May be it is, But all I know there's some thing wrong with the gpu. And I say "glitch" because why else would it work fine a few min after the fact...or immediately after in my case, just powering it on a different way
If it had true broken solder connection, powering it on/off sure ass hell wouldn't have gotten me any ware.
Now wouldn't over heating come before power failure? solder melts at 200 to 840 °F, So lets go right in the middle at 300-450*F cause I know they wouldn't use the cheapest grade solder cause it's a bad conductor of electricity(and corrodes) And I'm almost positive they didn't use silver solder cause that's way to expensive. But back on topic, I know for a fact it never it got hot enough to melt the solder.....that's Hot!
The hottest it ever got was some were around 98 case temp right behind the chips, But that was with the cd drive running full bore playing halo3. (My computers drive gets ef'in hot two, what gives? but i digress)
