Ok here is the story.
Im a online gamer long time fan of any online rpg for the longest time i have been scraping by on the bare minimum of gaming hardware. I recently decided to play Everquest2 and its minimum reqs were a bit higher than what i had so i decided to upgrade, here is the problem. After swapping out my mmx 440 for a nvidia 5700 128 ddr card Apollo brand i was able to run everquest with no signifigant performance issues but one very annoying problem. Ranging from every 15 minutes all the way up to 2 hours i have random freezes. The comp freezes and nothing will end the freeze aside from a restart. After consulting a few forums i thought it might be a power supply problem. I upgraded to a 500w enermax noisetaker, no change game still freezes.

Next thing to check is cooling, despite running a temperature monitor and finding all temps in spec i added a 3rd cooling fan to my case on the side to push air directly onto motherboard and vcard, there are 2 other fans an intake and exhaust. with the added cooling no change still freezes.

A friend mentioned a possible memory leak so i purchased a new gig of kingston ram and although game runs smoother and load times are less the freezes still continue. All drivers and bios are updated with most current and for vcard drivers i tried the stock nvidia and the performance omega drivers with no change.

The motherboard is ecs k7vta3 with an athlon processor 1150mhz im not sure what other system specs i can give to help troubleshoot this problem, but id be glad to supply any info i can if someone would like to help me with this problem. At moment i have another vcard on order to test if somehow it is the problem since i needed another vcard for my other machine.

I am beyond desperate for a solution to this problem. this is my first post so if i missed any rules of posting all apologies.
