My snap has always been a little bit suspect at times, but the past month or so it has been quite horrible and now i know why. I have 4 32 bit games loaded on my computer, 2 of them flight simulator and grand prix racing work flawlessly , silent hunter III and links are triggering a rundll32.exe to show up in the task manager processes the second i start them. It is bringing cpu usage up to 100% and it stays there even after the games are closed.
I have tracked it down to C:\windows \syswow64\rundll32.exe which is a valid windows file for 32 bit programs, i have checked it for a virus, ran Malwarebytes at it, and found nothing, computer is as clean as a whistle... ran sfc /scannow in msconfig to see if it was a corrupted file and get nothing.
Now that i know whats doing it i can workaround it by going into task manager and ending the process, as both games still work fine after closing it, cumbersome but effective as cpu usage drops to 3% and snap returns to a little bit suspect from horrible.
If anyone has experienced or knows how to correct this ...i'd love to hear from you.
