Hello,
I recently was given an old compaq desk pro with a 233 mhz Pentium II processor, I then upgraded it to 512mb of RAM, 120gb Hard Drive, new Case, New Fans, Pentium III 555mhz, and Windows xp Home. I kept the motherboard. It ran fine for a little but then windows gave me a message that my BIOS didnt match the processor. I then decided to take the motherboard that mached the processor to eliminate the problem. It didnt work, i then decided to put the older motherboard back in, now the LED on the mother board will turn on but my power supply fan wont turn on and non of my attached devices will eather (dvd drive, hard drive, fans, ect.)
please Help
