I've uninstalled Catalyst 4.7, to install Cat 4.8. I usually run DriverCleaner in safe mode to delete the remaining files after uninstallation.

Today, i've got a serious error that didn-t let me enter on safe mode. if i start windows normally it goes without any problem but on Safe mode it shows me a Blue Screen with the following code:

IRQL_NOT_LESS_OR_EQUAL

the last time i've got this error was my modem driver (USB) but now i don't have anything working on USB except de Bluetooth Key, but i dont think thats what it's causing this problem.

I Recently acquired an DVD-RW, but i still dont think that is causing. Tried on Support of Microsoft and nothing could help me. does anyone knows what kind of problem/conflit this is ?

I apreciate your help

this error generally occurs when there is presence of faulty hardware present in the system . In short it is trying to access that part(portion) of memory for which is not granted permission

Stop 0x0000000A or IRQL_NOT_LESS_OR_EQUAL

to reach the depth 1) Reboot keep F8 key pressed you will be presented with the menu . Select Last know good configuration (The system will start up normally)

now right click my computer > manage this brings Computer manangement

select even viewer and the double click on system to find the event that caused probs

but it's strange... it only happens on safe mode. should this error affect normal mode too ?

try to uninstall InCD if u have installed it.

if yes, this will probably solve your pb (i had the same).
