About 6-7 months ago, my power supply inside my DIY PC started ramping it's fan to 100% and stay there. I remember accidentally hitting a power switch with my foot that shut the PC off, but the ramping fan problem started about 2 days after that. Most of my MOBO utilities are up to date, but the BIOS isn't. Could a error within the BIOS be causing this? I can't remember where it was, but I saw a fan speed for my PSU. It told me it was running at 3000RPM's and at 100%. I've also turned the computer and the PSU fan wouldn't ramp up at all for about a good 10min. But, after that 10min of blissful silence, the fan ramps up and doesn't go down. I'm hopefully upgrading my PSU soon, but I wanted to know if there was any way to fix this without RMA'ing the unit or just get the new one.
