Also, what PSU do you have?
Full system specs are as follows: Biostar McP6P v. 6.3, 4gb PNY 800Mhz RAM, AMD Athlon II x3 440 @ 3.3Ghz, OCZ 600w StealthXstream PSU, and an hd6850 @ 820/1100 core/mem.
I use a 17" LCD, Should I put my refresh rate to 75 (maximum)? Also, do you guys think that my hardware is damaged? If my hardware is not damaged then I really do not care too much, it just the scare that me computer is breaking.
