Background on machine:
I built it myself. I have built several desktops over the years with no real problems but this build is driving me nuts. It is intended to process and store photos only and is for my old hobby new photography business. I built this in Dec 08 and have been plagued by BSOD's. I never realized it but it never finished any memory dumps or made any minidumps or anything. The more I read I realized what was happening was incomplete. By chance while on a site for my MB I discovered I had my SATA drives incorrectly hooked up on the board and they were out of order. Once I fixed this the machine sped up was less "jumpy" and "laggy". It also started finishing the BSOD memory dumps and started making minidumps.
Before that fix it would BSOD while just sitting there turned on with me doing nothing. Since the drive fix it will run for days with no BSOD's (as long as I'm not using it). It seems to happen when I am online with IE7, but it also does it when i'm in Photoshop or Lightroom. I avoid doing any photoprocessing right now due to the errors but do spend time online trying to find fixes so i think its a coincedence.
I have run memtest86 for days on end with no errors. I have replaced all system files off the winxp disc, replaced/updated drivers for everything I can find. I have downloaded and run a disc diag tool specific for my HD's...all good. I have an updated and often run virus scanner/firewall (Tren-Micro IS2009). Bios was updated. Still BSOD'ing

Some background on the OS. It was installed using a disc that came with my Dell laptop that I later upgraded to Vista. I was told this was OK to use since I bought it and it was only on this machine. Is there anything about it being "Dell" that could be a problem?
I've attatched the minidumps it has generated since it started doing it.
I'm not sure what other info to put right now, but any and all help is appreciated in advance.
