Im not sure exactly what it is. Randomly my computer screen will just go black, then the sound turns off. But the computer is still on. It never gives me a error report for the problem either.
How do you get the computer back to a working state when this happens? Could it be you have your screen saver set to "Blank" or maybe the computer is set to go to sleep after a specified time interval? A bit more information on your setup such as make and model of the computer, what video card do you have, what video driver is installed are you having any other problems and etc. would be helpful. It could be anything from a simple setting to a hardware problems to heat issues. If it's a laptop it might be your power supply.
You really need to supply a wee bit more information in addition to it goes black and I have to shut it down.

Is this by chance a new computer still under warranty or is it a custom build? How robust is your power supply? Have you recently made any changes just before the problem started? How about air flow through your box? I've seen computers shut down because of CPU overheating. Although those were usually AMD processors.
"How robust" = how strong. In other words is it up to the job? The specs on the newegg site say "Standard ATX PS2 / EPS 12V (optional)" but I didn't see anything about wattage, number of rails and etc.. My question is basically asking is its power output sufficient for the job you've given it. I have no idea if it is or not, but lack of power can cause your problem. I've never had especially good luck with an included PSU. Right or wrong, my feeling is those included with the case are not really decent quality. But, obviously, that's just my opinion. By asking about changes, I was trying to ascertain if your problem started after you made some sort of significant system change. If that was the case, undo the change and see if that fixes the problem. If you've made no changes then that can be eliminated as a possible cause. If you feel you need extra cooling, try running the system with the case open and a box or floor fan flooding the case interior with air. If that has no effect, you can likely eliminate excessive heat as an issue. At this point it's all a guessing games and you need to start eliminating possibilities one by one.
That link is just the case. I have a aftermarket power supply. Either 600W or 750W. I forget. Ive had this problem for quite some time. It comes and goes.
My final guess would be a bad install. It's your computer, of course, and you're free to do as you please. If it were me, I'd backup all my data, wipe the drive and reinstall Windows.
That is no excuse there are direct links on this forum to download windows 7. If this is a genuine copy of windows make sure you backup your windows key.
Before you reinstall Windows, check the 4-pin CPU power connector(see below), exactly the same problem happened to me. Also, schedule a RAM test, or use a linux distro to check for bad RAM.
This is the stuff from the past 2 weeks thats in the event viewer. -The shadow copies of volume C: were aborted because the shadow copy storage could not grow due to a user imposed limit. -A timeout was reached (30000 milliseconds) while waiting for the AMD External Events Utility service to connect. -The AMD External Events Utility service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion. -The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
I think it's something to do with a power feed problem somewhere but I don't know where. I guess I'd first try another power supply.
The first thing i would test would be graphics card and monitor.. Do you have a spare graphics card, or can borrow one from someone.. You can also try using another monitor, or trying your monitor on another PC.. Usually this kind of faulty is cause by faulty graphics card, over heating, or not enough power getting to the graphics card - weather from under powered power supply or faulty power supply or cabling. But the monitor could be faulty, and the reboot of pc is causing reset, which brings it to life again.. I have seen this once with an LCD.. would go blank from power saver coming on when no activity on PC, then it couldnt get out of power saving mode until PC was rebooted or monitor was disconnected from PC and reconnected again..
