My PC Runs Too Slow Again and can't view my yahoo mails

This happened last Saturday. Before we left for sightseeing, I opened first my pc and checked my emails to see important messages from my sister. It took around 20 minutes just to open my computer. I know this is an obsolete one but I still love to use it. I love to use this better as my netbook. I need some patience while waiting for my pc to open. Another sad thing that happened last Saturday, I can't view my yahoo mail again! I immediately switched to yahoo mail classic.... .and there I go I finally checked my mails.

This morning as I opened my inbox again, it won't allow me to view my yahoo mails. what's going on in here? or is it my computer or yahoo is having problem in viewing mails. What I did was switched again to the new yahoo mail version. Sometimes I am just scared when these things happened. I am asking sometimes, what if I can't read and open my mails when there are a lot of important messages there? I hope this won't happen. For now, my pc is doing good..I know it is already very old but I still love to use it...that's all for now guys..feel free to visit my other homes for more updates! Enjoy your day!
