I just put together a system today and I want to find out a few things.

Ok i got a 2100xp,TT Volcano 6++,gigabyte GA-7VRX Mobo,320wattPS,256crucial 2100ddr,Maxtor 40gig 7200rpm ata133 HD,32mb sis 305.

Ok ive been running into some problems. Motherboard is set on default bus speed of 100, has a switch on mobo to set to default 100/133 speed. I can also adjust it in bios much past 133 although im not an overclocker(dont want to be) im not really sure what the bus speed even does when you crank it up.

So what should this be set at 100 or 133? When it is set on 100 i get a read out of 1500+xp and everything runs fine with about 40/50*c.
When i run it at 133 i get the actually speed read out of 2100xp it runs about 50/60*c. When its running at 133 it seems to get lockups and errors when installing things etc.

What should i do, could it be caused by the heat? or am i not supposed to be running it at 133?

My house is pretty hot where the PC is so its kinda hard to keep it super cool, could that be a problem?

I was also wondering about running HD in ata 133. Does windows XP automaticly set it for the best speed or is this done manually?

Thats basicly all i really was wondering. Thanks for the help in advanced
