Replaced PSU, now disk 100% in task manager

[kpoohs]

My PC’s power supply was on its way out so I replaced it with a EVGA 450 BT (450W). But after replacement, my disk is always showing 100% usage even when the processes are most generally in 0.1 mb ranges. The power supply that came with the PC I was replacing was a L300NM-01 (300W).

Now when I first turned the computer on after putting in the BT, things did run slow but after restarting the speed has improved back to normal but disk speed still says 100%.

I switched the cord between the DVD drive and the GPU Incase it was the cord, still the same. I also made sure all the cords were in all the way.

So does this mean I need to replace this power supply with a higher wattage? And if I do where did I go wrong picking this PSU so I won’t buy the wrong one again

How do you know it's at 100%? Task manager? Is it an HDD? If so...you should be able to physically tell it's at 100%....it will be making noise etc.

I guess my point is....IS is really at 100% or is Windows just telling you it's at 100%.

Also, replacing the PS should not have caused this. I'm not saying that it didn't....but it is not normal.
