The next thing I would suggest...go to the Toshiba website and look up your system. Under support, take note of what options you might have and the way to employ them.
If nothing else, track down the instructions on the proper way to use the recovery CD you have on hand.
Your STOP error is a 7E, very unenlightening, it can be found at http://www.aumha.org/a/stop.htm
A system thread generated an exception which the error handler did not catch. There are numerous individual causes for this problem, including hardware incompatibility, a faulty device driver or system service, or some software issues. Check Event Viewer (EventVwr.msc) for additional information."
That only leaves just about everything that could impact a system, including malware.
