PC made loud noise sound when starts up

Hi,

I have a client who had experienced his PC made loud noise sound when he rebooted his PC.

It has happened once not every time he reboots the PC.

I tested hard disk and other components but found no issues.

Would there be other ways to find out why it made that loud sound? I can only diagnose remotely.

since you give no specifics -  the best we can do is guessing, and offer general help:
-look in event viewer for errors
-measure the PS output voltages during operation, and check if they are within limits : 5% -  or replace the PS
-use the eliminating  system to find the bad part : replace parts one by one, or in groups : ram, disk, cd, cards..

what PC is this ? model, or specs?

A loud sound?
Lol how can we determine that
I appreciate you also have not heard it remotely, but a loud sound could also be a stuck fan over the heat sync or a fan over his video card.
The fan inside the PSU.
Needs more details just like if you bring the computer in to a shop, what type of computer model brand laptop or desktop.
Laptops have a different set of problems.
How old is it?
Any symptoms showing?
Ageing parts on the motherboard exploding capacitors?
If there is no mention of hardware failure or boot failure, no BSOD
you might not be able to diagnose, you'd need eyes on.

If the Hard Drive manufacturers drive test passed you can rule that out.
Did your client leave a CD/DVD in the CD/DVD-ROM drive on startup he may have forgotten about?
As Merete suggested it was possibly a Power Supply or Cooling Fans bearing not being lubricated at the time.

what kind of sound is it?  like a fan touching something; or a bearing grinding?

It may even have been a wiring harness pressing temporarily against a fan. You would have to remove the cover for a visual inspection and check that everything is where it's supposed to be.

Our client did not know what kind of sound it was. There was no logs related to this event. I might just need to wait for this to happen again when I am on-site. Thank you for your answers!
