BSOD on startup

Riri · 17 Apr 2011

Hello all,
I have a problem with a Toshiba satellite L655 (windows 7 home premium 64 bit). After installing an update, it started crashing randomly until it reached a point where it crashes immediately after log in. The only way i can log in is by using a memory stick as a backup ( and it only works in safe mode). I apologize for not being able to perform a system health report, but i got the Windows_NT6_BSOD_jcgriff2 zip.
Please show me how to fix this. Thanks in advance :)

These were both caused by your iastor.sys driver (your storage driver). A simple re-install in safe mode should do the trick

thanks! I've deleted the Driver all together after several attempts of reinstalling it. Now the laptop is working with an older one ( with no iastor.sys ) it worked for now... but i guess i need to find a new driver soon.
thank you so much for pointing out the problem ^^
