Well this is my old desktop and its like 9 years or more, So many issues have been here and still its stable and working. As i have only two years left in high school and leaved this my computer and have a new laptop.
1GB of Ram....you should be very carefull with your Ram Usage.
When I had 2GB RAM on XP SP3,I've stoped some "not need it" services from running.... I remember that I had like only 10 processes while "on idle" in my task manager
Thanks for the suggestions but 1GB is enough for me actually I use only for having some school works during school days and I didn't played games here nor installed caused surely the issue will persist but now none.
Can only change your cpu if your mobo allows it. But most of the modern day cpu's are not compatible with your current mobo. So you really need a whole new pc.
I mean is that the CPU is new all are new even the motherboard will change to new and probably no longer as P4 (that mobo last change is like 5-6 years)
