PC will no longer boot. Fan issue?

krazykraka · Jan 2, 2015

Hey All, my PC won't boot up anymore and it started making an odd sound with one of the fans. I don't think it's the hdds, but I'm not too sure. I made a youtube video of the noise in question:

fans wont make your pc not boot up it has to be hardware issue.
1st thing to check is usually the PSU.
dont bother with Hdds even if theid be broken pc would go into bios.

Yea I figured it wasn't the HDDs. There's no beeps and it won't get even get to the boot sequence. I'll check the PSU and go from there. Thanks

The PSU is most likely faulty. But the motherboard may be faulty (as well).

Best way to test is to use another known working PSU. This will confirm or eliminate the PSU as being faulty.

If another PSU is unavailable, then the PSU can be tested using a digital multimeter using the procedure here. This procedure tests the PSU while disconnected from the other components (unloaded). If PSU the voltages are found to be OK, then the PSU is likely to be OK, but it should be tested again after it has been reconnected to other components. This will test PSU voltages while under load. If the PSU voltages are too high, too low, or there is no voltage, then the PSU is faulty.

If PSU voltages are still OK, then the motherboard is probably faulty. If PSU voltages are way too high, too low, or there is no voltage output, then the PSU is faulty.
