You gave a quick answer to someone else regarding something similar so I thought I would ask. I am getting blue screens indicating Stop errors that identify either “KMODE_EXCEPTION_NOT_HANDLED” in win32k.sys or “Driver_IRQL_NOT_LESS_OR_EQUAL” in NV4_MINI.sys. Both indicate memory dumps. I have identified the nv4-mini.sys as my NVDIA video driver which I reinstalled with the most up to date but it came back as if it it never left. The consistant task seems to be any intense video game or picture viewing software I use hoses it up. I get a blue screen and it sometimes counts up to 99 and reboots. Other times it just locks saying if I recently installed some hardware or program to check with my administrator. Is there something you can say to give me some direction or possibly have an idea what may be causing it. I have OS 2000 sp3, and all my hardware drivers are up to date. Also, what would cause the win32k.sys file to hose up too? Thanks.
