plugged it in not when I hit the power button. So I just opened the case attempting to boot it open and It powered on so I closed it and it was fine. But now every time I boot it up or restart or basically every time I get the loggin screen it will first go blue, then sometimes kind of flash and then take me to loggin, it never did this before. Another issue is when I tell it to go to sleep now it will not, the monitors will go to sleep but the power light now stays lit and the fan stays on. I tried taking out one of the 4 GB Modules of RAM to see if that was the problem and no still happened, I checked all the connections, they all appear to be fine. Please anyone with any info on these issues please help, thanks.
