Neeed help with compute errors

Well why didn't you just say so? Here's what you do...

Grab a small pack of assorted transistors from Radio Shack for under $5. Take a few of them and hook them up to a 12 volt battery from a car or motorcycle. Disconnect the battery from the vehicle first so as not to damage the electronics in the vehicle. You can hook up transistors without resistors only so many ways and most ways will cause them to explode and stink. Wear gloves and safety glasses for protection from the heat and flying bits. Blow the transistors in the computer room so the smoke lingers a little. Do it just before she comes home. Make sure you keep 1 good one to show her how they look before they fry.

Now shutdown the computer, open the case, disconnect the power supply from the drives and motherboard. Toss the blown up transistors onto the floor of the case. Turn off the breaker that feeds that room. When she comes home you turn the computer on but of course it won't boot. Then discover the "tripped" breaker and give her the first "Uh oh, this doesn't look good." Now try powering up the computer again. Now a tear should trickle down your cheek as you moan "All I ever wanted to do was help mankind through research." Then open the case and "discover" the transistors that "blew right off the mother board". Man, it must have been one huge power spike!!! Now your bottom lip should quiver as you begin to sob and thank god she wasn't touching the computer when the spike hit else you be all alone and unable to carry on, there could never be another one like her.

A month or 2 after you have the replacement machine bought and paid for, one of your cruncher buddys at Einstein tells you how to fix the old machine. Well, now that you have 2 machines you of course need a router, a KVM switch and top dollar spike protector. Buy a 4 port KVM, even though you need only a 2 port at this time because next year the insidious vBLOtran virus is gonna cause a "virtual power spike" that overrides the spike protector and blows the transistors clean off the mobo in your new machine. The wizards will tell you there is no way a your new machine can be fixed but a month after the 3rd machine is broke in and not returnable, Fairchild Electronics invents the Universal Transistor that can replace ANY blown transistor on ANY mobo.

Of course if she's blonde you can just squirt some dirty oil in the case and tell her the seals blew, the oil leaked out and then the pistons in all the charge pumps ceased.

Diabolical for sure but not nearly as diabolical as some of Honey's tricks :)

I've never done that but it worked for a friend a while back. If I did it Honey would say I had too many crunch boxes anyway and now I just have 1 less which is still too many in her opinion.

I usually don't go up on the roof with Honey but if I have to I don't turn my back on her ;)

Did you run Prime95 on both cores (you need to run it twice)? This would then test both your cores. One core could be fine, one could be bad.

There is no single cause. It could be either or a combination of both. The available evidence does not favor one over the other. Gather more evidence, if you have the time, and the true cause will become more apparent.

Yah but all that indicates is that your system is "pretty good". It doesn't mean it's rock solid. Run 2 instances of prime95 for 6 days and see if you don't get an error.

Without more evidence you have only speculation. One way to get more evidence is to run the apps under a debugger. Or swap out components one at a time to see which one, if any, causes the problem.
