I have a really terrible pc Intel Atom 330 processor and integrated graphics, I decided to upgrade so I bought the r-H81M motherboard, intel pentium g3250 processor and AMD Radeon R5 230, I know that's not very strong pc but will serve for mc,now problem is that i do not know what to do after installing the hardware. on youtube and find bunch of hardware video but do not know what to do after i first turn on the pc
