Hi tusharshinde,
Per my understanding that when you log in the report Manager you got the pop-up window ask for credential, you try to enter  the SA account and the window account as the username and password but both not work, right?
Your issue related to the authentication. As you mentioned you have choose the ”Network Service” as the Service account, generally using this account in RSCM and RSWindowsNegotiate is added to the RSReportServer.config file as the default setting. With this
setting, the report server can accept requests from client applications requesting Kerberos or NTLM authentication. If Kerberos is requested and the authentication fails, the report server switches to NTLM authentication and prompts the user for credentials
unless the network is configured to manage authentication transparently.
The issue can be caused by many factors and please check one by one.
Did you enter the username and password for three times and got blank page or got some error? If you got some error, please provide the error information.
you can delete the specific Authorization Types inside rsreportserver.config  file, open path:” \Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\ReportServer\rsreportserver.config”. 
Search the file for the “AuthenticationTypes” section. Remove RSWindowsNegotiate and RSWindoeBasic to ensure only “RSWindowsNTLM” is specified in the file rsreportserver.config file.
Before do any modification, back up the files and remember to restart the ReportServer instance in the RSCM after the modification.
If step1 doesn’t work ,please also do the trusted Site Setting in the Browser, article with details steps for your reference:

Please check the Report Manager's authentication mode.Have a look in the Report Manager's web.config file to check if you can find below information under the <system.web> (Path is “C:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting
Services\ReportManager\Web.config ” ).
authentication mode="Windows"
identity impersonate="True"

Please tried to provide us more details information, if the problem still exists:
Did you login in the report manager locally or remotely via Browser and which URL you are using to login the Report manager?
Did you modified some configuration file before and what did you modified?
Did your windows account have the right permission to access the report manager?
Any problem, please feel free to ask.
