OS: Vista Ultimate 32bit sfc /scannow -> all ok!! chkdsk -> all ok!! Also I don't have any virus, it's a clean system. So sometimes (3 out of 10), not all of the times, when I start my pc WerFault.exe terminates proccess spoolsv.exe, which lies in the system32 folder and is not corrupted and malware free. This issue occured only recently, after having set some programs in auto-startup, so I personally believe it has sth to do with ram or cpu usage at start-up point. I even disabled DEP, cause I thought it was the fault. Would anyone know anything about it or give an opinion? Feel free! Thank u!
