I too have been doing a RAM upgrade recently.
133 Mhz RAM will work on 100 Mhz FSB, but it (the RAM) will only run at 100 Mhz.
My advice:
- Reseat the RAM very carefully just to be sure.
- Check the manual to ensure the DIMM will take a 256 Mb stick.
- Is the memory stick parity / ECC ? What about the others ? The 2 cannot be mixed.
- Check the bios. There are many bios settings for tweaking RAM. Settings to check are CLS (latency : usually either 2 or 3)
Also, in the bios, see if you have a RAM speed setting. If so, set it to 100 Mhz
To be honest, the symptoms you describe don't sound memory related to me.
Have you made any other system changes recently ?
Do the problems go away if you remove the new RAM stick ?
If you get really stuck, try asking some of the guys on this forum:

They know what they're talking about and will help you if you give them as much info as possible.
I had some problems recently due to my PC and processor in particular getting too hot. They really helped me out.
Good luck
