First clear the CMOS and see if that fixes your problem. If clearing the CMOS did not fix the problem then either the processor, power supply, motherboard, memory, or video card could be faulty. In some cases when a power supply or processor dies there is a possibility that it could have damaged some other computer component such as the motherboard also. But before you do anything check and make sure you have the FSB speed set correctly on the motherboard equal to the rated FSB speed of the processor you purchased. Usually the FSB speed can be configured using a group of pins on the motherboard designed for this specific task or somewhere in the CMOS setup. Also make sure everything in the computer is installed and jumpered properly and there are no foreign metal objects shorting out the motherboard. >From: Timothy Phan <[log in to unmask]> >Reply-To: PCBUILD - Personal Computer Hardware discussion List ><[log in to unmask]> >To: [log in to unmask] >Subject: [PCBUILD] Computer Boot-Up Issue >Date: Fri, 15 Aug 2003 13:52:19 -0500 > >PCBUILD, > > Hi, I just bought a power supply and a CPU and connected it to my >computer.
