The system is sort of unstable and it crashes frequently. By crash i mean the screen suddenly said it's "out of range", while doing normal task or sometimes it just stops responding(even idleing). P4 630, 1gb supertalent ddr2 n 256mb ddr2(meant to wrk in dual channel but didn't wrk out), 160gb maxtor diamondplus9/8mb, Asus x600xt/128Mb, ECS PF4 MB, 550W PSU, and nothing is overclocked. In addition to that, I could change everything else in the BIOS except it won't let me enable the HDD SMART function. Enter the BIOS again it's still disabled, even i enabled it and saved it. The system also "magically" overclocked itself to 3.2GHz after i left it on for a day. Any suggestion would be greatly appreciated. Thanks.
