On page 13 of this manual: Microprocessor (varies by model type): Intel® Pentium® 4 processor with 256 KB or 512 KB of internal L2 cache memory and Intel NetBurst™ micro-architecture.
It seems that the computer's motherboard does not support Intel P4 processors with more than 512 KB of internal L2 cache. That's why your P4 2.8GHz/1M/533 Prescott processor did not work. You will have to either buy another processor with 512 KB L2 cache, or replace your motherboard with one which supports the new processor.
It is normal for a board to beep if there isn't any RAM in it. This is due to the POST process checking to see if everything is all right, and finding no ram.
to check the board, ll you can do, is make sure the CPU is compatible with the MB, also try putting an graphics in the machine. If it displays, great! Then you know your onboard graphics are not woking or disabled in CMOS. If it doesn't show anything, and you know that the RAM is not faulty, and the CPU is compatible, and you plugged out all CD-Roms/HDDs, then either your onboard graphics are faulty, or your motherboard is dead.
