I have to turn my computer on and off at least a half dozen times before I can get to my desktop. Usually about 3 times before I get the screen telling me that windows was shut down abnormally and giving me several other starting options. At this point, I choose safe mode and sometimes it frreezes midway through loading the drivers and always freezes after loading all the drivers.
With every cycle, the process goes just a little farther with safe mode finally loading or sometimes, I try to let windows start normally with that working as well.
No matter what, whenever I get to a point where I can restart the computer, it's fine from there on. Never any problem on restart. Might I be experiencing some sort of hardware failure?
