i have an amd athlon 7750 2.7 dual core processor with a nvidia geforce 8400 gs graphics card. and 2g of ddr2 ram. im on a tight budget lol. i have rivatuner for tweaking but really need help with my settings. my global 3d settings are all over the place. eg. antialiasing, mip maps, texture clamp, texture filtering settings etc. after my son had been messing with things he shouldnt.. Games crash, run slow, look terrible and i really want to restore my computer back to how it was. i have no good restore points on my computer at the moment. Also some settings in control pannel-system and maintenance-performance information and tools-adjust visual effects have been messed with to. The computer was fine when it was sold to me it was overclocked perfectly and playing grand theft auto 4, call of duty 4, crysis etc really crisp with quality performance suprisingly. also i have no idea whether rivatuner overrides nvidia settings or not. any help will be much appreciated . maybe sum1 is familiar with my system.
