Windows 8.1 - restore point

I cannot set up restore point! It said: "It doesn't have enough disc space."
Even I have slider moved to maximum disc space (configured), somehow it doesn't recognize that and I still have the same message! Please, help....I tried everywhere, but people helping me out with suggestions I already know! Do you have something new!? Thank you in advance!

Everybody said go there and there and increase memory size, set up restore point etc.....I KNOW WHAT TO DO, BUT I CANNOT................

hello coockie ,welcome to eight forums ,how could we add something new when you didn't tell us what you tried .
if the drive space is full moving the slider isn't going to help , you need to check to see that you harddive is not full ,

Hello caperjack, thank you for your response. Well, to answer this matter: I have enough drive space. Only I didn't say, I changed my original hard drive 750 GB with SSDI 500GB, but I don't think it's important...I have about 375 GB of free space....

follow this tutorial ,if it doesn't fix it ,then you have other issue ,

Thanks for suggestions, but it didn't work! New clue ! I discovered in log files that some sound software site deleted files connected to processes.....I don't know why or how, but it happened. I am Norton user..

I am not Norton user ! not that that has anything to do with your issue ,perhaps you have infection, did you try malware scan of the computer , iam malwarebytes user though and will suggest a scan of there free version .
