I've replaced graphics cards, sound cards, ethernet cards (in the old days lol), and hard drives. I'm waiting for the parts to arrive for my most ambitious project to date lol: adding RAM and a SSD and replacing the optical drive with the old hdd. So I may be shopping for a new computer sooner than I think when it all goes south lolI probably just need to get something simple to practice on. I think the motherboard and fan scares me the most lol
I'm sure most of us here could lend some assistance via this thread to help you out of a jam
