This computer has been able to run the classic and boinc seti clients with no problems, but some time ago BOINC began to crash [after a version 2 to 3 upgrade i think]. Either client will freeze the computer within a few minutes with no errors logged. The motherboard/CPU temperature shows no abnormal increase. The BIOS settings are in order. This freeze only occurs when running a SETI client, otherwise the computer is stable for weeks running many other programs.

It is a MSI 745 Ultra motherboard, AMD Athlon XP 1800MHz, 2 sticks of 512MB DDR 266 RAM, running Windows XP SP1.

I am confused...you say that you have been running Boinc for some time now, but show no total credit and no recent credit. What have you been running?
Boinc is now at version 4.19 or the newer 4.43 yet you say that you "recently" upgraded from version 2 to version 3?
I think a carefull examination of what you have been running may result in the correct versions and then the reasons for your problems.

Sorry, to be specific neither client has been able to run without freezing since then. The computer in question is actually running under another ID. I have continued upgrading the client though it cannot process any work without freezing.
I just tried the Prime95 stress test which also results in a freeze, so I am led to believe something in the hardware is failing where it hadn't before.

That would be correct, are you overclocking? Did you buy and install new memory? You may need to remove the memory and take it to the computer store and get them to check it.
