my pc was running slow and showing me boot disk could not be found or is not working error after startup screen. presseing f2 got me to diagnostics tests and it said everything was fine. i went to my resource moniter and it showed system running at 9 million b/sec for a few minutes under the disk tab. i think it may be issues with my optimizers or hdd but the seagate tools isnt compatable with windows 8. any ideas to help?
