Hp Compaq Pro 6200 I5 2400

I bought a second hand HP Compaq 6200 pro Mt with no Cpu but it does have a pentium sticker so it used to have a pentium, from what i know the chipset on these things can support a 2gen i5 and i7 like the 2400 but im wondering do i need to update the bios first to make the 2400 work? The PC does not post it only turns on, the fans spin and after a minute the fans go super loud and it stays like that, no display aswell so i can't acess the bios

@Silva23,

You need a CPU chip to get further. Read page 1 and 2 completely.

This old circa 2011 machine. It had various OS (including WIN 7 and Win 8.1) Each had a BIOS level specific to the OS.

I had the same problem recently. Your system will post eventually, mine took around 20 minutes, but still, it's very buggy and too slow for the specs. As I bought it from a company that deals with sh and refurbished PCs I mine was in warranty. I sent my PC to the shop and the technician there updated my bios and some hdd firmware.

Fun fact, at the moment of writing this post, my computer is being shipped back to me so I havent seen whether the problem was solved. That guy said it's resolved, but im suspicious as looking through forums, im not so sure if any other than the 2.28 version of bios works :)) and idk which version he installed. 

Im hopping it's going to work and if you are still dealing with this problem i will come later with an update whether it's working or not now.
