Follow Step 8 and Step 9 properly as they are very important ones when dealing with Windows 7 Home Premium.
Reason: Win 7 Home Premium does not support Windows authentication as it is available in Professional and Ultimate versions, so in order to make SharePoint run properly you need be extra careful while step 8 and step 9.
However, you have done everything properly and installed SharePoint properly with all its pre-requisites and then when you try to open Central Admin or your root site, you get a blank page, try the following things:
– Go to IIS Manager, and select Sites > SharePoint : 80
– Double Click Authentication and Right Click on Basic Authentication and enable it.
– Try logging in to central admin with your system admin account. If this does not solve your problem, try next one.
– Disabling LoopbackCheck
– Follow Method 2 from this url http://support.microsoft.com/kb/896861
Hopefully this will solve your issue.
