Hi everyone I have some strange issue that I grew tired of in the last few weeks and I hope you can help me fix it. I recently bought a Force3D 5870 (reference design and clocks) with FSP Epsilon 800w PSU to upgrade my system (see the specs below), installed a fresh copy of windows7 x64 and CCC 10.3, then I started to encounter some strange issue...Sometimes after restarting windows, I see only part of my desktop (~30%) displayed in the middle of my primary monitor (BenQ T2200HD) as a square area and the rest of the screen forming a black frame. When I open CCC and rotate the desktop into portrait mode and then back to landscape, everything will be shown, but the card will stick to 2D clocks and won't go to 3D mode even in games and Furmark!! I also noticed that when this happens, CCC forgets all my settings and resets them to default..After that if I restart the PC, everything will be OK, but if I shut it down, leave it for a minute and then start it again, the issue re-appears. So far I tried the following to no avail: 1-Disconnecting my secondary monitor (BenQ FP72E) and reconnecting my primary one to the other DVI port 2-Using HDMI to connect to my primary display. 3-Uninstalling and updating my monitors drivers 4-Uninstalling CCC, using Driver Sweeper in safe mode and then installing 10.4 and then 10.4a 5-Changing Scaling options in CCC . Also saving and activating a CCC profile in the hope it keeps my settings and also to raise 2D clocks 6-Updating my mobo's (P5KSE) bios and playing around in its settings. 7-Changing the PSU cables feeding the GFX card then changing the whole PSU to FSP 500w 8-Removing my CPU and RAM overcolck. Nothing of the above helped, and the issue persisted, so I tried some other things: 9-Using other cards in my system (HD4870-8800GT). The issue didn't appear. 10-Using my card (5870) in my nieces' system (E8400+DFI Lanparty DK-P45 Plus) and the issue didn't appear as well, even when I used my PSU and Ram in their system !! 11-I thought it might be a software conflict, so I did a fresh windows vista 64bit installation, with nothing installed but the CCC 10.4a, and the issue appeared after the first shut-down-startup attempt !! 12-I reverted to the drivers that came with the card (on disc) after driver sweeping and all hell broke loose! Lockups, Orange screens and then 'display driver stopped responding and recovered' messege! Pleaaaaaase help! What must I do? Is this a faulty card? Or just a software issue? Should I RMA? Any input will be appreciated ! My full specs: E6750 @ 3.6Ghz, ASUS P5KSE, OCZ reapers DDR2 @ 1081Mhz, WDC Green 1TB, Maxtor 160GB, Force3D ATI Radeon HD5870 (stock clocks), FSP Epsilon 800w, Antec 902, BenQ T2200HD (Primary), BenQ FP72E (Secondary).
