Random BSODs, BCCode 7a

This one is stumping me. It seems as when the has been running for 15-20 minutes I get these crashes. The first BSOD I encountered was the IRQL Not Less Or Equal. After running memtest (or rather not able to complete it) I replaced the RAM. The computer doesn't crash as often now.

The things I have noticed that it crashes on is running Malwarebytes, running Windows Update, and randomly throughout working on this laptop.

Any suggestions? I'm thinking it's either driver related or a faulty HDD.

Here is more about the one of the errors:

Problem Event Name: BlueScreen
OS Version: 6.1.7600.2.0.0.768.3

First upload your MSINFO32.nfo file.

1. Click on the start button
2. Type "msinfo32" (without quotes) in the search bar of the start menu, click the resulting link. It will open the System Information window.
3. File>Save. In the "File Name" filed, put "MSINFO32" (without Quote), give the save location to desktop, and click the "save" button.
4. Give the time for processing, it will save a .nfo file on your desktop.
5. Zip it, and upload it following the instruction.

Then scan the system for possible virus infection with the following programs.

• Anti-rootkit utility TDSSKiller
• Windows Defender Offline

And finally test your RAM modules for possible errors.

KERNEL_DATA_INPAGE_ERROR (7a)
The requested page of kernel data could not be read in.  Typically caused by
a bad block in the paging file or disk controller error. Also see
KERNEL_STACK_INPAGE_ERROR.
If the error status is 0xC000000E, 0xC000009C, 0xC000009D or 0xC0000185,
it means the disk subsystem has experienced a failure.
If the error status is 0xC000009A, then it means the request failed because
a filesystem failed to make forward progress.
Arguments:
Arg1: fffff6fc00018a10, lock type that was held (value 1,2,3, or PTE address)
Arg2: ffffffffc000000e, error status (normally i/o status code)
Arg3: 00000000ca60f860, current process (virtual address for lock type 3, or PTE)
Arg4: fffff800031428b0, virtual address that could not be in-paged (or PTE contents if arg1 is a PTE address)

I asked for MSINFO to search for something, that's .....

Broadcom 4313 802.11b/g/n driver .... that's old.

Search in Downloads | Broadcom first, and then in HP's site.

The Name Realtek PCIe FE Family Controller network driver is old, too.

Update it from Realtek.

Best of luck :)
