Starting Prime95 Freezes System

I was testing a system for stability with prime95 and for the heck of it, I decided to load it on another system that I have running. This system is very stable. It passes Sandra and memtest86 with flying colors. The problem that I have is that I can't even start prime95 on this system. As soon as I fire it up, the system immediately locks and I have to hit reset. It doesn't make sense to me that I have a system that never crashes on anything and I can't even start prime95 on it.

Any ideas?

All I see is a bunch of .NET Runtime errors. I don't know why I'm getting this and I don't know if this could be my problem.

Could running this system wirelessly lock it up when it's trying to connect to the prime95 server?

 
How do you run it in torture test mode? I didn't see any option for this. The only option that I see is connecting to the server and running whatever they run on the pc.

I can't run it in any mode with this particular pc because as soon as I click on prime95 in start>all programs>prime95, it locks the pc.
 
when you install prime95, you get 2 options, one being "no thanks, benchmark only" or something like that. this is the option i choose when i install prime95. maybe you should reinstall and select this option so you don't have to connect any server.

then you'll see option for torture test in the settings menu. pick the first option to stress your CPU rather than RAM.

I did that. I always pick the no thanks, benchmark only option. I don't see anything in the options that says torture test though. Besides, with this particular pc, I can't even get the options. Just firing up the software locks the pc. I don't even think that it has a chance to run anything at that point.

Does anyone have a screenshot of what this "torture test" option should look like in the menu because I don't see anything.

 
Thanks for the info. I don't know why I'm not getting the torture test option because I instruct the software that I'm just stress testing every time. I do see a option called "test", but it's grayed out. Maybe it's the prime95 software that I'm running. I'll try to download a different version and run it again.

Besides all of this, I still can't run prime95 on this system. I can't even get to the options menu because the computer will freeze before I select anything.

 
I actually haven't re-installed Prim95 in several years. In my experience, it really isn't a very good way to test stability of overclocking. It's way too lenient. I've had systems that would run Prime95's Torture Test for days without errors, but would crash in a certain game in one minute. When I turned off overclocking, the game would run perfectly.
 
Update: I downloaded another version of Prime95 and this version has the torture test. Go figure.. It still locks my pc though before the application gets a chance to get started and the only way to restart it is to hit the reset button. I now fixed the .NET runtime error, so that wasn't causing it. I now have no errors in eventvwr even after the pc is locked with prime95.

Oh well... I guess I won't run it. The pc is stable with memtest, sandra and 3D Mark, so I guess I shouldn't care what's causing this lock up.
 
sanrda and memtest are possibly the single worst tests of stability out there. 3dmark stability is a good sign though. run a few loops of 3dmark, and its as good as anything. also, you can try sp2004, its basically an updated version of prime95, and see if that works out better.
