msi h81m-p33

My specs are: cpu: i3-4160 motherboard: MSI H81M-P33 gpu: Nvidia Geforce GT 630(planning to change swap it with an RX 580) psu: 750 watts The ram is called kingston hyper x fury 8gb ddr3 1600mhz. The part number is HX316C10F/8. I got my pc prebuilt and I really want to upgrade it to play some...

So i'm tring to update the bios on my msi h81m-p33 but everytime i try to do so it freezes, i just click on the version i want to update to but it just freezes and yes i left it like that for 1 hours with no luck, the mob works just fine but im stuck with version 1.1. any other way i can update...

Hello WOuld it be easier for me to build my own PC or upgrade an exisitng one? Factors to consider Time - No real time frame ( a month or two ) Difficulity - I have a fairly good knowledge of computers basics etc. Cost - Don't want it to be too expensive Thanks
