Hello. I suffer frequent crashes, especially while watching online videos. I have been through all the recommended steps before posting. Please help me figure out which driver is causing the crashes. Memtest86 returns no errors, and it seems the crashes occur at the same point every time in the log. I have reallocated the swap space, defragged, cleaned out the dust well, monitored the temperatures with MBM5, run a disk scan. Attached are the last 5 minidumps. My analysis of these dumps all point to "ntoskrnl.exe ( nt!ViDeadlockCheckStackLimits+6c )", but I do not know how to diagnose the problem further. Thank you if you can help with this, I am guessing it is a a bad driver, but have not had luck with updates.
