There are hundreds of PC help websites, some of which require a subscription (although I wouldn’t recommend these). You should decide for yourself about the value of specific websites, but I recommend the following sites.
Tom’s Hardware is a long-standing website devoted to hardware and hardware problems. This site includes extensive forums containing a huge wealth of information, and experts are always available to help diagnose and fix difficult problems.

Run by the people behind Tom’s Hardware, Computing.net is an excellent resource for help with complex and difficult PC problems.

Steve Gibson is a well-respected IT security expert. On the Gibson Research website, he provides many tools to help diagnose and repair security flaws in your installation of Windows.
Graphics card problems are common with Windows. Fortunately, there are only two major manufacturers providing the core hardware for graphics card technology, so help is centralized. You can find support for an ATI-based graphics card at the ATI support website.
Similar to the ATI support page, the nVidia support website is the place to visit if you have an nVidia-based graphics card in your PC.
The Microsoft MSDN site offers an extensive section for diagnosing and troubleshooting Windows 7. This includes the Windows Troubleshooting Platform (WTP) that enables system administrators to write custom troubleshooting packs.
