Well this is totally messed up lol. After a week of computer crashing BSOD's/ PAGE_FAULT_IN_NONPAGED_AREA / DRIVER_IRQL_NOT_LESS_OR_EQUAL( this one listed a problem with realtek, RtkHDAud.sys), and a few restarts with no BSOD.I have ran Memtest86+, always finds no errors even when ran overnight. Have ran ORTHOS set to torture cpu and ram, never a problem. Now brings me to the weird stuff, aggrivated to death and back I decided to try one last thing, The pc im working with Has 2x512 corsair xms2 ddr2 800 ram(bought a duel mem 1gig kit) I pulled one out and ran my pc gaming for 2 hours not a crash( ran game slow as heck but no crash) I then swapped the one left in the pc with the one i pulled, same deal no crash for approx 2 hours. Then im thinking wth I then popped both back in booted up started game as soon as game loaded and i started to play bam BSOD PAGE_FAULT_IN_NONPAGED_AREA, So harray I now know its my ram but, what i wonder is this: Anyone else had this problem or even heard of something like this before? cause i know i have never heard anyone talking about a problem like this with ram? What could make it do this?
