Here’s a guildeine to help with your decision:
Windows XP has about 900 days remaining until official End-Of-Life date so it’s time to start thinking about it now. If you still own a pc with a white/cream coloured exterior case, you’re well overdue for a new system.
If the computer having trouble is less than three or four years old, and if budget is an issue, update it with a new operating system, memory or a new larger hard drive.
If the system is more than four or five years old, it’s time to stop investing good money after bad and think about replacing the whole machine.
If the motherboard is giving you trouble, and if the system is no longer covered by a manufacturer’s warranty, replace the workstation. The parts and labor cost almost never justify such a fix on an out-of-warranty computer.
If a three- or so-year-old system requires only a small fix like a power supply or inexpensive RAM upgrade to provide another year or two of service, those fixes should be made but remember, the system is running on borrowed time.
