Question Errors on a new computer

I've been running the program for six years or so, and so when I got a new computer last week I installed it. I am using v 23.7.1 of the software and the computer is an Athlon 2800. I've never seen error messages before, but now I am getting some sort of error roughly every 40000-70000 iterations. I get one of two messages:
Iteration: 4669424/20419339, ERROR:SUM(INPUTS)!-SUM(OUTPUTS),2334581124007200!=2335680635635001
Possible hardware failure, consult readme.txt file.
Continuing from last save file.

or:

Iteration 4725028/20419339, ERROR:ROUND OFF (0.5) > 0.40
Continuing from last save file

I looked at the readme which reccomended a torture test. I ran the torture test for 20 hours, and got no errors and no warnings. I started back on the number it had been working on, and I get the errors again. What does it all mean? What should I do? Any advice would be greatly appreciated. Keep in mind I am far from an expert on the program; I just like math and run the program for kicks. Thanks!

This first error is relatively benign. It is probably being caused by a sound card driver that is not properly saving and restoring registers.

This one is more serious. Unless, it is followed by a message that says it is reproducible and not a hardware error. Could be heat related. Try running with an open case, even a fan blowing at it. If the error persists, try to get the machine replaced. You might consider that in any case

No message follows either error other than "continuing from last save file" and "resuming primality test...". I bought the computer from Alienware and it supposedly has special construction and fans for optimal cooling. It would be awfully surprising if it was overheating especially since I haven't done anything to it since it was shipped (i.e. overclocking).

If I should try to get it repaced, at least Alienware supposedly have a good reputation for customer support, but I can just imagine trying to explain to them what my complaint is. Is there any way to more specifically diagnose what my problem is, either with Prime95 or some other testing software or some other method?

I have never bought a system from alienware, but with the reputation they have, i would even expect that they actually use prime95 to test their systems before shipping, so they should understand your problem.

Perhaps they preset too aggressive memory timings in your system? Do you have the experience (and want to) relax the memory timings in the bios a bit? The memory timings once (with a homebuild system) were the cause for an error with with prime95 with one of my systems...

When it comes to the finer points of computer construction and performance I have little experience and less courage. All I really wanted was a boring old Dell, but my friend talked me into shelling out for an Alienware so I could get better performance and support and less chance of problems. Anyway, if you can direct me to a basic explanation of how to do what you reccomend I'd give it a shot, otherwise I may just call their tech support and drop it in their lap.

Thanks again for the help.

Try updating all drivers, including the motherboard drivers.

Do a Memtest to check your Ram.

Get a monitoring program to actually watch what the CPU temps are.

If it continues, take one add-on card out at a time and run Prime95.

Hmm, well - even if i think i would be able to do some tests with your system if i had access to it, i am afraid that trying to explain this in a forum in detail is too complicated and could lead to more confusion. You got some more hints from outInder, but they also involve system changes.

My suggestion is, that you at least give Alienwares tech-support a try and explicitly mention the prime95 problem. If they have not outsourced their tech-support to some obscure company in some obscure country, i seriously cannot imagine a self-respecting support-engineer without personal prime95-knowledge.

If they have no idea or have never heard about prime95, we will try to find a solution here.

I personally think about buying a gaming-notebook from alienware here in germany next year, but - honestly - if they don't even know prime95, i will not do that.

That leads me to another idea - how about a small red sticker ("GIMPS torture tested") for system integrators?

I'll take your advice and give them a call. I sure appreciate each of you taking the time to reply. I'll post a followup when I hear something from them.
