Okay. My laptop is new, just 1 week. It's a Lenovo ideapad z470. I get random IRQL_NOT_LESS_OR_EQUAL BSODs. I've already had 5 of them. They mostly occur in 2 day intervals but today I had 2. Here: Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7601.2.1.0.768.3 Locale ID: 13321 Additional information about the problem: BCCode: d1 BCP1: 0000000000000028 BCP2: 0000000000000002 BCP3: 0000000000000000 BCP4: FFFFF8800171AB2D OS Version: 6_1_7601 Service Pack: 1_0 Product: 768_1 I have attached the minidump files and when I viewed them with BlueScreenView and it said that it was caused by NETIO.sys and ntoskrnl.exe but I don't know what to do next. Laptop Specs: OS - Win7 Home premium 64bit Intel Core i5-2430M Processor @ 2.4GhZ (2nd Generation) 2GB DDR3 RAM and also, i had 2gb additional RAM installed when I bought the Laptop. Help. Thanks.
