My computer wasn't working so I installed Win 7 professional. At first it works well but recently I get bluescreen everyday. If I watch videoes online with microsoft office open it would easily become slow and turn blue screen. I used Avast! this morning before I left to see if it is because of virus, but it turned bluescreen....Here's the description: Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7601.2.1.0.256.48 Locale ID: 2052 Additional information about the problem: BCCode: 7a BCP1: C07EC2E0 BCP2: C0000185 BCP3: 65B758C0 BCP4: FD85C148 OS Version: 6_1_7601 Service Pack: 1_0 Product: 256_1 Files that help describe the problem: C:\Windows\Minidump\041612-20342-01.dmp C:\Users\Ruiqi\AppData\Local\Temp\WER-249117-0.sysdata.xml Read our privacy statement online: Windows 7 Privacy Statement - Microsoft Windows If the online privacy statement is not available, please read our privacy statement offline: C:\Windows\system32\en-US\erofflps.txt Thank you so much!!!!!!!
