PC makes peeping noises and seemingly rejects old and mew CPU's.

Hello, i have an Omen PC (880-117nz). I bought a new CPU, which is Intel i7-9700k. Before i had an i5. I switched out the i5 with the i7. I removed the cooler, took out the i5, put in the i7, put some thermal paste on it and put the cooler back on. i plugged the cooler in and plugged my pc with cables. I turned the pc on, only for the cpu fan to be very loud and the pc making peeping noises. (3 long ones and 2 short ones) So i turned the pc off again and tried to solve the problem. I unplugged a lot of cords, i took out one of my RAM sticks, but nothing worked. I decided to put in my old i5 again, but then my pc started doing the same things, although this didnt happen before i switched the cpus. My Monitor does not display anything and i am honestly lost. I appreciate every kind of help!

@Filip2057 , welcome to the forum.

Here is the Product Specifications page for the computer: https://support.hp.com/us-en/product/omen-by-hp-880-100-desktop-pc-series/18695893/model/21440882/do...

Look at the section titled "Processor/Processor upgrade information".  There is a list of compatible processors and your i7-9700K is not on the list.  HP has their motherboards made to their specifications.  They use them in many different models with as many configurations.

If you are still getting the beep code with the original processor, you should clear the CMOS.  This may solve your problem.  If that doesn't solve the problem you should make certain that you have the thermal paste and processor installed properly.
