Hi, for 3+ years I have been seeking resolve for a single frustrating prolem. I can run my computer for day/hours with no problems. I run a game (a simple one too) and in one area of the game it WILL get bsod with multiple diffent Bug check strings. Kmode+exception_not_handled or IRQ_not_less_or_equal even System_thread_exception_not_handled once. 13 events over the last 3 months. I scan over many bsod threads, I am broken down myself. I have re-installed as per del tech support the operating system 3 times. I got windows 7 and installed that and still problem exists. I purchased new ram, still exists. I do "think" all drivers are up to date as I have tried to resolve this problem via driver re-installs from manufactures to Windows 7 versions. Unable to resolve the problem I am turning to this site to try and aid me in finding the root problem to this life long struggle with bsod. How do we start? I have a program Bluescreenview that will allow me to post you the data of all minidumps. I can start with a run down of hardware then post that and see if that is enough to start your thoughts of what may be at fault. Please also point me out to correct forums location if this is posted in a wrong location. Thank you.

I don’t mind any options as this problem has been with me for 3 years I would love to see it go away at any cost short of a new computer purchase.
