Good morning guys , i' ve just bought a new gaming rig few days ago with this spec:

VGA Club3D RoyalKing Ati AMD Radeon HD 7850 Core 910MHz Memory GDDR5 4800MHz 2GB DVI HDMI

motherboard : Asus Sabertooth 990FX R2.0 Socket AM3+ DDR3 SATA3 USB3

CPU AMD FX-8350 8-Core Vishera 4.0GHz Socket AM3+ 16MB 125W Boxed

RAM DDR3 Corsair Vengeance Red CMZ16GX3M2A1866C10R 16GB (2x8GB) 1866MHz PC3-15000 CL10 10-11-10-30 XMP 1.5V Retail

Power suppy : PC XFX ProSeries 550W Core Edition

monitor : an old benq FP71G+ with a DVI-CRT adapter to the graphic card

Ok now i got 2 main problem :

1)since the BIOS init i got slighty vertical stripes on my screen
(But my monitor is ok i test it with another PC and no stripes maybe graphic card/monitor incompatibility)

2)the main problem , i installed windows 7 64 bit and everything went fine
> reset installed Mobo drivers
>reset installed graphic card drivers here
http://support.amd.com/us/gpudownload/windows/Pages/radeonaiw_vista64.aspx
(i tryed both fisrt current then beta drivers)
>reset , loading windows screen and suddenly just before when the cursor normally appear i've got a black screen (but the monitor dont lose the signal) with no further loading because i cant hear the normal login sound that i have when graphic card is disabled .
>Safe mode boot and normal boot with graphic card disabled works fine.

The graphic card is broken or something ?
Is it possible that DVI-CRT adapter or monitor are causing the crash ?

Thx for your time and patience .

I'm new here, and I just wanna try to help. So please, be easy, lol.

Is it possible in resetting your MoBo, and redoing all drivers, that your on-board GFX is conflicting with your 7850? I learned that they have a tendancy to do so. Maybe you forgot to re-disable it your BIOS.

Hope this helped. I tried, lmao.
