I have been having issues with crashing with some games, mainly mods which worked perfectly on my previous system. My first course of action was to reinstall the mods which it still crashed then I scanned for errors on all my storage devices and it came back no errors. I also checked my storage devices with crystal disk info and they are all in perfect working condition. I have ran tests with my ram with windows memory diagnostic several times and it always comes back with no errors. The last thing I thought that may give me answer with this would be to use memtest86 and see that helps but the problem is the flash drive I mounted it on to, is unable to boot into memtest86. I keep on getting this blue screen like error that says that the device I am trying to boot off of is unreadable and needs to repaired.
