What kind of graphics card are you using? Double check if it isn't overheating or anything.
You can download various software that could maximize your graphics card fan speed.
Have you tried overclocking your PC lately?
Do you have an Adaptec CD driver/burning program installed on your PC? If so, try removing it completely.
Clean out your registry (using a free program such as Ccleaner)
You could also try system restore to the point, where your PC worked fine
1. Click Start | All Programs | Accessories | System Tools | System Restore.
2. Select the option letting you restore Windows to an earlier state.
3. Select a system restore point on which Windows was working fine.
If the steps above fail to work, try creating another system user profile
1. Log on as an administrative user.
2. Click Start |.
3. Click Manage Another Account | Create a New Account.
4. Follow the wizard.
It's none of these. I reformatted and it isn't my graphics card.
