IBM ThinkCentre A50p - Shared System Memory, Be careful what you mess with!

I just formatted an IBM ThinkCentre A50p 8194 and installed WIndows xp on it and installed everything and it was working smoothly with the drivers from IBM website. I have done this to this same model of pc many times before with the same result. This time however I went in the bios and changed properties for the Video Setup of the Intel 865G Graphics Chip. The 'Shared System Memory' was 16Mb and I made it 32Mb.

Now whan I try to log in I get a 'User environment' titled window saying "Windows cannot load the user's profile but has logged you on with the default profile for the system. DETAIL - Insufficient system resources exist to complete the requested service." This window has a count down timer for about 30 seconds after which it will disappear if you do not click OK for it to close. This is followed by another prompt titled 'userinit.exe' that says "Application failed to initialize properly (0xc000012d), Click on OK to terminate the application." and then an OK button. All you can do is click OK on this window and then a blank screen with the pointer shows up indefinitely. The system still responds to ALT-CTRL-DEL and you can restart or log off and try to log on again. If you do try to log on again, some buttons or text disappear each time you try to log on until you eventually get no response. Changing the value back to 16Mb in the bios fixes this problem.

This is another example of how one setting can mess up a system but not permanently.
