Well I had to be the bright guy, now i'm paying the price. I have an AsusA7V133 at work that said it had a clock multiplier of 10x and a cpu frequency of 100. The same MOBO as home said 7.5x and 133 respectively so I decided to change one at work since home unit seemed to work better..BAD IDEA. After changing the settings at office computer to home settings the computer went off and I don't know how to get back to original settings. Both stations are using an Athlon 1000 and there is PC-100 memory at home and PC-133 at work. I'm in a hurry to fix as I have several important jobs to finish tomorrow. Thanks for help now and later.
