Hi, everyone. I've been getting BSODs ever since I installed a RAM stick which differed from the other in my Inspiron 1420. I had to install a new one since the other no longer worked. The two RAM sticks differ from each other as I don't believe they are the same brand. One is by PNY Electronics at 2048 megabytes with a bandwidth of 400MHz The other is by Hyundai Electronics at 1024 megabytes with a bandwidth of 333 MHz. They are both DDR2. I'm just wondering if this could be the cause of the BSODs I've been getting. The most recent BSODs are the IRQL_NOT_LESS_OR_EQUAL with the driver ntoskrnl.exe and the number 0x0000000a. I've heard that if you can identify the driver then there could be an option of disabling or uninstalling that driver to stop the BSODs. Thank you.
