Intel Core 2 Duo E7400 2.8g
Asus P5Q
Kingston 2x1gb ddr2 pc800
Palit HD 4850
1 hitachi 400gb sata hdd
1 western digital 160gb sata hdd
535w enermax fmaII
an old 500w logic avr

Check for the obvious: Dust, overheating, etc......

Are you at stock clocks?

Underclock your RAM and see if that helps.


You may be on a one way train to warranty town........

no overheating

no overclocking either

i havent underclocked the ram...i switched back to my old x850xt for the meantime. i'll try your suggestion next week but thanks!
