Post your computer specs, ask for advice for a new computer or why your old piece of armadillo isn't working, or hell, post your desktop.
I consider myself fairly knowledgeable in terms of computer hardware and software, so please, ask me if you can play a certain game or what kind of upgrades you should look into.
My personal rig isn't amazing, but I built it and I like it
