Regarding the fan, loud noises are generally indications of bearing failures -- and that is a serious issue as your PC will overheat almost immediately and shut down as a result.

That being the case, you need to get the fan replaced and such repairs can be very difficult and risky to perform, depending on how much stuff has to be removed in order to get to the fan to replace it.

For such repair estimates, you would need to contact an HP Repair or Service Center.

Since you live in the U.S., here is a link to the HP Service Repair Centers:

Since you live outside the U.S., here is a link to HP Service Centers, by Country/Region: https://support.hp.com/in-en/service-center

If that link does not provide useful information, use the main HP link:

Regarding the black screen ...

Software failures will generate on-screen messages, usually about not finding an Operating System or not being able to boot. When the screen is blank, the PC is experiencing a major hardware failure.
--------------------
To determine the cause with hardware failures, you have to be able run diagnostics. We have no way of accessing your PC from here, so we can not do that for you. You have to do it yourself.

You do this by pressing the Esc key repeatedly when rebooting and then, when the HP Startup Menu appears, selecting Diagnostics (usually F2) and letting it run.

If it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do because we have no way of accessing your PC from here to run diagnostics or repair hardware.

You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it.

--------------------
If your PC is still under the original one-year HP warranty, or if you have purchased an extended warranty from HP and this is still valid, then having HP do this is an inexpensive option for you. In that case, you should contact HP Customer Support to see about having it repaired or replaced under warranty.

Here is how you can get in touch with support:
Step 1. Here is the link: http://www.hp.com/contacthp/
Step 2. Select the product type.
Step 3. Enter the serial number of your device or select let HP detect your product option.
Step 4. Select the country from the drop-down.
Step 5. You should see the HP phone support number or Chat option listed.

--------------------
If your PC is no longer under warranty, then it will cost you up front to have HP examine your PC. If you want to do that, you will have to contact an HP Repair or Service Center to see if they can examine the PC to determine the cause(s) of the problems, if it can be repaired, and an estimate of the repair costs.

I already provided you contact information above ...

Good Luck
