Used laptop that I received for christmas yesterday has now shut down three times with blue screen. After the first time, I installed Avast! and it found two malware files and two corrupted files in the boot scan. It has shut down twice since then, once in the middle of the scan. I am not sure what you will need to know, but here is what the error found message reads: Problem signature: Problem Event Name: BlueScreen OS Version: 6.0.6002.2.2.0.768.3 Locale ID: 1033 Additional information about the problem: BCCode: 50 BCP1: FFFFDA800729B4B0 BCP2: 0000000000000001 BCP3: FFFFF80006C6E9EF BCP4: 0000000000000007 OS Version: 6_0_6002 Service Pack: 2_0 Product: 768_1 Files that help describe the problem: C:\Windows\Minidump\Mini122611-02.dmp C:\Users\Owner\AppData\Local\Temp\WER-42494-0.sysdata.xml C:\Users\Owner\AppData\Local\Temp\WER627.tmp.version.txt If anyone can help, I would be beyond grateful. The laptop is amazing and runs so smoothly, blue screen aside. I would hate for my christmas present to be a dud.
