Toshiba A 215 Frequent Blue Screen

I have a Toshiba a215

PREVIOUS:windows vista premium x86(32bit) on previous hardrive

PRESENT:windows 7 x86(32bit) OEM now on hardrive

The time of having the laptop is 2 years 3 months and i changed the hardrive once since december 2010

The age of the OS now on it is 4 months

I have try most troubleshooting tools like windbg,bluescreen view, whocashed memory testing taking apart and cleaning however i am not able to identify the probelm or the cause on thing it is related to hardware because the file causing the problem is ntoskrnl.exe and the stop error is 0x124

sorry it look like i registered in the vista forum instead of the windows7 forum

I am assuming that you have read this already if not please do..

Based upon the older BSODs,Most likely caused by your anti virus. Go to the webpage and use the uninstall tool. Replace with microsoft security essentials and scan one a week with malwarebytes.
