Did the HD tests pass as well? And did you have a clean drive you could perform a clean install of WinXP on, update it, and run Rosetta v5.25 on Boinc ver 5.4.9 and see if something about your Windows install or Boinc/Rosetta installation is corrupted?

If memtest runs without error I may give Rosetta another try. I'm having no problems on the other system

memtest86 ran for 21 hours before I shut it down. 0 errors
This system will go back to F@H for Team Helix and the pentium4 box will work on Rosetta.

Thanks again for the input.

In the last few weeks, I upgraded one system with a new CPU and "Better" memory. When I first started it up, Einstein was happy but Rosetta would fail. I ran Prime95 and it failed. I changed memory timings several times and running Prime95 between tweaks. Prime95 would either fail in an hour or run for several hours. I find that a 4 hour test is usually sufficient. However, when I ran Rosetta, it would run a few successfully and eventually it would fail and succeed again. When I ran Einstein, it wouldn't fail. I even had Prime95 run for 18 hours without fail and then ran Rosetta with some successful and then Rosetta would fail. Out of desperation, I bought some more memory. It could have been a bad CPU or a bad power supply not able to run the new CPU.

The memory was the problem. The better memory wasn't better (PC3500 instead of PC3200, both good named brands). The better memory was unstable. I ran the memory with settings so relaxed that I swear I saw some bits stretched out on the sofa. Running the specified tighter memory settings didn't make it more reliable. I didn't try overvoltage since I was running stock speeds.

Prime95 is not PROOF that a system is stable. Prime95 is like the Olympics. The Olympics only proves who is the best athlete in that sport for that day. Prime95 only shows the results for as long as you let it run or it finds an error. However, Prime95 is still a good indicator. But I now look at it with less certainty.

I now consider Rosetta a better indicator of a stable system. If it has errors, the system is unstable. There were no other symptoms of "bad memory".

Oh, and good luck.

Hello murky

All though it has been a while I cannot remember if I also mentioned I had some sidebyside error messages, these stop me installing things likt mice and usb drives properly.

These are not related to the Rosetta@home program crashing as it did not crash for me.

But I can tell you how to fix it
http://www.dlldump.com/download-dll-files_new.php/dllfiles/S/syssetup.dll/5.1.2600.2180/download.html
Get that file and save it and overwrite the one in c:windowssystem32

I'm guessing it got damaged and or reverted to an old version, possibly using programs such as Vista Transformation pack, or Icon file modifier packs.
