Windows 10: Upgraded computer OS

I purchased a refurbished computer it had windows 10 but, I just got a notice to delete the old OS. I am lost of what to do if I delete the old OS will I be able to recover my files if I have a system problem?

:)

 

Video card or RAM need upgrading?

Memtest: no errors after 10 hrs.
I'm going to perform the Primetest, later on. Get back to you on that.
I'm going to take it step by step, guys. I need to find the problem with this current computer. I might have to upgrade some components, so that it is still runnable. As for the new one, yes....i will build on it later. I need to find something decent 'gaming experience', all suggestions appreciated. THanks.

 

Windows 10 Upgrade 1903 64 bit Sleep Wakes Up on Multiple Computers

Someone suggested I look at all the drivers list before and after the upgrade. I did, nothing found/changed in drivers.

What I did discover was that after the KB4503327 upgrade, if I put the computer to sleep mode (via power menu,) I discovered the computer wakes up after the minutes set in the "turn off screen".
So, if the screen shutoff were five minutes and I put the computer to sleep, it would wake up after that amount of time, then turn the screens off after another time period of five minutes.

At this point, I have set the screen turn-off to "never" and any other sleep mode to "never".
Then, when I put the computer to sleep, it stays asleep.

This issue was never seen until this OS upgrade was installed in the system.

My next step is to upgrade the video adapter (something from 2007) to a new and different model adapter to see if that corrects this issue, or not. For now, my work-around is to set "never" in "sleep mode".

 

Need some advice on computer problems.

Run HDtune (free version) on you hard drive. but most likely that the problem. You can also test your memory with Memtest86 as suggested above
