Also, go have a quick look for a solution yourself. Google is a great way to find information. Most of the time a simple Google search will give an answer or at the very least point you in the right direction.
If that fails, then ask away. Try to provide the following information where possible.
- Operating System
- Software
- Drivers
- CPU
- RAM
- Motherboard
- Video Card
- Virus Software
- Firewall
