Wow this thread blew up eh?
Last night I began tinkering around with it again. I switched the GTX out for my 9800GT and I was still having issues. I tried using different ram and then everything started falling into place. The new ram is definitely faulty so I RMA'd that and will be getting a new pair in a few days.
HOWEVER, the issue ended up being a bios problem. I looked up the Gateway model number and noticed that a new bios revision was released about a year ago. I looked up the read me for it and guess what the bios solved...stability issues with Nvidia video cards. I flashed the bios and now everything is running VERY smooth. Games work great and I have had no BSOD issues since then. The 9800GT requires a minimum of a 400 watt PSU compared to the GTX, which requires a min of 450 watts. So I will be putting the GTX in my rig instead.
In the end, both of you are right. I will need to upgrade the PSU in the future AND the ram was the main reason for the BSOD. As for right now though, everything is running smoothly so I'm happy.
Thanks for all of your help guys!I really do appreciate it!
Glad you got it sorted. FYI, wattage is good to have, but when talking about video cards, look at the current on the 12V rail, which is generally the limiting factor.
