Well I understand how msi is on their warrantys and I am still under it, 2 year parts and labor, 3 years on parts.
I have RMA'ed a previous geforce 4 Ti 4600, it was the first model and it did not suffer from such problems. It ran smoothly and over clocked nicely. It had died and I am not sure whether it had been ESD'ed or if it had of been fan issues I had when I put on a GIANT II(worst investment I could have made) It over heated and I got lots of video artifacting, I finally returned it tho and went back to the older fan that cooled just fine. However it was awhile that my video card still ran very well till it had started giving me errors when booting up, anything in text displayed ok, anything with any sort of graphical movement or higher res would completely distort from it giving out. It eventually booted into windows with out much hassle, went solid for a week playing games etc, then next reboot that was it for the card.
I installed my radeon 9000 pro, rma'ed the geforce 4, then got it back from msi a little over a week ago.
I had found that it was giving me errors in these games I tried to play as it just freezes for seconds at a time, the rest of the time it works just fine.
As for my fan setup in my computer

That should give you an idea of how I have it, 6 case fans total, plus a 92MM fan on the zalman heat sink that still helps cool just about anything around it such as a ram and video card. Plus the side fan gives plenty of air to the video card.
Right now my computer is running at 37C for the CPU and 35C for the motherboards temp.
I dont suspect heat to be an issue here, even the top of the video card has a plate on the memory to help cool it and the HSF on the video card seems to be staying fairly cool.
So it could either be the card is deffective, or AGP port, but come to think of it, it could be as well that I might be low on power possibly. I have a 420w PSU.
However the radeon 9000 pro didn't have any problem, it ran ok and even in those two games, except it didn't run the games well because it wasn't fast enough.
So that leads me to believe the agp port might not be the problem here.

Athlon XP 2700+ non barton
2x512MB kingston hyperX pc3200 memory
Asus A7N8X Deluxe Rev 2.0
MSI Geforce 4 Ti 4800, (it reports as the 4800, but MSI's link calls it a 4600-8x)
Creative Audigy Platinum
Zalman CNPS3100-Plus(Heat sink fan)
Floppy Drive

Plextor 40x12x40a CD-R/RW
2xIBM 120GB drives
2x160GB Serial ATA drives in raid
TTGI 420W PSU
I know I need a new PSU, however I was going to upgrade it about the same time I get a new video card which will be soon, however I was going to wait till the NV40 line came out when I purchase one as I will be using too much power, but I could just be already.
I think I might go purchase a new PSU tommorow tho and check it out if it tests out ok in the other machine, I haven't had time to do that, but I will either tonight or tommorow.
I am wavering on the possibility that it is the power being an issue here as it is running on edge and plus this TTGI PSU might just not be putting out as much as it should since not all cheaper ones like this one do actually put out the max watts as it is specified to.
