I have an old Compaq Presario 1688 running Win98se. What upgrades can i do do this laptop besides memory? I was planning on buying another copy of XP Pro for it, but looking at how fast it is (400mhz)..i dunno. What can i do to this computer? Current Specs: AMD K6 3D Processor...okay...it wasn't MY laptop. my sisters for college and she "liked the look" 64MB of SDRAM, which is gonna become 128MB + 64MB. Some....CD-Rom.....=c) okay..so i'm not good on specs..but realistically, what upgrades CAN i do to a laptop like this?
