trally :
RAM test run with no problems detected. Malwarebytes ran full scan with no threats detected. Ran SEP live update and performed full scan with not threats detected. Previously two system restores were done, not a full reinstall. Any other thoughts/options prior to a reinstall? Would a reinstall impact my Outlook files in any way? I've lost emails due to the system restore (advice appreciated if there is a way to back those up). Thank you!
Outlook:
You should EXPORT your e-mails to a separate drive or device, then IMPORT them after reinstalling Windows. The format you would choose is called "PST". You should end up with a single file (you can name it) called "outlook.pst" or whatever.
Reinstall Windows:
Take your time to plan this (backup date, write down programs to reinstall, make sure you have the install disc etc.)
*Make sure after installing Windows to download and run the relevant DRIVERS, especially the main CHIPSET driver from the motherboard support site.
Backup Windows:
I use Acronis True Image 2013. There is a free version of that. There's also Windows 7 Backup software as well. My advice is to make a BACKUP of your C (Windows) drive once it's been reinstalled and the programs/data etc sorted out. You can then RESTORE things far easier if you need to.
ALWAYS keep the first backup you make after sorting out your Windows installation. Later backups may have malware creep in that you aren't aware of.
*I use Acronis True Image 2013, set to AUTO backup my main Windows drive to a separate hard drive. Backups are WEEKLY. They are incremental. I have it set to DELETE older backups. Again, keep the FIRST one.
