I will help as much as I can. The major problem is that every system is different and the number of causes of system failure are numerous.
The first thing you should do is ensure you have the latest drivers installed for your equipment. Drivers are such a common cause of problems that there is no need to troubleshoot any further until that step is complete.
Second, contact your PC maker/software vendor for technical support.
The final thing you should understand is that I am not sitting in front of your system. Troubleshooting from a remote location, let alone by E-Mail, is difficult if not impossible to accomplish. I will help as much as I can.
