The dump points out memory corruption. All of your drivers seem to be up to date. Let's test your RAM to make sure it is not the problem. Follow the instructions in this tutorial: RAM - Test with Memtest86+. Errors, if any, will show in red on your screen. Post your results.

If you do not get any RAM errors, enable Driver Verifier following the instructions in this tutorial: Driver Verifier - Enable and Disable. Use your computer normally while Driver Veririfier is running. Upload any dumps triggered by Driver Verifier.

If you have any questions, please ask.

Upload the BSOD. Driver Verifier will create a BSOD every time it finds a faulty driver. That is what it is supposed to do. Unfortunately, the dump you uploaded does not point to a specific driver even though it is a Driver Verifier enabled dump.

Edited to add: Since this BSOD happened during startup, that tends to indicate a hardware problem. Do you have access to another power supply unit you can try? A failing PSU can cause problems at startup.

Do you have a computer store where you can buy one and return it if it is not the power supply causing the problem?
