Nothing, Nada, Zero Zilch, The Big Donut!

This week, it was abnormally hot and many of my boxes crashed left and right. The weather has cooled down but one of my boxes continues to lock up. I've even underclocked it and it still won't run properly. It's only function is to sit around and crunch Genome plus serve babe pics.

I wonder if you can overheat and slightly damage a cpu? :confused: It ran perfectly up until the heatwave this week and now is FUBAR. All it does is boot up, run a bit and hard lock.

Looks like I'm indefinitely down one box until I figure it out. :mad:

Does it lock up on boot, after awhile, or what?

Before I underclocked it, it would lock soon after booting in Windows. After I underclocked it, it will run for some time and then hard lock later.

It's a 1.4 T-Bird currently underclocked to 1.33. There's (5) 80mm fans in the case with one blowing directly over the cpu. The HSF is a Volcano 7 with the fan modded to always spin at 5000rpm. Mobo is a KG7-Lite with 2 x 256mbs Crucial DDR.

You shouldn't need to underclock anything, it should run fine at the speed the cpu is meant to run. It looks like you have a good heatsink but as far as case cooling (which is actually more important) you should have an intake fan in the front of your case and an exhaust fan in the back so that you always have fresh cool air in your case to cool off your cpu (also make sure there is good airlow around the outside of your case). What are your current case & cpu temps running now? Try removing the case cover and have a house fan blow directly onto it that way you will definitely know if it's heat or not.:) :D

Air flow is pretty good, 2 80mm intakes in the front, 2 80mm exhaust on the back, Dual fan Enermax PS, and 1 80mm intake on the side of the case over the HSF.

It's been running for 2 month rock stable (1.4 T-Bird @ 1500 (10 x 150 fsb @ 1.95vc) but after Monday's heatwave, it refuses to run stable even at default (1.4 @ 10.5 x 133 fsb). I'll pop the hood open and if anything changes.

Dang goobee that's some rotton luck.
Don't feel bad dude, i have 4 casualties and it wasn't even hot. All i have now is a cemetary of rigs and i'm using would you believe a fossil ibm laptop with win95. Some piece of junk i picked up at a salvation army for 5 bucks ! If i can't crunch then i might as well root for the home team ya know.

Hope you get that other rig workin soon :D

Goobee, do like I did to keep the temps down on my t-bird 1.4... Drop the core voltage to 1.65.

Back on line guys, looks like the casualty was my hard drive. After it reaches a certain temp, it craps out. The Seagate diagnostic software returned an error code so it's going in under warranty return. :(

Just the same, I'm replacing the 80mm fan on the side of the case with a 120mm. That should help reduce case temps in the future.

Thanks for the help guys.
