Hello I read the previous topic about computer crashes. but I think mine its different because it acts weird. for example last night I start experiencing this effects, like for example Im working and suddenly freezes, or sometimes it takes an hour to freze or maybe 10 minutes or even 1 so i dont know when my next freze will be. but the fact is that when I reboot my computer the monitor does not turn on so I have to unpluggled the cable and wait like 20 minutes to start over again, sometimes it does not work it taskes a full day to answer, so this is driving my crazy, even when I try the Mcafee virtual technical suddenly stops or even the Window fixer program that is included stops so what is the problem, I checked the Bios and it seems normal so I dont know what to do. Sorry for the bad writting but I dont know when the next freeze will be.
