I have a compaq presario windows 98 and im planning to upgrade it in every possible way i can (including case and etc.). im planning on buying a intel pentium 4 but im not sure it would be compitable with the current motherboard i have. the computer itself is in pretty good condition except i fried the power supply. i would also appreciate any advice on what upgrades to buy. the pc would mostly be used for gaming,internet, and homework.
