If it's a generic power supply that came with your computer case, then it's definitely possible that it's dying a slow death and causing your other problems.dwharton said:I am having trouble with computer hanging up and it happens after start up...things can be running for a while but then a noise...sort of a soft grinding, but not really abrasive grinding if you get my drift, comes from the power supply. The fan is running smothly and doesn't change during the noise. i have isolated the noise to the supply. Hav e stoped the CPU cooling fan for example. Am I in need of a new power supply. Seems a weird thing to fail. No? could there be any relation to hard drive problems or is the noise a pretty determining factor that something is a miss with the power supply?
Aside from the typical whrrr sound coming from an exhaust fan, a power supply should not be making any sounds.
Can you open up the computer and tell us what make, model, specs are for the current power supply? (There should be a label on the side of the power supply.)
Also, what is the make and model of the computer?
