Stress testing computer

[baggins2000]

Hello,
I am looking for ways to stress test a computer thoroughly and was wondering if there is a package or distribution which aready does.
The problem we have is that computers will fail randomly. Many just lock up. We take the system and run it on bench, various tests provided by Dell and all seem to pass. Then we put system back into service and the system fails again.
So what I am looking for is a way to stress test a system to see if I can find what causes the failure.
I am familiar with memtest, but what about the CPU, NIC, Bus.

Your best two options... Prime95 or OCCT

memtest for windows is pretty good too, but it's more based on testing the memory while it uses a good amount of processor power to do so (2 threads per memtest) whereas prime95 uses all of the CPU and just some of the memory. Prime95 and OCCT are really hardcore, and memtest is a medium-ish one.

http://hcidesign.com/memtest/download.html This is for windows, not the bootup disk.


I would first run prime95 for 8-10+ hours. If it doesnt crash, and all threads continue to work after all of that (open prime and look at the window status) then I would run memtest. If you have 6 gb ram, then run 2 windows of 2000mb in each memtest. If you have 12gb, then run 4 or 5 windows of 2000mb each (every bit you can spare), and if that lasts for 8+ hours then that's stable too. If you're PC makes it through all of those 18 hours of testing, then I don't think it could be any MORE stable.

Check HWmonitor http://www.cpuid.com/softwares/hwmonitor.html and check the fluxuations in the power voltages before and after tests, and the temps of the system/cpu/HDD. It'll tell you the lowest and the highest and the current.

On the OCCT link theres seem to be a virus in the download section.

If you read the main page, it is giving a false positive for a virus. It should be safe or Google OCCT and find an alternative site to download from.
