I have an older Pentium ll on whcih I have a lot of useful info and use as a secondary computer. Recently after about half hour the computer shuts down on me I have checked the power settings and there is nothing to indicate power save and I have it programmed not to shut down at all. I now get the following message: Attention on signal check input signal connection or follow power save mode has been enable. This makes no sense to me and I have to wait a couple of hours before I am able to get system on again when it works for a while and then crashes and I get above message. I checked for viruses but appears to be clean. PS How does one post continuing messages on the same threat as I would like to thank parties that respond.
