I have a Gateway 500L with an Intel P4 1.6ghz, 256mb, 400mhz fsb processor. The mobo is Intel D845PT. I wanted to upgrade the processor to 2.4ghz, 512mb, 400mhz fsb processor (SL6S9). I have downloaded the latest bios, which Gateway says will support this processor. Intel also says the board will support this processor. When I install the processor with heatsink and fan I get nothing. No fan or other noise. The mobo power light is on but no test light or power on the power supply. The light on the computer power button is amber.
When I remove the processor and replace it with the 1.6 processor I still get nothing even with the 2.4 heatsink and fan. However, when I put the computer back to its original configuration, (1.6 cpu, original heatsink and fan) the computer powers up and works fine.
I am curious whether the power supply is sufficient to power the fan and 2.4 cpu. It is a Gateway original rated at 160 watts. This has always seemed small to me, but it powered the 1.6 P4 just fine. I am open to any suggestions. I bought the cpu second hand along with the fan and heatsink. Any of those could be defective, although I was told they were from a working pull. Any suggestions on testing cpu, fan or both?
