Hello GhinasTCPutra.

Install Service pack 1 and all other windows updates. Otherwise the system will remain vulnerable to threats.

Code:

Windows 7 Kernel Version 7600 MP (8 procs) Free x64
Product: WinNt, suite: TerminalServer SingleUserTS
Built by: 7600.16385.amd64fre.win7_rtm.090713-1255

Service Pack Center - Microsoft Windows

The BSODs are being caused by NetGroup Packet Filter Driver, which is a part of the WinPcap packet capture library.

Code:

BugCheck C1, {fffff98017b2af90, fffff98017b2af85, f54074, 23}

*** ERROR: Module load completed but symbols could not be loaded for NPF.sys
Probably caused by : pacer.sys ( pacer!PcFilterSendNetBufferLists+29 )

And the driver is very old.

Try to update it from WinPcap · Commercial and Community Support.

The realtek network driver is also crashing.

Code:

fffff880`097f3600  fffff880`0564e6d0Unable to load image \SystemRoot\system32\DRIVERS\Rt64win7.sys, Win32 error 0n2

And it is old, too.

Update it from Realtek.

Let us know the results.
