So the main problem started when my GPU (then a radeon 6500 series) began failing, giving me displaced pixels and visual noise and the like. Then all applications, be it games such as Skyrim or just a program like Word seemed to run slower. I updated the GPU Drivers, The bios, did a complete re-install and HD wipe, and even got a second hand Radeon hd 6870 from a friend. The error still occurs occasionally, the computer is still generally slow, and Skyrim will load but not start a new game. This is the limit of my own knowledge, and I would love some help. I can get the DXdiag file if you need it. Thank you!
