Windows 10: Bad CPU or Something Else???

Hi all,

I am having this issue with an old PC that I was trying to resurrect as an "Internet Browsing/Youtube" computer for our house guest and the specs of the PC is Intel Core 2 X6800 + Asus P5Q (Latest BIOS 2209) + 8GB RAM + 240GB SSD.

Installed Windows 10 Pro (1909) just fine and was able to use the computer for about a week so I decided to upgrade the CPU to Quad Core to make it more capable of streaming 1080+ videos. Ordered a used Intel Quad Core Q9400 on eBay and it arrived yesterday so this morning I swapped out the old X6800 to the Q9400.

Booted into BIOS just fine and I was able to do a BIOS reset and reconfigured everything from scratch.
But just when I'm about to install a fresh copy of Windows 10 (USB) the computer will freeze as soon as it reached the "Loading Files..." screen and I had to force restart the computer.

At first I thought it was just a bad USB drive so I tried booting Ubuntu Linux using another USB and the system will again freeze as soon as the system starts loading.

Ran out of ideas so I tried swapping back to the old CPU (X6800) and I successfully installed Windows 10 and was able to boot Ubuntu from USB as well. So I guess the CPU is the culprit right?

Contacted the seller about my issue and he told me that he tested the CPU before sending it out and it was good and since the computer successfully POST'd and was able to get into the BIOS so the problem was with my hardware.

So what do you guys think? Is it a bad CPU or something else?
Thank you for your inputs...

:)
