Hey guys. Yesterday I was messing around in speedfan because my CPU Temps were WAY too hot for my liking so I attempted to change some settings. When applied my new settings, for some reason the CPU fan shut off. In order to save my CPU from overboiling. I quickly turned off my computer. However now it won't start at all.
I initially thought it was a CPU problem so I bought a new cpu to switch in. However the same issue still arises, the computer will not get to the bios screen, it just hangs with no display. I then checked my power supply, I used a different power supply to power just the CPU, MOBO and GFX card. No dice. I reset the CMOS manually and tried using memreset as well (Asus M4N75TD mobo, 1045T Phenom x6, 12 GB ram corsair 1600mhz, 500 gb hard drive, Windows 7 64 bit, 2 3.5 bay DVD/RW drives, GTX 460 Factory Overclocked)
