| You can't go back to earlier restore points if they are not listed. Computers often slow down because many add-ons like RealPlayer, etc., often get set up to always load at startup and you have a lot of stuff hogging system memory when it's not necessary. There is a way to check on and change some of this. But first you need to run an anti-virus scan, and something else useful like the free program Malwarebytes, which will find stuff that even good anti-virus software misses. Do these things, then report back. And do tell us what those error messages relate to. |
