If the CPU needed thermal paste I would think the temps would be a lot higher on the CPU...I really do not trust the voltage readings unless they are way out. and fans could be the program just can not read it.

How old is the Powersupply?

Hmm the computer should be around 3 years old. The only hardware ive ever changed or modified is adding the Geforce 8400. I also have a bad habit of leaving it on standby and not quite turning it off all the way if that helps.

The only thing I see that is strange in hwmonitor is your 3.3V reading however it is probably a problem with the app reading the sensor correctly rather than your voltage really being that low.

If you can check your voltages in the bios, then do so. The bios is more reliable than any software app.

I checked the BIOS and posted my voltages in an earlier post. I had noticed that none of them fluctuated except for the 3.3v reading, i'm not sure if that is normal however. I'm starting to lean towards maybe getting a new motherboard or power supply not sure if that is a good idea or not though.

If you see either the 3.3V, 5V or 12V values fluctuating in the bios, that indicates a pw supply problem. Some voltages are supposed to go up and down such as vcore or cpu voltage however not the ones listed above.

Really great thanks do you think getting a new power supply would be a wise investment? I'm starting to run out of ideas

It cannot hurt to install a quality pw supply. For the system you list, a corsair builder series would work ok. This one is $49 after MIR. Note the builder series is ok for a basic build however I would not use one with a high end video card ie nvidia 570 or ati 6870, etc.
