hey guys, for the last week or so...and especially today, my computer has been crashing and i get the blue screen with the message telling me windows had to shutdown, etc. i have had variations of the following messages today: "...caused by file: alcxsens.sys PAGE_FAULT_IN_NONPAGED_AREA tech info: ***stop: 0x00000050 (0x8A111505, 0x00000001, 0xBA1F3688, 0x00000000)" "IRQ NOT LESS OF EQUAL" "BAD POOL CALLER" ive read the stick that i think was about these types of crashes, i cleaned all the dust and debris from inside my comp. i have also run the disk defrag, but i still get this problem. my cpu is not overslocked, and now its sitting on an average of about 35-40deg C, my HDD is about 40-45deg C. in my event viewer i have a lot of errors, such as "application errors", "application hang". "ESENT", "MSIinstaller". here are a few of my recent mini dumps and the event logs. any help is greatly appreciated. im running xp with a 3gig CPU 1gig RAM and an 80gig HDD.
