Seems like you are sorted however I recommend you to carry out the additional checks in my guide mentioned above by Osprey4.
See Windows Reinstallation Guide/A Clean install of Windows Vista (page 144):

Step 1-6 are steps for preparation before OS Reinstallation i.e. backing up, obtaining media and drivers. Step 7a is an advanced format. Step 7b doesn't apply to your system. The Guide you used on Black Viper is equivalent to Step 8 of my guide. Step 9 is installing major OS Updates, Step 10 the system drivers. Likely you have done all this correctly.
Ensure that your product is activated see (Step 11a), also on the screenshot ensure that you have Service Pack 2 installed and that there are no errors in the Device Manager (Step 12). You should also have Internet Explorer 9 installed. Step 13-15 are optional but recommended. Step 16 you should carry out. Step 17 is optional as is Step 18-21.
