I see the software approach didn't pay off.
I also don't see the make/model/CPU/details so I'll offer this.
1. Remove the case cover. Leave it off for now till it's fixed.
2. Remove the dust bunnies.
3. See if the CPU heatsink is clean.
4. All fans are spinning well?
5. The motherboard (and other) CAPACITORS must not have domed tops or leaking fluids. Pictures? Article about this issue? -> http://www.pcstats.com/articleview.cfm?articleID=195
