wonder if it's time to check capacitors again ... look for convex tops when the surface should be flat and level on the electrolytic capacitors ( minature soda can looking things )

I've been dealing with the exact same issue this week. An OP755 randomly rebooting. I've swapped the power supply and plugged into a UPS with no joy. Just before I left yesterday, I threw the hard drive into an identical machine because I started to suspect the CPU.

We change a setting of the Intel MT NIC, motherboard and reinstall OS (RedHat 5.x). We suspect that it could be the CPU that is rebooting the machine before it could get burnt or maybe a failing power supply. Do you guys know of any live CD (Windows or linux based) to run a stress test on the CPU? (it's a quad core) Thanks, Miguel ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ -- Organization and good planning are just crutches for people that can't handle stress and caffeine. - unknown ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
