Question My computer won't boot and the psu is making weird noises

[KasperIversen..]

before i switched cases, the psu could only power a hdd, and after i switched the case motherboard and cpu the psu makes a high pitch when on (The pc isn't turned on) and my motherboard has some led that turns on as well. I've tried 2 different psu's and it's the same problem. Anyone who can help? Also when i turn off the power the psu takes a couple of seconds to turn off like wise the led on the motherboard. The SB_pwr is static red

Welcome to the forums my friend!

Please post your entire system spec including PSU make and model.

Well.. an LED on the motherboard is normal. That means it's getting +5VSB from the PSU (standby power).

Two different PSUs with a high pitched whine? What PSUs are these?

One thing I'm not clear on: You said that before it could only power the HDD? What does that mean exactly? And now that you've moved everything over to essentially a new PC, is it actually booting up into Windows now?

So is the complaint that:

1. The PSU doesn't power up the PC at all (except for standby power)

or

2. The PC works, but there's a noise when it's in standby
