最近朋友電腦一直當機

cpu:630
RAM:海盜牌1G 512x2
MB:GA-915 Duo
VGA:6200TC
HD:WD 200G SATA
power:佶偉350W


以上是一月六日左右時裝的電腦

上網瀏覽網頁或下載東西
瞬間就當機了
藍色畫面
之前是一直重開機
我幫他安裝了sp2的xp後
就開始只變成藍畫面了

訊息是以下


A problem has detected and windows has been shut down to prevent damage to you computer
DRIVER_IRQL_NOT_LESS_OR_EQUAL
If this is the first time you’ve seen this stop error screen restart your computer. If this screen appears again. follow these steps.
Check to make sure any new hardware or software is properly installed. If this is a new installation. Ask your hardware or software manufacturer for any windows updates you might need.
If problems contuinue, disable or remove any newly installed hardware software. Disable BIOS memory options such as caching or shadowing. If you need to use saft mode to remove or disable components. Restart you computer. Press F8 to select Advanced startup options,and then select saft mode



希望大大能幫忙
是哪邊出了問題嗎?


暫時懷疑是記憶體
所以今天要去換~
如果還是一樣
決定把6200TC換掉
這樣對嗎?
