Pc Locks Up

I'm running a fairly fresh install of win7 (installed 2 or so months ago) which lately has been randomly locking-up/freezing. I don't even get a response from ctrl+alt+del, so I'm forced to do a hard reboot.

Anyway I looked in events viewer and wondered if these instances had any bearing:

The browser service was unable to retrieve a list of servers from the browser master \\BONSAI on the network \Device\NetBT_Tcpip_{############################}.

Browser master: \\BONSAI
Network: \Device\NetBT_Tcpip_{################################}

This event may be caused by a temporary loss of network connectivity. If this message appears again, verify that the server is still connected to the network. The return code is in the Data text box.
---------------------------------------------

Basically this "BONSAI" is just another user on the network.....why is this user the "master browser"!?

The resulting error from this warning is as follows:

The browser service has failed to retrieve the backup list too many times on transport \Device\NetBT_Tcpip_{###########################}. The backup browser is stopping.
---------------------------------------------

Of course the freezes could have nothing to do with this but it seems odd and my pc is well looked after.

Hello,

When do these freezes occur? Try opening an elevated command prompt and running sfc /scannow.

Just at random, I haven't noticed any relations. I ran the scan and it completed successfully, saying that all was well:

Microsoft Windows [Version 6.1.7600]
Copyright (c) 2009 Microsoft Corporation. All rights reserved.

C:\Windows\system32>sfc /scannow

Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection did not find any integrity violations.

C:\Windows\system32>

this should help

Computer Browser

What does this mean?:

The master browser has received a server announcement from the computer BONSAI that believes that it is the master browser for the domain on transport NetBT_Tcpip_{##################################}. The master browser is stopping or an election is being forced.

Unfortunately its not helping much, win7 doesn't seem to like the command prompts and I can't find browstat?

go to the BONSAI machine and in services.msc disable "computer browser" service and restart all machines

I'm a student in shared accommodation and It's not my pc, so getting access to it is not really an option.
