I just recently rebuilt my computer with an xfx 750a sli mobo, amd 5800+ cpu, thermaltake cpu cooler/fan , wd 320 gb HD, Ultra LSP 650 PSU...the only thing I have that isn't brand new is my dvd burner and case fans. Immediately I had trouble with cmos checksum so I replaced the battery and with persistence I was able to install xp home. I immediately installed all necessary drivers that came with the mobo, and commenced with the windows updates (sp 2, sp 3, and all other high priority updates). All throughout the process I encountered a number of different errors ranging from internet explorer errors (I tried V.6, V.7, and V.8 and had similar random errors with each) to bsod of many types pointing to drivers, memory corruption, faulty hardware, internet explorer dll's, ntdll.dll, and more. I also thought I had trouble with one stick of ram in particular (tried in different slots and in combination and solo and system was consistently unstable/ would not boot or load windows properly) but memtest 86 v 3.5 found no errors on either stick??? I ran memtest on the stick that is currently installed for 13+ hrs with no errors. I had trtouble with MS silverlight dll's, IE dll's, xp dll's, NV driver files, mem. corruption, etc etc etc.....No matter what updates or rollbacks I did I kept getting errors, the particular fault just changed. I reloaded windows hoping that something got corrupted in the first installation but I'm still experiencing the same type of issues. I just reinstalled windows today so I only have 1 minidump but I have many error log entries. I'm currently running sp2, IE 7, no secondary programs except registry mechanic which hasn't helped anything. Latest mobo drivers from nvidia/xfx and basically every windows update except sp3. I don't have a cpu temp monitoring program, but I've checked it in bios a number of times after running different programs and the highest I've seen it is 50C. I need help figuring this out as it is seemingly random and varies so much. I get alot of IE errors and less bsod's (only 1 in the last 24 hrs since xp reload but I was at work all night so no strain on computer) I attached the minidump I have and a few of the diferent error log entries. I've never seen such a range of different errors, Is my mobo bad, or ram bad and memtest can't detect it or what? I'm desperate and would greatly appreciate any help anyone can provide, thanks in advance.
