After upgrading to a Corsair HX1200 i've started to have boot problems, the computer gets into a boot loop, shutsdown and powers on again, I manage to get the computer to boot only after several clear CMOS. After a boot I load a bios propile and boot into windows, after a seccessful boot into windows i can use the mechine as usual like nothing happend before. This only happends after a long shutdown time, the PC reboots and shuts down and turns on without problem for short down times, I've tried replacing the CMOS battery it didn't help.
