Hello, need some help with recent BSOD related PC crashes. I've recently added new hardware to my computer, at first I only installed a new GPU (R7770 PMD1GD5, MSI). I installed the drivers and everything was fine. Then I installed a new Motherboard, CPU and Sound Card. Again I installed drivers but then I got some BSODs. Figured I might aswell do a format and reinstall Windows 7 x64 and drivers but the problems did not go away. (I'm also using a 75W 6-Pin PCI Express power connector between my new GPU and the PSU.) Sometimes when the computer crashes there's no BSOD it just freezes. I've gotten only 2 different BSOD IDs (0x00000ea and 0x00000116, first one says "THREAD_STUCK_IN_DEVICE_DRIVER the second one doesn't have any Bug check string). So far the BSODs have not happened when the computer was idle but it can happen when I play games, using Google Chrome or just about anything). I've tried installing my old GPU (NVIDIA GeForce 9600 GT) and drivers of course. While using the old GPU there's no more PC crashes which leads me to think I've isolated the issue to the new GPU and probably the drivers for it. For the new GPU (R7770 PMD1GD5) I'm using the driver software found here: http://www.msi.com/product/vga/R7770-PMD1GD5.html#/?div=Driver&os=Win7 64 (was using the same drivers with my older Motherboard + CPU with no crashes) New GPU requirements state that a 500W PSU is recommended.
