Otestoval jsem nekolikrat RAM, vse v poradku(golmemory test, memtest86)
Nevim kde hledat chyby jestli v hardwaru nebo nedokonale WIN 7(ovladace,atd...)
Bios i ovladace jsou aktualni. Vsechny aktualizace stazene.

Sestava: ASUS p5e3, intel E8400, KINGMAX DDR3 1600mhz, FORTRON 700w, SEAGATE 1TB, NV 9800gt

Predem dekuji za rady a prispevky.
