You have a System Repair CD, not an Installation DVD.
It sounds like it repaired the problem until you installed Updates at reboot, correct? You should have a System Restore point any time you install Updates, so if there is a problem with the Updates installing, System Restore and install the Updates one-by-one until you find the one which is causing the problem, then open a Support Case on WIndows UPdates website to resolve that Update via email.
If this is not the full problem, or doesn't solve it, I would find or borrow a Win7 installation DVD to clean reinstall the OS after backing up files externally and wiping the HD of all code: SSD - HDD Optimize for Windows Reinstallation. I have found this is always a superior install on an eMachine which never integrates factory preinstalled bloatware or utilities well.
We are not allowed to link to the Win7 installation ISO here but you can search for it on a safe site like Digital Life which hosts official downloads. Follow these steps to get a perfect reinstall: Reinstalling Windows 7
