So I just upgraded my mobo (to MA785GN-US2H), CPU (to AMD X4 965), and also hooked up my new Corsair H50 CPU cooler that i picked up for the upgrade. I did not attempt to reinstall windows or anything. I kept the WIndows7 installation as it was on the hard drive before the upgrade. So I then swapped the mobo, CPU, hooked up cooler, and powered up. After loading Windows7, the PC would power completely off at the Windows logo screen. I even got as far as getting into the bios but the PC would still power completely off within 10-15 seconds of booting. I was unable to power back up unless I hit the power switch on the back of the PSU and waited 5 mins. Powered back up and same thing. I should have checked the ram and if they were seated properly. I should have done a lot of things. Instead, I got this bright idea that maybe my 500w PSU wasnt giving enough power so I moved the red switch on the back of the PSU (hmmm, what's this red button do?) from 115 to 230. lol. Powered up, and fans we spinning a little faster than normal, then pop went the PSU. Not a loud pop, but loud enough to hear and I also seen the spark right behind that little red switch (115/230). So the four year old PSU is fried. I tested some pieces of hardware... the Corsair H50 cooler still pumps and all fans still work that was hooked up when the PSU popped. Everything still looks clean inside. No burns. On the back of the mobo right behind the CPU, it's clean. I can't really test anything else until I pick up a new PSU. Won't be for another week until I can. Problem is, I won't be able to sleep until then. What you guys think? Is my new mobo and/or new CPU fried also?
