I have a problem with my computer. The last month I have had serial problems with different kinds of BSOD's. First, my system: MSI P965 Platinum, Bios 1.7 Intel E6600 Rev B2 @ 3.15 Ghz OCZ OCZ2T8002GK @ 1.05 Ghz MSI ATI X1950 pro (Ram is underclocked with 7 mhz, Dont know why..) WD Caviar SE16 WD2500KS (SATA) Maxtor DiamondMax 10 250 GB (IDE - Slave cable position) Lite On DVD-burner (IDE -Master cable position) Fortron Blue Storm II 500W PSU (Makes screeching noises in standby) Creative SoundBlaster Live! 24 bit External Microsoft Windows Vista Ultimate x64 Okay.. Here we go.. My harddrives and DVD drive are controlled by a Jmicron controller. About a half year ago I shifted from Windows XP til Vista because of the evil BSOD.. That was probably my Soundblaster's fault. Then I shifted to Windows Vista x64 where, as I can remember, I had the same problem, maybe with a couple other BSOD, it became very instant and I shifted til Windows Vista x86, where I didnt had that many problems with BSOD's.. But Now I have shifted back to X64 and after 14 days of usage I got A LOT of BSOD's.. Here are some of my BSOD's: http://www.fuscrew.dk/incomming/BSOD/PICT2740.jpg http://www.fuscrew.dk/incomming/BSOD/PICT2741.jpg http://www.fuscrew.dk/incomming/BSOD/PICT2742.jpg http://www.fuscrew.dk/incomming/BSOD/PICT2744.jpg http://www.fuscrew.dk/incomming/BSOD/PICT2746.jpg I updated my BIOS and my Jmicron devicedriver and now I only get the Bad_pool_caller BSOD, like this: http://www.fuscrew.dk/incomming/BSOD/PICT2740.jpg As I can read on the Internet, this is usually caused by a device driver. Installing "Driver Detective" I can see that the only driver I that arent "up-to-date" is my Intel ICH8 device drivers. Downloading and installing the drivers from Intel.com did not help alot, because the x64 drivers is older than the x86 drivers on their website.. Another posibility is my Realtek MSI driver who is screwing my computer. An agument for that could be that I usually get my BSOD while playing TF2 with a Skype conversation open. It could also be a Hardware error, but I have tested my Memory with memtestx86 and i gave me random results with random errors.. What can I solve my BSOD and what do you think causes my BSOD? A solution could really make my day/year/christmas! PS. Just did a Prime-test and I got an error after 17 minutes. What could have caused that Error?
