As for your issues it is very difficult to know if a Repair Install will fix
them. It is always prudent to back up essential data on a regular basis and
it is very important to ensure critical data is backed up before attempting
any type of repair. Typically a Repair Install will not affect your data or
installed programs but you should be aware that on occasion a repair install
doesn't go well either because it is done incorrectly, the system is not
properly prepared or there is hardware damage..
Before resorting to a Repair Install you may wish to try a few other things
if you haven't already.
First do a thorough spyware and virus scan cleaning out what is found.
Running your anti-spyware software from Safe Mode is a good idea.
Second ensure you have the latest drivers for your video card.
Running diagnostic software for memory and hard drive can be a good idea.
You can typically get hardware diagnostic software from the hardware
manufacturer's site but be careful with it and ensure you have a backup of
your important data first. You may wish to do a software check of the system
memory too. Bad memory can be the source of a lot of frustration. Here is a
tool you can use to create a bootable floppy or CD to run a check on your
RAM
