I have a custom Athlon 64 3000+, 1 gig ram, radeon 9800 pro, and an MSI k8t neo fsr. The problem is that my cpu temperature keeps switching drastically (by about 20 degrees) every now and then when i turn it on. For example, today my cpu temperature is at around 47 degrees C, and it will idle in the high 40 range for the rest of the day. However when i turn it on tomorrow it may be in the high 20 range all day. It has been switching off between these ranges about every other other day. Is this a misread or is there something seriously wrong with my computer?
