If you are still having these problems, follow my advice. I recommend you making another partition to try this to see what exact drivers are missing! This is loads easier, so you can download the drivers, and follow these steps.
1: Acquire all of your drivers first. Drivers are ESSENTIAL for making your OS work. You can find the drivers from the Toshiba website. Enter your exact model from the service tag, and you can find the drivers for the specific model.
Make a new partition on your hard drive so you can have a safe and "secure" place to store your drivers. Be careful though, when Windows tells you to choose a drive to install Windows on, choose your C drive(or the drive you installed Windows on!)
Most drivers are either 1MB - 200MB, so make your partition at least 10GB - 15GB, just in case.
2: Back up files. This is obviously an important thing. But it seems like you want a full reinstall of Windows without any of your files, I believe, so if I am right about this, skip this step.
3: Just download a Windows 7 ISO from a website. Make sure it matches the exact version of Windows you have(most likely Home Premium.) You most likely have a Windows 7 COA, which has a product key, on the bottom of your laptop. You can use that product key to activate your version of Windows. Windows 7 ISOs are from 3 - 4GB in size. Depending on your internet speed, it may take 5 minutes, or 5 hours. If it takes a very long time, be patient. 4GB is a huge amount!
4: Download VirtualCloneDrive. This is a program where you can make a virtual CD-DVD ROM drive, where you can mount ISOs. No disk or USB required! I used this program so many times when I didn't have a USB or disk on me. It is so helpful!
5: Of course, install Windows. This takes 30 minutes, depending on your computer specs, and how fast your computer is.
6: After it is installed, you most likely don't have much drivers installed. Your resolution made be scaled down to either 800x600, or 1024x768. If this happens, your video driver is not installed. Install all of your drivers that you put on your extra partition you made earlier.
7: If all of your drivers are installed, Windows 7 is up and ready to go! Make sure you download the latest updates from Windows Update.
Hope this helps!
