I've got an outdated computer, and I'm looking to milk it for a couple more years (so please guys, don't suggest 'buy a new computer' unless you really really mean it, k?). The model is sr1750nx (a simple google search will turn up all of the info via HP's website). I plan to install a Radeon r7 240 graphics card -the easy part, right? ..and to speed things up I'd like to upgrade the processor from the stock Athlon 3500+ to a dual core 4800+. I've done some homework and as far as I know the new cpu would physically fit, but my fear as listed in the heading is the BIOS. I've read on a few sites all about the boogeyman that turns computers into paperweights when it is changed or updated.
