Odds are without some serious hashing power you're not helping. You have the potential to, of course, but it isn't likely.
Yeah...I took calculus, too.
The generation numbers I was seeing were probably responsible for more coal burning than it was worth. Now I am actually making a bit of progress.
On topic, though, a friend of mine had a similar problem. His computer kept crashing whenever he would check the "Generate Coins" option in the client. We had him uncheck that and get up to speed with the poclbm miner...he has a 4850 and was pulling down 60-65 mhash/sec once he was configured correctly...but his GPU still climbed up over 110 degrees and would still crash his computer.
Turns out he may need a new mobo after all of that...it doesn't run the fans right, and even with the GPU fan running at 100%, I doubt that would be enough to keep everything cool. That much heat is just not good for mining...or anything else.
We used to run a lot of @Home stuff, and I'm wondering if it's a similar load on the system...never had problems like that with it.
