I am sure that there has been another question like this, but I am unsure if I was following the recommendations correctly. So, I will give my scenario, and hopefully we can work through this. I recently upgraded my cpu. I changed the processor from Intel E8400 to Intel Q6600. My mobo is the Asus P5G41t-M LX PLUS. This mobo supports this chip according to the Asus support page. I have a 1TB sata had, a 600watt thermaltake psi, 2 4GB ram sticks, and a Nvidia GeForce GT430. Now, before I installed the new cpu, the pc ran great. Many games ran ok, but I wanted to try the quad for testing purposes. So when i purchased it, I turned off the power. Unplugged the machine, and very carefully while being grounded, removed the cpu cooler, and the old cpu. I put in the new chip, and replaced the cooler. I plug everything up and turn on the pc. And to my shock, no keyboard, no post. But, upon checking each component, via breadboard technique, I find all components working. I rebuilt the thing. Then by accident, I hit the reset button. It posted! But I got a bsod. I heard that the gpu could be a factor with new cpu. So I restarted, and tried the onboard gpu. Now it won't post. Same issues as before. Nothing is shorted out. So, I need to start over. Can anyone give me a in-depth step by step guide on how to clear cmos?
