Hi and welcome.
If you feel able to..
Check inside the Pc.

Turn the Pc off - unplug from the wall socket.
Once you have opened the case.
Touch the metal case to discharge any static.

Remove any dust - do not use a vacumm cleaner, too much static.
Check that all fans are free of dust and will rotate.

Remove Ram - Video cards etc and then Reseat in the slots.
But first - clean the copper connections of the Ram - Video cards with a pencil eraser.
If more than one Ram stick - use just one at a time, as a test.

Put the case back on the Pc - and see if it will boot to the desktop.

Try all the suggestions from Blues Harp but if no improvement I would suspect from that clicking sound that your hard drive has a problem.

Use another PC to make a boot disc to test the drive, as follows:

Identify the make of your hard drive and then use one of the links below to get the manufacturer's diagnostics for ISO (CD) not the one for Windows.
When the download is complete right click the file and select Extract Here and burn the image to a CD.
In Windows 7 right click the extracted file, select Open With, then select Windows Disc Image Burning Tool then follow the prompts. For all other versions of windows (if you do not have an ISO burner) download this free software. ImgBurn
Install the program and start the application. Select the top left hand option to burn image file to disk and then on the next window click on the small yellow folder icon and browse to the file you have downloaded from the links below. Then click on the two grey discs with the arrow in between (bottom left) and leave it to complete the operation.
Boot the PC into the Bios setup and set the CD/DVD drive to 1st in the boot sequence. Insert the disk in the drive then reboot and the disc will load into dos.
Excelstore
Hitachi/IBM
Samsung
Seagate, Maxtor & Quantum
Western Digital
Toshiba/Fujitsu
If you have a Toshiba/Fujitsu hard drive I would suggest the use of the diagnostics from the Seagate link as this will work on all makes of drive and on any OS.

I have seen this problem few times, slave the hard drive to other machine using chkdsk /r /f fixed for me
