What is the +3.3v,+5v and +12v refer to in the asus probe voltage monitor software refer to and can or does it have to be configured...my +3.3v is registering 3.584 but twice it went to 3.6something wherein the asus probe popped up to warn me and part of the monitoring wave on the 3.3v scale turned red and I imediately crashed and couldn't reboot. The first crash cost me a new athlon 1Ghz 266Mhz cpu and the second crash nearly cost me a Duron 800Mhz I cleared the cmos at the jumpers both times(as learned at this site...thanks to the posters). I was using a pc 133 256 sdram when these crashes occurred...I reinstalled three pc 100 sdrams and havn't had a recurrance...does the ram have something to do with my problem. Also can I run a 1Ghz 266Mhz processor safely on the a7v133a motherboard without changing the board, mechanically? I would greatly appreciate any help concerning these issues...waiting patiently...Thanx
