This is the computer I equipped four years ago. Where do I need to upgrade?

There should be no problem opening the webpage. If there is a problem, you need to find the reason.

1. Clean the main chassis first, blow dust with an air gun or a hair dryer, and carefully clean the motherboard, hard disk, memory, power supply, hard disk, graphics card, etc. And then replace the cooling silicon juice of CPU with a new one.

2. Reinstall a pure system, try not to install ghost version, then install various hardware drivers and update patches. It is recommended not to install useless software, and don't learn that some people seem to be in a hurry to install all possible software. In principle, what is installed is used.

3. If possible, buy a 4G memory, upgrade to 8G, and form dual channels.
