Re: PC only boots if I disable CPU cache

As for your question about level 1 and level 2.
Here's the long answer


The Short answer is: (Level 1 cache) A memory bank built into the CPU chip or packaged within the same module as the chip. Also known as the "primary cache," an L1 cache is the fastest memory in the computer, and it is closest to the CPU. The L1 cache feeds the processor.

(Level 2 cache) A memory bank built into the CPU chip, packaged within the same module or built on the motherboard. The L2 cache feeds the L1 cache, and its memory is slower than L1 memory. The L2 cache feeds the L1 cache, which feeds the processor.

So you can see where there is a performance hit. Is everything thumbs up with your CPU heatsink and fan? Has it see any compressed air in the last 5 years?

As Windows does actually come up can I assume that the Harddrive, motherboard and RAM are OK, and that the CPU is likely to be the faulty component ? I did wonder whether it was a power supply problem, but I have tried substituting another PSU, but it had the same results.
