Not much help here but your RAM is far to high for Windows 98 or ME never go above 500mg for these OS i run 250mg.
Why are you running two hard drived total 200GB well over the top for home use have you got your jumpers on the correct pins IE MASTER and slave??
Try taking one hard drive out.
There are people far more up in IT than me so they might be able to shine a light on your problems.
