3-month old 7750 Graphics Card -GSOD/buzzing with 3d video/gaming
For the past few months I've been plagued with video problems...
In July, RIGHT AFTER my warranty expired with dell my 4850 HD died.
I bought a 7750 HD XFX and was quite happy for about a month. Made sure I driver-sweeped the old drivers and kept the catalyst/drivers up to date and have been left with a 95% EXCELLENT quality of video AND 5% GREY SCREEN OF DEATH/BUZZING problem.
It also has problems switching audio when I switch from my monitor to flatscreen with HDMI. It occasionally detects the audio easily when i hit "windows key" + p and occasionally will not. I recently got an error saying something to the effect that my HDMI output wasn't working correctly and haven't been able to reproduce that error. However, I did sweep my Realtek audio drivers, installed new ones, updated my chipset (which I just realized needed updating tonight), and I still got a GSOD. I have pictures and video, but am unsure how to upload easily to this forum.
My GPU passes all stress tests (Furmark, etc.), all dell PC dr. hardware tests, and I have the Ultimate Boot Cd and tried running some memory tests... no problems so far...
Like I said for the most part I am very happy with my machine, except the GSOD which rears its head about 1/3 of the time I watch a movie using VLC, WMP or Netflix/Hulu or whatever online flash based player. It does not necessarily happen when the GPU heats up or works for a while.
It ALWAYS freezes when I do certain things like walk in areas with high smoke/fog rendering in Skyrim. It ALWAYS seems to involve audio and video.
Any and all help would be *GREATLY appreciated*!
Thanks-- I'll try to provide as much info as I can if I left anything important out...
