Thank you all for the ideas... I have been having other blue screen issues over the last two week and the PC has been entirely down. I got it up and running again tonight. so here is some quick info on the setup. nothing is overclocked here. have removed all PCI cards from PC. I am also having "power_driver_state_failure" on some shutdowns. when using windows normally, sometimes my Internet explorer window locks up. once this happens, i cannot open a new instance of the program. i get an houre glass for 3 sec then nothing. My system monitor / processes show i have iexplorer running but the window never opens for me. when this happens and i go to reboot, the PC nevers shuts down and i will now get the "power_driver_state_failure" after 5 min or so. I have already reinstalled vist. cluberti, THANK YOU for taking the time looking into this issue. as and FYI, I had this issue BSOD: irql_not_less_than_equal before i installed SEP. I have not been able to find any updates to the SW besides the new virus def i get daily. as for the chip set, I tried to reinstall the latest drivers but the file you found in question remains the same date and ver after the update. ans my system is wirless, im not using the wired ethernet. i think that what this driver is associated with nvm60x32.sys. Things i have done or happened since cluberti read the dump for me: As i stated above, the PC was dead for about a week, i encountered Lockups, constant BSOD IRQ_NOT_LESS_THAN_EQUAL and finally BIOS error code. i am using a evga 780i MB, POST error 26, 26 Clock Gen Init onboard clock generator and sensor. and i also started to get POST error on my RAM. I pulled all 4 sticks out, and cleaned them. looks like the contacts were dirty. that problem seems fixed. then i had to replace the video Card and the PC booted again. so that is where i am now. cleaned memory and a new vid card. so far NO IRQ_NOT_LESS_THAN_EQUAL problem byt i need more time to verify the issue ig gone, however i still have this BSOD "power_driver_state_failure" i need to figure out. i hate computers...
