Intermittent BSOD, Bad Pool Caller/Header, Pretty sure it's a Driver

If I understand correctly what you are describing, it sounds like a classic Graphics Card dying. But just to be sure, I would like to try one other thing.

I am going to give you some links that will help you get a good clean install and not have any drivers you don't need that will conflict with other drivers. Download a WHQL driver from https://www.sevenforums.com/graphic-c...ndows-7-a.html . Once you have them downloaded, uninstall you current driver from control panel. next clean up any left over drivers from following this tutorial Drivers - Clean Left over Files after Uninstalling and select only ATI Display Drivers. After you have done that and rebooted, install the new driver, only select custom install and install only what you have to. Very few people need most of what they include. You do not need the audio/HDMI drivers as you already have that in your Motherboard drivers. Unless there is some reason you need them, the only thing you really need is the Display Driver.

Please use a utility that will monitor your GOU temps. If they get too high, stop the test I am going to get you to run. Most of these utilities also allow you to set a custom fan profile. Set a pretty aggressive custom fan profile, to control your temps.

Please download and install Ungine Heaven 4.0 ( Heaven Benchmark | Unigine: real-time 3D engine (game, simulation, visualization and VR) ) install it and run the test. Set it to the extreme preset and run it. Once it starts to run, press the Benchmark tab at the top of the screen. Let it run, keeping an eye on the temps as well as looking for any artifacts. The benchmark is strictly a GPU bound test, meaning it uses nothing but your graphics card. If the temps go too high, stop the test. Your set up should look like this.

Try this and let me know how it comes out. It will give your card a pretty hard workout, so again, pay close attention to the temps. If you do not have a Monitoring program use MSI Afterburner (MSI Afterburner). With this it will allow for on screen display and custom fan profile. It is primarily an overclocking utility, so don't move any of the sliders on the first page, click settings and there is a monitoring tab, and a fan profile tab. Use those, it is a very good monitoring program and can be used to set a number of profiles. If your card is overclocked, please set it to defaults. Please let me know how this works out. let me know the high temps as well as if you noticed any artifacting. If you have any questions, don't hesitate to ask.

Let us know if you have any more BSODs. We will look at the new dump files.

Thank you for the kind words. That's what we do here. But before thanking me too much, it looks like I haven't helped much. Here is what the dump file says, for what it's worth

Which actually tells us very little. I did notice some references to USBport. Which is usually a Windows Update driver. Please update your Chipset Drivers again and lets Please update your system specs as much as possible, with manufacturer and Model, plus hard drive info, PSU, CPU cooler and anything else. I am going to give you the post I usually use. You have much of yours filled out, so it should be fairly easy, but hopefully, this will help you know what I want. Basically what I want is everything in your, or attached to your computer with model numbers to enable me to look the item up if necessary and I would like it in your system specs at the bottom left of your last post.

Please fill out your System Specs

   Information

Your System Specs will help us to help you, and doing it in this manner will make them available to all helpers in every post and keep us from hunting for them. We ask that you fill them out in as much detail as possible including Desktop or Laptop, Model number if it is an OEM computer and all components with the Manufacturer and Model number if possible.

If you will go to your last post and click the 'System Specs' in the bottom left of the post, you will find a link to update your system specs. Please fill those out in as much detail as possible, making sure to click save at the bottom of the page. If you would like to know what we would like, you can click 'My System Specs' at the bottom left of this post to see mine. If you do not know what your components are, this will help you accomplish this task. System Info - See Your System Specs

Once we get that I am going to want you to run a Hard Drive diagnostic test on your hard drive and maybe even memtest86+ which will take you between 9-10 hours. But first I would like to get details of your system specs. Also, do you have a spare graphics card or have a friend who would be willing to loan you one for a few days, or better still swap with you? We won't go there right now, but you may start asking around.

I will always try to beg, borrow or whatever is needed to test before asking you to spend money. That's what I would do, and I won't ask you to do anything I wouldn't do. The big difference is I have more computer parts around than some computer stores.

If a known good card is used and does the same thing, it has to be the Motherboard or the PSU. Those are about the only things involved other than drivers. If you change cards, clean all drivers from the system before swapping.
