9800GTX+ Problems

So a couple of months ago, I upgraded from a 7900GT to a 9800GTX+ with the following system hardware:

The new card ran great for a couple of months but now I can't play games without a CTD.
I cleaned all my drivers and installed new ones. Still the same result. Can someone help me out with a solution?

It all ran beautifully until a week ago. I am completely miffed.
Constructive criticism with a possible solution would be of great help.
I would really like to get back to my FPSes and RPGs.

CTD: Crash To Desktop
Sorry about that. I've been searching for an answer on the intertubes for some time now and the acronyms commonly used sorta slipped in.

Virus scans also done multiple times in safe mode.
I use Norton 360.
I've also used CCleaner, and spybot. I'm clean.
Definitions were updated.

I've updated to latest nvidia, directx, sound drivers from a clean wipe taking out any regkeys. Also used driver sweeper after a restart just to make sure before installing the new drivers.

The problem I have is that it starts the game, I get some logos, I get a loading screen, but then it goes crazy. I get textures plastered all over my screen, like a block of cement, etc. The colors also go crazy. My pointer slows down and stops pretty much. At this point I usually get a windows crash and my system restarts, or sometimes I can alt-tab out to windows and crash the game via task manager.

Other times, if i alt tab out and then back to the game it shows me a visible menu and I can load a game and play for about an hour with great graphics before it crashes again.

I've checked the temp on my gfx card, its usually around 30-35C after a couple of hours of gaming.

Suggestion::Go to control panel/system/advanced/system recovery and tell system not to reboot upon system crash,,that way it will/might display the fault/reason for your snafu,,also I noticed that you are running ram of different speeds 800/6400 and 5400/667,,try putting the slowest first making that the systems ram speed or go with the fastest alone....????..

@ KatoPlato: Must get my eyes tested, +1 Dokk2.
Also download Speedfan: It can monitor your +12v line and see if it drops during gameplay and also check your CPU and hard drive temperatures.

hi

am new to this. you may have an bad G-card, try your old card if u still have it, to see if you get the same result. or try a new card. you can return the new card when you find the problem.
