I'm thinking I have a hardware issue but can't seem to pinpoint. The other day I was using windows and a program stopped responding or it was taking an extremely long time to open. So I rebooted the pc and it took so long that it never made it back to the windows log in screen. So the next thing I tried was to do a clean install of windows to see if that would help but that ended up also taking forever because the setup was also running extremely slow and never made it completely through although I imagine if i gave it several days it MIGHT make it? I've switched out hard drives and ram sticks to see if either might help but nothing has changed. The only strange thing is that at some point in switching out the hard drives, my old one suddenly stopped being recognized by the bios screen and when I switched to the new one, same sata port and power cord, it recognized it but the pc still has the extremely slow issue. Any info or help would be greatly appreciated. At the moment all I can really do is boot to the bios screen.
