The "new" processor is Intel Celeron (SL5XS) 1.2GHz. http://processorfinder.intel.com/Details.aspx?sSpe
However; when I mount it in and boot up my PC, nothing happens. No beeps, no text on a screen - nothing... HDD- and Power-leds are working tho and DVD-drives light flashes couple of times but then it's all silent.
That's 100% sure that the Celeron processor is not damaged. That's guaranteed.
Is it just that my motherboard doesn't support that model of Celeron or what's the matter?

The Deskpro EX comes with two different chipsets the 810e and the 815. The 810e motherboards only support up to 866 MHz processors.
You have the 815 chipset according to your information. The 815 chipset supports up to 1.7 GHz Pentium III so I would expect that it would support a 1.2 GHz Celeron processor also. However none of the Deskpro EX models came with Celeron processors over 700 MHz.
Hope this helps.

1. The Celeron 1.2 is designed for FC-PGA2 and the Compaq system board has an FC-PGA socket. The processor is not compatible with the socket.
2. The chipset is running the FSB at 133 MHz. The Celeron is designed for a 100 MHz FSB.

Unfortunately Steven is right as far as I found more information by myself. :/
But... Fortunately that doesn't hurt much financially because the processor was very cheap. Just thought to give it a try and ask for information.
If I'm about try a processor change again in future, could you give me information what exact processors are supported by my motherboard/socket/BIOS? Thanks in advance.

The BIOS apparently recognizes up to 1.2GHz with the latest download:
However, many Compaq computers will work fine with processors not correctly recognized by the BIOS. You just install a program that skips the error message when booting up. It's here:
