Here's what I've tried so far, did the CMOS clear and left over night,switched bios, took out cou to see if it was in there right (I'm pretty sure it is now). All these with the sme result. I also hooked up my cou cooler to one of the chassis fan headers and it's working great. I did notice that the chipset fan seemed to be running full power the whole time. I also checked the 4 pin ATX power, by getting another pc and putting it's 4 pin in mine and then try to turn both on, no result so it's not my powersupply.
