I have had to reformat 4 times in the past week. Running windows 7 on my AAO AOA150 mini laptop. I have run memtest86+ (finally found a easy to use usb tut, that worked) and passed 5 tests over night, no errors. Yes it is new ram. This install ive used sfc /scannow, nothing wrong. checked the disk, no errors. I debugged the 2 new bsods from the last day and they were caused by: System, and csrss.exe. I am new here, hi.
