Change your power settings.

Put the Computer to sleep > Never.

So I'm reading between the lines here but I take it you have a laptop with a bad battery and you have to keep the charger constantly plugged in in order to use it? But now after detaching it while the laptop is running it doesn't boot to windows?

Does it show the normal posting or logo screen? Can you get to the F8 boot menu? If so try the safe mode options and 'last known good configuration'.

Anytime I see the black screen with blinking cursor I will press and hold the power button until it force shuts down, wait maybe 10 seconds or so and restart it. If there is nothing significantly wrong with the system or hardware, then it will start normally at this point. If it does not start normally, then you may have a problem but we need to determine if it is software or hardware related. First, try repeating above but tap the F8 key (as DaveInCaps recommends) and try the last known good configuration and/or Start Up Repair to see if Windows can be simply recovered one of these ways. Post back results and we will have other suggestions to try.

You have to be a little bit crazy to keep you from going insane.

Once in a blue moon this little trick comes up trumps:

Turn off computer and unplug from power. Remove main battery too if it is a laptop. Hold Power Off/On button down for at least 20 seconds to discharge motherboard. Re-assembler and try again.

Always pop back and let us know the outcome - thanks

Tried that . Left computer on for many hours and it had 3 messages. Windows ex has stopped working- restart. Then on task bar failed to connect to windows service . Could not connect. And the hour glass has been there for 36+ hours.. And third one says c:\windows\ system32\config\systemprofile\desktop is unavailBle.could be on hard drive or network. Check to make sure connected and try again. If still not located,info might be moved to different location.. I hit the close on the restart one and homepage comes on and task bar has start on left and connection has x on it.

"Left computer on for many hours and it had 3 messages" (errors presumably).
Download and install this to see what the temperatures are like after a few hours:

Let us have your computer make and model number please.

"shuts down when unplugged"
If this is a laptop and the power has to be present to keep it running then it is likely that the battery needs changing.

Always pop back and let us know the outcome - thanks

Yep, looks like Gateway NV55S14u is the make and model number. Thanks, it might be useful if none of the other suggestions work out.

Ok thank you. I'm going to pick up a new battery and try that. Would that make it not connected to network though?

Don't spend any money until we have proved it necessary.

Yeah, a new battery isn't going to fix the problem although a bad one might have caused it if it led to a shutdown when windows was running.

Suggest you also try 'last known good configuration' from the F8 boot menu.

Edit Your original posting indicated when you booted up you just got the blinking cursor. Are you now saying it's booting into windows but is all screwed up when it gets there?

Where this battery idea crept in was this:
"My gateway shuts down when unplugged"

A bit open to interpretation but I'd assumed this meant that the computer was running, then it was unplugged from power. It should therefore have continued on the battery. I accept that we've now moved on from that.
