Hi, I have built my new PC and I'm having a problem with the PSU fan, it starts when i power on but then stops at the bios which shows a PSU fan error. I can stop the error showing but the fan doesn't come on. I can reboot my PC and it will start with no problems but I'm a bit concerned that it might shut down if I leave my PC on when I'm not there. Ive flashed the bios to the newest and Ive also shut the PC down and moved the jumper then moved it back as someone suggested but that didn't work. Ive unplugged the fan and checked the pins and all is ok. I had the fan working ok before in my old setup. I do not understand the settings in the bios to change them to manual and just about everything is running in auto mode. I'm not into overclocking but if there is a tweak to get the fan running then I would give it a go. I'm not super efficient like most of you on here so if anyone has any advice please do is basic terms.
Thanks
