3. Adobe flash plugin crashes a lot and I finally uninstalled and reinstalled a new one, but every once in a while it says that again.
4. "Firefox can't find server at us.mg6.mail.yahoo.com"
9. Every so often, not a lot, but XoftspySE will pop up and says to reinstall because of missing components. I thought we had gotten rid of that a long time ago. This doesn't affect anything, I just skip it and go on.
3. This is a hard one for me. You've uninstalled it and replaced it with a new version, and you've uninstalled Firefox with the most recent version. I would think the problem would be with some of your add-ons, but I could be wrong. Remember how to disable add-ons? Try disabling all add-ons except for adobe flash, think it is called shockwave flash object. Let me know if you get any further crashes, after this. I know this can be inconvenient with add-ons disabled, but this way we can know if add-ons are indeed causing the problems
4. This may be a Yahoo issue, and their servers may be down. I honestly have no idea. When I said I'll help you with
4, I meant
5. sorry for the mix up on my part.
5. This could be anything from hardware to software problems. I will make a seperate post to help you with this issue.
9. XoftspySE is an antivirus program, and you are only supposed to have 1 of those installed at a time (You also have Microsoft Security Essentials if I'm not mistaken). This may also be a reason your computer is freezing. You also have Revo uninstaller installed, yes? To remove XoftspySE, use Revo uninstaller. If you need to, download it here:
Download Revo Uninstaller Freeware - Free and Full Download - Uninstall software, remove programs, solve uninstall problems
Before we do this,
create a restore point. Here are the images so you can follow along visually:
a. How to find Revo uninstaller by typing it into the start menu search:
b. Type "Xoft" or "spy" into that search bar (in the picture, it has a red box around it) and find the program XoftspySE. Click the antivirus program called XoftspySE and at the top, click uninstall. I've installed Timbury to show you how to uninstall a program.
c. There will be some nexts, yeses, and finishes that you will need to click

d. When this page pops up,
only select the items in the list at the bottom of the files, don't select any of those files. Only the weird registry looking bolded icon should be checked, as the picture says, but select all of the bold icons to delete them
Let me know how this goes and if you need more help.
