CRC and MD5 errors
When I install stuff on my system, (i.e. oblivion, battlefield 2, hitman 2 etc.) I get crc and md5 errors. it usually affects how the game runs, or the game wont install at all. if it does work, itll crash or freeze up for seemingly no reason at all. I just replaced the motherboard, cpu, and gfx card. the hdd is no more than a month and a half old, my dvd burner is maybe 2 yrs old at most, and all my ide cables and such are brand new. I'm not sure what is causing this since all my discs are fine and seemed to start having issues at the same time.
