Hi. I've been having an issue with my computer where it has slowed down a bit and it's very noticeable. It is slower to open certain files or pages but not all. Also, when i place the cursor over a link or menu line and click on it, it does nothing and I have to continue to click until it catches on. Again, it does not do this all the time but maybe more than 50 % of the time. Last, when i place the cursor on the back page arrow it usually takes me to the page previous to the last one. That happens when i place the cursor over the arrow and click on it but if i place the cursor over said arrow and wait two seconds it takes me to the previous page 100% of the time. This shouldn't be happening as I have a fairly fast system, i5 6600 cpu, 16gb of memory, Asus Trix 9800Ti video card, and a new Samsung 970 Plus SSD. To top it all, I don't have a lot of files or photos saved in my system so it should be a lot faster than it is right now. Do i have a corrupted OS? Any other ideas? Thank you for your time.
