Specs: AMD X2 3800+ 2 x 512MB RAM = 1 GB OCZ Radeon X850XT Asus A8N5X (BIOS 1003) Windows XP SP3 I initially tested my RAM with memtest86 as follows: Stick 1 in Slot 1 = Pass then Stick 2 in Slot 1 = Pass then Sticks 1 and 2 in Slots 1 and 3. (Dual Channel) = Fail on 4th Pass I currently have Sticks 1 and 2 in slots 2 and 4 (Non Dual Channel). I installed drivers through windows update after install the nForce 4 package from the nVidia website. The latest package they have listed doesn't contain NIC drivers (odd) so I used the second to last driver set for the NIC, and then used windows update for the rest. I still have some uninstalled devices, (i.e sound, which I thought should have been included in the nForce package but ill check that later). The Blue Screens in order of Received. 0x0000008E (0xC0000005, 0xBF829BF4, 0xA7CBAAA0, 0X00000000) win32k.sys I looked this up and on one of the Microsoft sites, it said it potentially could be cause by a third party remote software / driver, so I uninstalled RealVNC right away. I thought I was done, but little did I know. 0x000000C5 (0x00000004, 0x00000002, 0x00000001, 0x8054BFD2) Something about Special Pool I ran Driver Verifier on all drivers with standard settings and then got 0x000000C1 (0x89292F50, 0x8929274D, 0x005BC0B0, 0x00000023) Special Pool Detected Memory Corruption after about 10 minutes of uptime. I then turned off driver verifier and began typing this (on another computer) only to get 0x00000024 with the file listed as ntfs.sys. I am going to run a chkdsk next and then defrag I suppose to address the latest BSOD. I am not exactly sure how to proceed next. Should I run memtest86 again on the 2 sticks in slots 2 and 4? Any suggestions or help would be fantastic.
