Hi, i have an hp omni 200- 5120it all in one pc with a 2aa2 motherboard, i tried to install a core2 quad q8400s cpu, despite is not supported and the pc seems to start regularly but sometimes the os start and sometimes it locks on the boot logo, i tried both linux distro or windows, the bios is upgraded to 6.14 version, is it possible to solve this problem?
