I'm working with a HP Pavilion P7-1414 running Windows 8.1. The computer currently has a Ralink RT5390 wireless card that comes with the computer.
After you connect it to wifi and start browsing, the machine will either bluescreen or freeze. If it bluescreens, according to the program "whocrashed" it's a DPC Watchdog Violation error and has been referencing two different system files: hal.dll and ntoskrnl.exe. I have installed a brand new Startech PciE 300n adapter (PN: PEX300WN2X2) and discovered that is also uses Ralink drivers, and will also bluescreen or freeze the pc after connecting to wifi and browsing. I have tried about three different versions of Ralink drivers on both devices and all will result in failure.
Here's the curveball, I have a USB realtek wifi dongle that I installed, confirmed it was using Realtek drivers, and it is NOT crashing or bluescreening the computer after a couple hours of testing.
Any suggestions as to what's going on? Is it underlying ralink driver corruption or perhaps a registry issue? Issue just started happening on Monday the 15th, and the customer suspected it might have been a Windows Update. I checked the update history and saw where there was an attempt to upgrade the Ralink Driver a few days prior to monday, but reports failed. Don't see any other updates that could be affecting it.
