Coputer turns off

(moderation:
Hello guys,
my computer suddenly turns off when running Einstein applications - and only Einstein apps. This doesn't happen with other boinc apps. I proved this serveral times running different apps, it turns out that Einstein causes the problem.
The ugly thing here is that windows does not shut down or suspend - the computer just turns off. So I get no error message or something else.
Application: Hirachical S5 all-sky GW search #5 3.05
Can someone help me?
Thanks,
Joe

How should somebody help you?
We have no informations about your host or used software inclusive firewalls, virus-scanners or sec-suites.
First i would restart this host without Boinc running. Then check the entire system and all system-logs for an failure.
You should clean the inside

You should clean the inside of your computer (chase out the dust bunnies :-). Einstein tasks tend to produce more heat than many others and some machines just switch off when overheating.

If the problem is a bluescreen then this tip might help you get a chance to see it!

Well, usually after a bluescreen the PC reboots rather than shut down, so I also suspect a problem with either
a) excessive heat causing a protective emergency shutdown as Gundolf wrote (dust blocking airflow, failing fans, failing temp sensors, ...)
b) under-sized or fading power supply unit
No matter how buggy an unprivileged program might be (and the E@H app is really quite stable and is NOT known to crash easily!) it will never ever cause your PC to shut down just like that because if the Operating system would allow that, you'd see a lot more viruses that do just that :-) . Only very special processes have the power to do that.

Other apps (like milkyway for instance) had run many hours each day on all CPU cores, so neither the CPU temperature nor a under-sized power unit can be the problem.
The PC suddenly turns off, no blue screen.
I wonder, if Einstein could do that. Hope it's no virus!
RE: ...so neither the CPU

Who tells you that? I have made the experience that my computer runs hotter when Einstein runs than when SETI runs.
That's exactly what my laptop did when it got too hot, before I cleaned it.
And that's exactly what I told you earlier, if with less words. :-)

There are plenty of freeware

There are plenty of freeware tools available that will display the CPU and/or motherboard temperature (google rules). You may want to use one of these to check the cooling of your PC.

Or just use one made by a BOINC fan: http://efmer.eu/boinc/index.html
Although I still use Motherboard Monitor 5.
There may still be a warning about this in your Event Viewer.
Click Start, and then click Control Panel. Click Performance and Maintenance, then click Administrative Tools, and then double-click Computer Management. In the console tree, click Event Viewer. Then check the System and Application logs on around the times you had these shutdowns.

As Ageless suggested, check the Windows Event Viewer. My guess is you're going to see a message stating something like "... the last shutdown was unexpected.".
If so then the problem is most likely not with Windows or the EAH app. More likely the PSU is starting to get flakey. Many late model PSUs will automatically just turn themselves off with no warning when they detect what they see as 'abnormal' load and/or operating (internal temperature) conditions. It's possible that as the supply has aged, it is getting more sensitive to these conditions.
Another possibility is there is an excess dust buildup inside the PSU itself. The first thing I'd try is taking the supply out, open it up and give it a good cleaning inside (including it's fan). Just be careful around the filter capacitors. ;-)
While you have it open, also take the time to inspect it for bulging/leaking caps, signs of overheating components (discoloration of the component and or PCB area around it), and other obvious defects. A good magnifying glass comes in handy for this phase of the operation! :-D
Ordinarily, blowing it out from the outside is sufficient, but a lot of times you can eliminate problems like this in otherwise good 'high mileage' units with an in depth cleaning. :-)

Thanks to you guys!
I have tried the 'efmer' tool, but temperatures are ok at all times (~65-70°C).
I found no message in the Windows XP event log witch tell about a shutdwon or something like that.
