Description: I installed everything in place and there was no power running. I changed the Ram Positions to A2 and B2 and they turned on but the CPU fan didn't turn on. So I changed it to the chasis fan conector and then it did turn on but after a couple of minutes burned one of the rams. Obvious I shutted it off and left it there.
So I bought another Motherboard the Gigabyte GA-965P-S3 and the same problem happens nothing turns on and this time I am only using the Ram that is good. I have checked all the cables to the front part of the case. everything to be connected correctly and still nothing. Any help will be greatly apreciated. Thank you for reading.
