Computer Is Quircky

[Ron]

My computer is acting strange.
When I am not at my computer it goes into power saving mode.
I had an incident that made me thought it was more than that.

I noticed it was in power saving mode, so to wake it up I moved the mouse & tried touching the key.
A message came up on my monitor that said no signal.

I tried rebooting it. Upon rebooting, still nothing, upon the second reboot it finally worked.

Any ideas as to why? I recently transfered ten gigs of files over.

One important reason is my warranty is due to run out next weekend.

Any help is appreciated.
