And your old one was:
PEGAGFN.sys Wed Aug 5 01:50:46 2009 (4A791DB6)
So you've updated it as far as you're able - and you've replaced the old one, so if it was causing errors you've now got a fresh copy.
Lets see what happens next. Wait for another BSOD.
So far so good, how shall I test for a BSOD? I'd rather not use the Driver Verifier, I don't want to kill my laptop.
In general I estimate that if you go a week without a BSOD, then it's probably fixed.
Then if you go 2 weeks - it's most likely been fixed.
Happening again, I have a strange feeling its because I have 2 video card drivers installed. One from from Toshiba, and one from AMD. I installed them both, should I remove AMD drivers because it wasn't meant for my laptop.
I would suggest trying these free diagnostics: Hardware Diagnostics
Also try running Driver Verifier according to these instructions: Driver Verifier Settings
My own computer system refused to boot today, so I'm using the wife's for right now.
I don't know when I'll be able to fix it, so until then please be patient with me.

Oh, bad luck. Windows 8 is rather buggy I believe, thats why I'm building my desktop in summer with Windows 7 installed.
I need steps again (1..2..3..).
I reinstalled my video card driver yesterday and no problems so far. Could the video driver been the cause?
Sorry for the delay. First my system went down and I was busy restoring it. Then I spent all last night up with a horse - walking it in circles so it wouldn't founder and die due to colic.
What steps are you looking for?
I've fixed the link to Driver Verifier in my previous post.
Here's the steps that I have. Please excuse the massive number of quotes as I'm way too tired to sort them out!
Driver Verifier:Then, if the above tests pass (and you're able to get into Windows), I'd try these free stress tests:I suggest starting all troubleshooting with the following diagnostic tests (also located at this link: Initial Hardware Diagnostics ). They'll save you a lot of time and heartache if there is a hardware failure, and you'll have the disks on hand in case you need them in the future:
Please start by running these bootable hardware diagnostics:
Memory Diagnostics (read the details at the link)
Hard Drive Diagnostic Procedure (read the details at the link) - Test ALL of the hard drives.
Also, please run one of these free, independent online malware scans to ensure that your current protection hasn't been compromised: Free Online AntiMalware Resources (read the details at the link)
There are also free, bootable antivirus disks at this link: Free Online AntiMalware Resources
Additional free diagnostics here: Additional Hardware Diagnostics
Full list of free diagnostics here: Hardware Diagnostics
I suggest using a temperature monitoring program. I picked this free one because it was the first one I found that also shows GPU temps: CPUID - System & hardware benchmark, monitoring, reporting
I also suggest this one: HWiNFO, HWiNFO32 & HWiNFO64 - Hardware Information and Analysis Tools
What you are looking for:
FurMark download site: FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net
- If you have more than one GPU, select Multi-GPU during setup
- In the Run mode box, select "Stability Test" and "Log GPU Temperature"
Click "Go" to start the test (Looks like it's "BURN-IN test" now)
- Run the test until the GPU temperature maxes out - or until you start having problems (whichever comes first).
NOTE: Set the alarm to go off at 90ºC. Then watch the system from that point on. If the system doesn't display a temperature, watch it constantly and turn it off at the first sign of video problems. DO NOT leave it it unmonitored, it can DAMAGE your video card!!!
If the temperature gets above 100ºC, quit the test - the video card is overheating.
- Click "Quit" to exit
- excessive heat from the GPU (report back with anything over 90ºC)
- problems with the video display (picture is distorted or jumbled, picture turns black, etc)
- problems reported by the program (I haven't seen this, but "just in case")
Prime95 download site: Free Software - GIMPS
- extract the contents of the zip file to a location of your choice
- double click on the executable file
- select "Just stress testing"
- select the "Blend" test. If you've already run MemTest overnight please run the "Small FFTs" test instead. (run all 3 if you find a problem and note how long it takes to error out with each)
- "Number of torture test threads to run" should equal the number of CPU's times 2 (if you're using hyperthreading).
The easiest way to figure this out is to go to Task Manager...Performance tab - and see the number of boxes under CPU Usage History
Then run the test for 6 to 24 hours - or until you get errors (whichever comes first).
Monitor the CPU temperature and DON'T let it exceed 85ºC. If it does, then you probably have a CPU cooling problem.
- CPU temps exceeding 60ºC can cause errors in Prime95. Fix the cooling solution first, then run Prime95 again.
This won't necessarily crash the system - but check the output in the test window for errors.
The Test selection box and the stress.txt file describes what components that the program stresses.

Using Driver Verifier is an iffy proposition. Most times it'll crash and it'll tell you what the driver is. But sometimes it'll crash and won't tell you the driver. Other times it'll crash before you can log in to Windows. If you can't get to Safe Mode, then you'll have to resort to offline editing of the registry to disable Driver Verifier.
1) So, I'd suggest that you first backup your stuff and then make sure you've got access to another computer so you can contact us if problems arise.
2)Then make a System Restore point (so you can restore the system using the Vista/Win7/Win8 Startup Repair feature) - and create a System Repair Disc if you don't have a full installation DVD.
You can do this by going to Start...All Programs...Maintenance...Create a System Repair Disc (don't forget to test the disc to make sure it works).
Creating a System Repair Disk is a bit different in Win8 tho - go to the Start Screen and type "recovery drive" (without the quotes) and select the Settings charm in the right sidebar. Then select/run the "Create a recovery drive" app. Don't insert a USB drive and click the "Next" button. At the bottom left corner of the next screen will be a link that says "Create a System Repair disc with a CD or DVD instead". Click on that and follow the instructions to make a System Repair disc.
For Vista, you can download the repair discs from different websites. If unable to locate them, shoot me a PM and I'll point you to them.
3)Also, to ensure that you can recover, here's another couple of additional steps (doesn't work for Win8):
- Get to the Safe Mode menu (rapidly tap F8 just before the Windows splash screen comes up). Scroll down to and select "Disable automatic restart on System Failure"
In Win8, open the Run dialog (Win Key + R) and type "sysdm.cpl"
Then click on the Advanced tab, then the Startup and Recovery Settings button
Then uncheck the "Automatically restart" radio button.
- Get the RED information from this picture (in particular we will need the name of the file that the error occurred in)
Windows 8 will only have the Symbolic name on that funny looking Blue Screen (I haven't had a chance to post a screen shot of a Windows 8 BSOD yet):
Then, here's the procedure to run Driver Verifier:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "IRP Logging", "Force Pending I/O Requests" and "Low Resource Simulation" and click "Next" ("Special Pool" may be able to be used depending on amount of RAM and errors being seen. In situations with small amounts of RAM, DO NOT select it),
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.
Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).
Reboot into Windows (after the crash) andlocate the memory dump file. If present,turn off Driver Verifier by going back in and selecting "Delete existing settings" on the first page. Then, zip up the memory dump file(s) and upload them with your next post. If no dump files were generated, post back for further suggestions.
If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.
If that doesn't work, post back and we'll have to see about fixing the registry entry off-line:
More info on this at this link: Using Driver Verifier to identify issues with Windows drivers for advanced usersCode:Delete these registry keys to stop Driver Verifier from loading (works in XP, Vista, Win7): HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\VerifyDrivers HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\VerifyDriverLevel

I went on the drivers website and found an update on 18/01/13, I think that might of been a fix for the errors, if I still get them, I'll do the driver verifier and hardware diagnosis.
