hey guys so im having multiple problems which will probably result in me replacing some parts. so my computer isn't detecting a graphics card in the device manager section of windows 8 now that wasn't the case until I had to uninstall and reinstall windows so I don't think its faulty or at least I hope not. however I have a feeling my hard drive is fault which brings me to my second problem on steam I download at 3mbps( I have a 25mbps connection) then the disk becomes busy and eventually it goes to 0mbps and a driver error pops up. however I can detect my hard drive through device manager also the hard drive is almost brand new no more than a few weeks old. I built the computer myself so if any of these suggestions involve taking it apart I can do that theirs a green light on my graphics card however I am worried about my computer hardware's health in general could something be fried and damage other parts like the motherboard?
