請問SP2004 燒機錯誤訊息

小弟的配備是
E6300 沒超頻
EP31-DS3L
海盜DDR2 800 1G*2
WD 250G
保銳 400W
ASUS 7300GT

在燒機的時候出現了這樣的訊息

Test 2, 4000 Lucas-Lehmer iterations of M19922943 using 1024K FFT length.
FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.
Torture Test ran 2 minutes 51 seconds - 1 errors, 0 warnings.

燒機溫度大約55度左右

請問是哪個硬體有問題呢？謝謝！
