Hello, community. I've been having problems with this computer from day 1. I bought a debranded HP Pavilion desktop off of Newegg about 5 or 6 months ago. After numerous memory errors and failures, I determined that the RAM slots were faulty. Of course, the only solution was to replace the motherboard. So I bought a new MSI 760GM-P23 from eBay, and had the guys at the local computer shop install it. I got the computer back today, inspected the inside of the case, checked the wires... everything seemed to be in the right place. I hooked the PC up and booted it to find that the CPU fan was at maximum speed. I tried booting to Ubuntu and setting up pwmconfig, and only 1 of the 3 listed PWMs actually controls a fan, which is the rear exhaust fan. I booted to Windows and fiddled around with Speedfan, which listed 5 PWMs and the GPU fan speed. Again, only 1 PWM worked.
I've tried disabling C&Q, and I've tried setting "CPU Smart FAN Target" to all the lowest settings and rebooting, but nothing seems to console this helpless fan. I think it may have something to do with it being a 3-pin fan(?), but I don't know much about that type of stuff. The old motherboard (FOXCONN 2AB1) worked just fine with the CPU fans. It would be at a fixed speed upon bootup, and it didn't automatically regulate the temps, but at least I could control it with 3rd-party software. So I'm out of ideas. Any more you guys can offer me?
Also, for some reason, I cannot hear any audio with the onboard sound chip. I haven't investigated much on this (mostly due to the loud fan clouding my thoughts). Both the stock Windows drivers and the Realtek-provided drivers don't seem to solve the problem. I've also tried on Ubuntu, but all seem to produce the same symptoms: audio is playing, the OS *knows* there's audio playing (volume meters work), but I cannot hear any audio through my headphones. I thought it could be a wiring problem, so I checked again. AFAIK, the motherboard is connected properly to the front panel. I hope you guys can enlighten me.
Sorry for the lack of info, I do know much about computers, but motherboards are definitely not a strong spot. I'll try to provide all the information needed. Thanks for the help.
