Ok. here is my prob, I have an uncached speed of 1.67 megabytes per second. Similar systems to mine have an average of 2.42 MB/s.

How do I bring this up to about the same rate?

I also suspect it's the cause of my favorite game crashing.

Also I am seriously considering reformatting my pc and reinstalling my win98 cd to make my pc fresh like i just bought i may have to wipe everything out and i need to know how to do it. I know u have to write the hard drive to all zeros, but I dont know the first thing to do. Can anyone please give me detailed step by step instructions on how to wipe my system clean, and reinstall my OS, so its like brand new? (in case i really need to do this)

 

please can someone help me with this?!!

 

I maybe wrong but cache speed is generally dictated by your hardware. If you have an older slower hard drive that's the way it is.
As to it causing games to crash, I doubt it, make them a little slow loading but doubt it would crash them

 

Adjusting such could cause problems also. If you are unsure, then I suggest you dont do it.
