CPU overloaded or throttling?

[Chase Catalano]

My build is about 6 months old, but has recently started exhibiting a problem where the monitors (all 3) go black, and come right back on. A week ago the computer just died, and I ended up replacing the heatsink (fan died), thinking that was the overall cause of the problem. Well, it wasn't, as it's still happening. I completely removed the GPU drivers (Radeaon r7 200 series) and reinstalled updated drivers, and the problem persists. Today I downloaded HWMonitor to check temps and clock speeds. Temps appear normal 19-43 degrees C for CPU and 49-55 for GPU. However, each core in the CPU (AMD FX quad core) is running between 1406-3917. I noticed that while streaming a TVshow, and playing online poker, these clock speeds get erratic and all 4 will spike to the high end of the range frequently. All the while the monitors are doing their annoying blinking game. Is there a correlation? Are these normal clock speeds for the given CPU? If this is/or might be the problem, how can I go about fixing it? Thanks in advance anyone/everyone!

you said your fan died while the computer was on?

it sounds like the computer shut itself off however it could have taken damage with the sudden lack of air flow i will look around and get back to you however

whos the manufacturer for your graphics card

Yes, while watching a movie. I don't know that the fan completely died. I do know that it was running hot, and when I removed the heatsink and tried to manually rotate the fan, it was sticking. I replaced the heatsink with a much better one, and aside from the monitor issue, everything seems to be running fine.
