설치는 되는데 시스템이 다운 되는 현상이 발생하는데요...

먼저 버전은 Oracle Enterprise Linux 4(X86_64)이고
하드웨어는

CPU AMD 애슬론64 X2 윈저 5200+
Mem 8Gb
Board GA-M61P-S3 (GeForce 6100-430 칩셋)
HDD 히타치 시리얼ATA II 500GB를 쓰고 있습니다.

설치는 대략 10번 이상은 해 보았는데...
가끔 디스크 용량이나 하드웨어에 이상이 있다면서 죽는적이 있긴하지만...
다시 시도해보고 하면 설치는 되긴 되는데...

문제는 다른 Application(Oracle)을 설치하면 설치도중이나
Unzip 같은 명령을 실행할시 아에 시스템이 멈춰버리는 경우가 발생하는데요...

구글링을 해봐도 답도 안나오고 해서...여쭤봅니다.
중간에 띡띡 멈춰버리는 현상을 어떻게 해야 할지요?

참고로 boot 로그 같이 올립니다.
