I downloaded the climate prediction thing, started it off and it ran for about 5 minutes then it locked up the machine completely, only way to restart was to hit the reset button

this is a 1GHz Athlon, 768MB RAM running Win2K Prof

Why should it stop?

Hi there and welcome aboard,

is your computer overclocked?
I would also check if cooling (e.g. fan on CPU) is properly working.
It therre that there is a stability and/or overheating problem.
Running some diagnostic apps and stability test may help to detect the cause of problem...

How do I find out if my computer is overclocked?
All of the fans are going OK

Usually, overclocking is wanted by the user/owner himself. It means, that you increase cpu and/or ram frequency to get more speed. all you have to do is to check, which cpu you have and what speed you run it.
2nd is: Also without overclocking you can overheat your System by driving it hours and hours at 100%. Often cables inside the PC are the reason why the CPU overheats and stops. You can get Software by your Mainboard-Manufacturer (e.g. ASUS Probe for ASUS Mainboard). This Software tells you, whether System- and Mainboard-Temperature are well.
Mind that there must be a difference of about 15° or more between System- and Mainboard-Temperature.
Good luck - Christoph

Are you running with the graphics/screensaver on? If so, you might want to update your video card drivers to the latest, if you haven't already. Otherwise, the suggestions about better cooling for your system may help.

Guys,

Thanks for these hints and tips

The processor is a 1GHz Athlan running at ~0.9 - 1GHz so I guess it isn't over clocked

It has been running non-stop for about three days but not at 100%. The fans are working

I downloaded and ran a CPU tester from zdnet which just ran for about 30mins (5 mins CPU heat up, 2 mins whetstone, 4 mins whetstone, 8 mins whetstone, 2 mins mmx , 2 mins whetstone etc) NO ERRORS

There is no screen saver, the PC just switches the monitor off after 15 mins of no user activity

Does BOINC interact with other running apps such as Apache or MySQL?

I don´t think so, on my PIII 1266 it runs together fine (4.13 on a debian)

This is the thing.

I'm guessing that the screen saver uses directx (direct draw or direct3d or somesuch)

My graphics driver was out of date and didn't have the windows hardare quality driver thing (WHQ?) DirectX DISABLES things like direct draw.

I downloaded new drivers, installed them, DirectX automatically re-enabled itself and everything works fine now, apart from uploading results and credits and having two computers when there is only one.
