Most of the time your BSOD code is due to a bad driver. For more info try googling stop 0x000004e

Although it could also be caused by hardware, Ram and HDD would be the first Hardware that I would check.

What driver did you last install / What Hardware did you last install?

It was the graphics card drivers I believe I installed last.

It may be unrelated but one of my hard drives has become louder than usual, could that be an issue?

Could be either, For the hard drive It sounds like you have more than one, could you operate with only one of them installed? In other words unplug the hdd that's making the abnormal sound, or is the noisy hdd the OS drive?

You might also want to go into your MOBO bios and check the voltage of the 12v rail. You have a lot of HDD's and stuff for running only a 650w, it SHOULD be enough, but it is close. The 12v should be within 10% according to manufacturer spec, but you could see problems if it is more than 5% from spec so between 11.40v and 12.60v

Well I'll check graphics drivers for it, otherwise I know which drive it is and unplugged it before to check, I have 4 drives including 1 ssd.

I'll have a look at voltages later on and see what's what. I've never modified things like that before so excuse me if I ask a stupid question :)

I'll post back my results later on.

Please follow the to provide us with the crash reports. For driver issues, it is a shot in the dark to determine which driver is causing it. Same thing for hardware. Your blue screen is usually related to memory problems or drivers, so to narrow down which, we really need your crash reports from following those instructions.

Thank you.

Possible causes are Memory problems... Drivers...

Thanks to Dave76 for help understanding possible causes.

We will start with the common problems first (see bold possible causes). Do the following steps and test after each to see if stability increases (the memory tests you can run concurrently as they will not increase stability unless you are forced to move modules around). Post back your results after each step, and if you get a blue screen crash, upload the files again and await further instructions after we are able to analyze the crash.
  • If you are overclocking any hardware, please stop.

  • Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).

  • An underlying driver may be incompatible\conflicting with your system. Run Driver Verifier to find any issues. To run Driver Verifier, do the following:
    a. Backup your system and user files
    b. Create a system restore point
    c. If you do not have a Windows 7 DVD, Create a system repair disc
    d. Run Driver Verifier

    If Windows cannot start in normal mode with driver verifier running, start in safe mode. If it cannot start in safe mode or normal mode, restore the system restore point using System Restore OPTION TWO.

    Thanks to zigzag3143 for contributing to the Verifier steps.
    If you are unable to start Windows with all drivers being verified or if the blue screen crashes fail to create .dmp files, run them in groups of 5 or 10 until you find a group that causes blue screen crashes and stores the blue screen .dmp files.

Also, update your netr28x.sys driver. I know it has an update because I have a similar device in my machine.
netr28x	fffff880`058ee000	fffff880`0598d000	Wed Feb 25 20:02:09 2009 (49a60631)	000a3bdb		netr28x.sys
You may use the following sites as references for finding drivers. We recommend finding the manufacturer of the driver and downloading drivers directly from the manufacturer or software developer. If you have trouble finding a driver or driver manufacturer, let us know and we will do our best to assist you. If you need help, please provide the device name, manufacturer, and the driver .sys file that you are looking for.
  1. Driver Reference is a good site to find the driver .sys files, their descriptions, and the site most likely to contain an update.
  2. Driver Search Methods provides driver manufacturers and links to their homepages.
There are a few methods for updating drivers.
  1. Installing and updating drivers in 7
  2. Driver Install - Add Hardware Wizard
  3. Driver Install - Device Manager

To fully re-install a driver, use the following steps.
  1. Click Start Menu
  2. Right Click My Computer/Computer
  3. Click Manage
  4. Click Device Manager from the list on the left
  5. Find the device you are trying to uninstall by expanding the appropriate set of devices
  6. Right click the device
  7. Click Uninstall (do not click OK in the dialog box that pops up after hitting Uninstall)
  8. Put a tick in Delete driver software for this device (if this option is available, otherwise just hit OK) and hit OK
  9. Restart your computer
  10. Install the latest driver for the device once Windows starts.

  1. Login as an adminstrative user.
  2. Click Start Menu
  3. Click Control Panel
  4. Click Hardware and Sound
  5. Click Device Manager (the last link under Devices and Printers)
  6. Find the device you are trying to uninstall by expanding the appropriate set of devices
  7. Right click the device
  8. Click Uninstall (do not click OK in the dialog box that pops up after hitting Uninstall)
  9. Put a tick in Delete driver software for this device (if this option is available, otherwise just hit OK) and hit OK
  10. Restart your computer
  11. Install the latest driver for the device once Windows starts.

I ran the memtest86+ test for 30 mins yesterday and it was ok, I'll be running it longer tonight.

I did the driver verifer task, it lagged my system on bootup and was laggy using it too. I had one BSOD from the verifier going and I attatched another BSOD zip to this post.
