Random Crash, Freeze, Black Screen or BSOD shortly after startup.
This is a strange problem my desktop has had for a fairly long time. Usually, my computer will work fine, start up with no problems for several days in a row. And then..for reasons I don't know, it sometimes will start crashing. Usually the screen goes completely black and the computer completely non-responsive, and it must be hard reset to get any response at all out of it. A few times I've actually seen a brief BSOD, but too brief to actually read it and see what is happening. Sometimes the screen will just freeze where it is, with the last bit of audio that was playing repeating nonstop. The strangest thing about these crashes is they only happen a little bit after or during startup; if the computer is fine for 30 minutes, I know it'll be fine until the next time it's turned off. It has on a few occasions come up with a screen telling me that the CMOS is corrupted. I've had startup repair run, and tried some kind of hard drive diagnostic tool; the startup repair couldn't find a problem, and the tool said the hard drive was good. I've seen it crash this way in the middle of the bios boot, during login, in safe mode; pretty much any time during the first half-hour to hour of the computer being on. But never afterward.
I ran the diagnostic tool; the results are attached to this post. Any help at all would be appreciated.
(In case it has any effect on anything, my computer used to be a Vista and a complimentary upgrade was used to make it windows 7.)
