Hi, I have an HP pavillion laptop that's about 18 months old. It originally came with Vista, but I installed windows 7 nearly a year ago. I hadn't really had any problems up until January, when I started getting blue screen errors. The latest one came up with this: Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7600.2.0.0.256.48 Locale ID: 4105 Additional information about the problem: BCCode: 50 BCP1: FFFFF100C275EAC8 BCP2: 0000000000000000 BCP3: FFFFF96000152E5F BCP4: 0000000000000007 OS Version: 6_1_7600 Service Pack: 0_0 Product: 256_1 Files that help describe the problem: C:\Windows\Minidump\032211-22526-01.dmp C:\Users\Brie\AppData\Local\Temp\WER-58921-0.sysdata.xml Read our privacy statement online: http://go.microsoft.com/fwlink/?linkid=104288&clcid=0x0409 If the online privacy statement is not available, please read our privacy statement offline: C:\Windows\system32\en-US\erofflps.txt I'm not really good with computers, so I have no idea what to do to fix it.

Bug CHeck COde 0x50: The PAGE_FAULT_IN_NONPAGED_AREA bug check has a value of 0x00000050. This indicates that invalid system memory has been referenced.

Also, as you have multiple BSOD causes that I am unable to analyze all of them, I recommand to you use memtest86+ to check if all is okay with your RAM or not. If it detects a faulty one then replace it. This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
