I am having a delimma with my Dell Optiplex GX1. I have an old slot 1 pentium 2. When I turn on my PC I get an error before the system boots! It reads this. Memory write/read failure at 0c8084fc, read 806fa06f expecting 806f806f. Decreasing available memory. The amout of system memory has changed. I am pretty sure that these are an I/O address but I am not sure what they mean! Can anyone help?
