I have an Acer Aspire 5517 Laptop.

Operating System is Window 7 X 64 Home Premium.

AMD Athlon TF-20 1.6 GHz Processor

2 GB RAM_ Physical Memory

220 GB Hard Drive

I leave my computer on during the day, and leave it occasionally  for short periods of time..Lately, when I come back to it, the screen will be black..It is black because the computer turns itself off, for no reason that I can find out. When I turn it back on I get a caption that says the "user (name)has been locked out." Below that is a caption that I can click on that reads "switch user." If I  click that caption, it says "user logged on." Which is the user that was just locked out! I click on that and my desktop comes up like nothing happened....

So far, to try and correct it, I have flashed the BIOS, because it needed updating. I thought  this might help, but it  has not corrected the problem. I  have also done all of the standard things like defrag., cutting down on desktop icons, fewer starting programs, etc.

Does anyone have any ideas that I can try? Any help appreciated!

My problem  has changed. So, I need to modify it a bit... Don't know  if it is for better or worse..... but now when my screen goes black, the computer is still on. It no longer shuts down... The HDD light  is on and blinking. I can turn the computer off, by holding the power button down for a few seconds. I leave it off for about 10 or 15 seconds and then turn it back  on...The computer  boots, but I, of course,  get the message that  it  shut down improperly and It asks me how I  want to  start it, and gives me choices, among  which are start in safe mode, start with networking, or start normal..I choose "start normally" and it boots  up with no problem and is  back to normal..The black screen is showing up more frequently, it seems, as time goes by...

Anyone  have any suggestions..??
