Joe,
Are you saying the PC was brand new 8 months ago? Do you have any kind of warranty? We buy all our desktop PCs from Dell. They have a 1-year warranty included, plus we always buy at least 2 years additional extended warranty. The extended warranty really makes sense in cases like this.
Intermittent STOP errors are really the most difficult and most time-consuming problems to troubleshoot. If you have not done any software upgrades or additions, or added any hardware, my feeling is it is probably either a bad RAM module, or a RAM module which needs to be re-seated in its socket. (but there are certainly other suspects)
A shop is going to charge you hourly for this kind of problem, and there is no guarantee of success. Most people with the skill and patience for this kind of troubleshooting, are not working in a PC repair shop like the Service desk of CompUSA.
Since you are getting a different STOP error each time, to me that means that the trigger is unrelated to what you are doing with the PC. It could very well be heat-related. Does the STOP error seem to happen when the PC has been powered on for a long time?
