Windows 7 Professional x64

Hello zigzag3143,

after a while a new report. I'm not sure if that has something to do with my old problem... while surfing (with Firefox 7.0.1) I noticed that my screen was flickering. It happens when I hover over the windows symbol (the start menu symbol). It doesnt happen everytime I hover over the symbol. I'm not sure what thats all about... if I disable "hardware acceleration" in Firefox it looks like it stops. I tried it with the Explorer and there it happens too. I activated the driver verifier again and it gave me a new BSOD OxA (IRQL_NOT_LESS_OR_EQUAL), I checked it with WhoCrashed and it says it was caused by nvlddmkm.sys... thats the Nvidia Display Driver isnt it? Could the two Problems be related? The 0x4E BSOD and now the OxA? I thought maybe the Motherboard is defect and causing those two problems?

Here the BSOD from the Verifier (the 0xA).

Edit: Now that I think about it I had some issues with my GPU around the same time the BSODs started. I installed the latest (280.26) Nvidia Driver and had some issues with stopping Drivers and Windows recovering from them. Also I think my Monitor went black for a sec and came back again with a recoverd Nvidia driver. After rolling back to 275.33 everything was fine again until now. I checked the Temperaturs and my GPU is running @30C idle and, depending on the load up to ~63C. So I dont think its temperatur related.
