Is my power supply the problem?

Question

When I try to turn on my computer, it does not come on. I've checked the power cable, and power bar and confirmed they are ok. The monitor and printer turn on, but nothing happens with the computer.

A slight buzzing sound can be heard at the back of the machine, near the fan (however, neither the fan or hard drive run).

Does this mean my power supply unit is fried??? Are they expensive/difficult to replace?

Thanks.

This could mean that your power supply is fried but it could also just mean that the connection to the motherboard is come loose or the drive interface is not connected properly .Both situations will power up the printer and monitor but the computer will stay in an almost lifeless state

Unless you are experienced in fixing computers do not attempt to diagnose/fix this or the problem might turn into something really serious Instead, take it to a tech.

If it is your power supply, they are relatively cheap parts to replace.

If it is one of the other situations described, once the connections are fixed, it should be fine
