Hi Aidenne,
Most AMD processors are supported by Core Temp, guess your's is not. You can still likely get the information form the BIOS. You can try Del, Esc, F1, and F2 keys at the very first part of booting (just hold the relevant key down) to get into the BIOS. The key is usually listed at the bottom of one of the first black screens with text during boot start. It should also be listed with the user's manual that came with the computer.
Assuming you have a desktop computer in a tower case, turn off and unplug it. Take the side off (left side, usually about 3 screws). Don't touch anything inside without first touching the bare metal of the case. Discharges static electricity built up on yourself. Use a can of compressed air (from local electronic supplier, Walmart, Kmart, Radio Shack, etc.) and blow the dust out of your computer. Be sure to blow out the heatsink on top of the CPU and the powersupply. You can use q-tips and alcohol to clean the fan blades. With the side still off, plug in the computer and turn it on. Make sure all the fans are turning.
This should clear up any minor overheating problems.
Post back your temperatures and voltages listed in the BIOS.
Best regards,
