When I had my 9800GTX installed everything was working pretty well and I rarely if ever crashed but now that I upgraded from the P09 to P10 bios and bought a GTX 480 GPU I get lots of crashes and BSODs while gaming. I posted a topic in the graphics cards section but wanted to post here to make sure all of my bios settings are correct. I gave away that old 9800GTX so I can't test a different card at the moment.

Okay I reset my bios then removed the battery for 15 minutes and then reset my cmos jumper. While I had my case opened I read the side of my ram and it says 1.7v so I fixed that in the settings this time with the appropriate 9-9-9-24 timings. Everything else is as I had it before. I started playing Aion again and after about 25 minutes I got a BSOD involving nvlddmkm.sys like I do a lot. Other times it will just freeze in other games like L4D2, Just Cause 2, and so on. What's the next step? If needed I can do a clean Windows 7 install (I was about to do that before I made this post). The PC is rock solid and can stay on for days at a time while downloading or just playing music but when I start gaming I get lots of issues.
 
Edit: Also if you'd like to rule out the RAM or GPU I have a set of OCZ RAM I used to use before I replaced it with Patriot RAM. I can also take the GPU out of my other PC and place it in this system if you want to narrow down the problem. It's a lot of work though.

I made all of those changes and windows is 100% stable when I'm just surfing the net, watching videos, or listening to music but when I started playing Just Cause 2 it crashed after 10 minutes of gameplay. Anything else I can try?

I uninstalled and deleted my DisplayDriver folder then reinstalled my drivers again. I'm stilll using the latest graphic drivers.

Now that your sysytem is up and running you need to go back to your GPU thread and check out some PSU issues.

A few things:
1.  You say that the system "crashes" when you game...exactly what happens?  What is the error code, etc.?
2.  It would help if you listed all of your hardware....what brand/model PSU are you using?
3.  What do your temps look like when you game?  What temp monitoring software are you using?
4.  What CPU cooler are you using?
5.  What type of case are you using, and does it have good airflow? (you temps will answer that question)

1. In Aion I get a BSOD related to nvlddmkm.sys (if I remember correctly) and every other game freezes w/o a BSOD. They just freeze and the audio loops and nothing on the PC responds.
2. CUQ 1200-B Coolmax 1200 watt
3. My temps are great. I monitor my GPU temps through my G15 keyboard using EVGA Precision. They range from 40-ish idle and up to 65-70-ish under load with my fan at 70%. I've tested my CPU before while gaming and it was alright at the time. I haven't monitored it recently though.

Did you use a driver cleaning program to remove your vga driver's?That can also affect the stability and cause crashing.Once you remove and re-install said driver's I would run Intel burn test for twenty passe's.I have a feeling that some voltage's still need to come up alittle.

I reinstalled windows and installed the graphic drivers with the hdaudio and 3d executables removed before installation but it still crashed after that. I then lowered the settings of my card to that of a normal GTX 480 instead of the superclocked settings and now I haven't crashed yet. After I test my PSU with a multimeter and it looks okay I may send the card back for a replacement if I can't get it to run at the superclocked settings. Any suggestions?
