Voiçi ce que j'ai lu sur un site d'O/C anglophone:
1.Create a RAR-archive 3 or more times as big as your amount of RAM. Create it in a non-overclocked system to make sure there are no errors. Then write a batch-file:
@echo off
: cont
rar t pack.rar
if errorlevel 1 goto exit
if errorlevel 0 goto cont
: exit
Put your archive (here - "pack.rar" ), this batch-file and rar.exe
into the same folder. This batch runs continuous testing and if CRC fails due to CPU, RAM or IDE error - it stops. It can show your problems very quickly - more often it is an L2 cache error due to overheating or low voltage. It can be runovernight simultaneously with a deep virus search or left to work inthe background with your office applications or games.
Donc si qqun saurait ce que c'est qu'un "Batch File" il serait très sympa de m'aider,merci
