Hi everyone, I'm NEW here and I hope I don't sound like a complete idiot or post in the wrong place    I'm suddenly having trouble with what I'm assuming is my graphics card.  I've had OBLIVION installed on here for about two months now, never had any problems with it.  Now, whenever I try to play, Windows encounters a problem and needs to close.  Similarly, whenever I try to play any games on Steam, it refuses to go into full screen mode.  Also, this has never happened before now but now whenever I load Oblivion, Windows has to go into "basic" view mode and it can't display my Aero theme and run Oblivion at the same time.  This has only started happening today.

As far as I know, I haven't modified any of the settings.  I'm not completely ILLITERATE but my knowledge is limited when it comes to graphics cards etc.  All I did today was uninstall Norton Anti-Virus Suite so I could reinstall it from Comcast (since it's free from them).  I didn't uninstall anything else that I recall.  I'm really confused as to why my computer is doing this all of the sudden....Oblivion ran fine about two-three days ago 

I am running Windows 7 64 bit, with 4GB of RAM and the graphics card is ATI Mobility Radeon HD 4200, the processor is AMD Turion

Something I did notice... when I went into the settings in Oblivion it has my graphics card listed as AMD M880G with ATI Mobility Radeon HD 4200.  I don't remember this being there before.

I attached a screen shot portion of my specs from "Can You Run It?" for Call of Duty: World at War

[recovering disk space - old attachment deleted by admin]Maybe try a System Restore by doing the following> Press Start /Accessories/System Restore. Now choose a date just before all this went wrong and press ok. You may have to Boot into safe mode to do it.Seems like the computer is using the onboard video card. Check the BIOS settings to confirm this. Quote from: JoshM on October 31, 2010, 01:14:26 AM
