trying to upgrade cpu but no display

[stg44prodo]

i recently bought a prebuilt desktop (acer aspire m3300) and i wanted to to make some upgrades to the cpu (amd phenom ii x4 810) and put in an fx 6300.
however when i turn on the pc all the fans spin, but i get no signal to the monitor and my keyboard and mouse dont light up.
I already updated the bios to the lastest version available on their website (P03.B4L)
this version was released in 2010 and the fx 6300 was released in 2012.
does the motherboard support the cpu or not??

Fx processors require AM3+ platform. phenom II processors use AM3 (no +) platform. No BIOS changes can affect that. Ready made, brand name computers have very restricted upgrade path.
You could exchange that processor with a Phenom II x6 like 960T and higher with almost same performance as Fx 6300. Or highest one like https://www.cpubenchmark.net/cpu.php?cpu=AMD+Phenom+II+X6+1055T
