Hello and welcome herschelle now if you can get safe mode at all I would run these at very least

It does however sound very much like the machine has malware on it so one thing you could do if you have access to another machine is to use this
http://support.kaspersky.com/4162 < this will run from power up and scan for malware without the need for Windows to be running - that is because it is a bootable program in it's own right. You can make a disk or USB stick to boot from - you will of course need to set the BIOS boot sequence to that particular device disk or stick.
