I tried to sign up yesterday, downloaded the folding client and set it to go. Then my system died followed by a restart. The client display wouldn't work, and the CPU started getting real hot and I uninstalled the client after that.

My system is a P4 2.0 with 512 RDRAM.

Anyone else had similar trouble?

F@H runs the CPU at nearly 100%. Looks like the F@H pushed your system into a thermal range that caused the reboot/loss-of-stability.

What kind of system temps were you at both before and after the attempt to run F@H? Sounds like you may not have sufficient cooling in your case or for your CPU...but that's just an initial guess. Would need more info to state that conclusively.

The CPU was running at around 41ºC prior to running F&H, but yeah, you may be right about the cooling. I have a Zalman with the 92mm fan in silent mode which is fine for day-to-day stuff, but there are no intake/exhaust fans in there so air flow's probably not sufficient for intensive CPU work. I'm building up a new case and fans at the moment, so I'll give it another try when I'm up and running.

Thanks for the input.

I have a P4 3.06GHZ and I'm also running F@H. I have a Zalman 7000 ALCU and a modded Enlight PSU and no case fans. My CPU idles around 42 degrees, I have absolutely no problems if I run the Zalman at silent mode. (I run my PC 24/7)

-Check your Vcore, maybe you should lower it, or set it higher
-Maybe you have a problem with your memory timings or
-maybe your mainboard has a wrong setting for the max temperature of your CPU, and thus rebooting your system.
-Maybe you have a PSU problem?

If that doesn't help I'd suggest to run the PC with the case open, until you can use your new case.

Oh dear, sounds like it could be more serious than I thought. I'm not sure what memory timings or Vcore mean, and now I've uninstalled F&H, CPU temp is back to 42ºC. Seeing as the problem only occurred when I was running F&H, the simple solution seems to be to NOT run F&H, so I'll leave it for now until I get the new case up and running.

Thanks for the feedback.

For a quick check on whether heating is the problem, run F@H with the case open and a large fan blowing into the case. If it's stable that way, then CPU overheating is the obvious suspect.

Other possibilities might be flaky power supply, bad memory, in addition to all other suggestions here. There are many utilities you can use to isolate the problem if you so desire. MemTest86 is my favorite for testing memory. It boots from floppy or CD and does not run Windows, so you isolate a lot of driver / OS / graphics card issues. For power supply, the only thing I can suggest is to do a swap with a known good unit.

It's better to fix the problem if possible, since you never know when your system might become unstable and crash.

I thought maybe you changed the memory timings and Vcore, but if you don't know what they are, you wouldn't have changed them. Vcore is the current voltage of the CPU. If it's set to low your system might reboot if the CPU is under full load. (the CPU hasn't enough energy in that case) Maybe your mainboard has set it to low, or your PSU is faulty. I think you can check it with motherboard monitor 5.
I had some trouble with the Vcore also, because the CPU was undervolted. When I started F@H the system would crash, sometimes right away, or sometimes after half an hour.
The Vcore should be between 1.47 and 1.53 volts. If it's lower you can change that in the bios.
If that doesn't help you should check your memory like Lenny said with MemTest and if that doesn't help I think it's your power supply.

You should fix your problem, you don't want your PC to become unstable and crash and lose all your data.
