Often when I put my Windows 7 [64 Bit] PC to sleep and then wake it up, my log-in screen changes size. After i hit Ctrl+Alt+Del and log-in, my Desktop has huge Icons and the open windows are so big that they take all of my screen size. I have to wait for like 10~20 seconds before the monitor automatically brings back the original size/resolution. The problem is that i have lot of programs/icons on my Desktop and every time this happens some of my icons get moved to some other place on my Desktop so i need to bring them back manually to their original place. This problem does not occur every time after i wake-up my PC, but quite often. Has someone similar experience ? Does someone know a solution to this ?
My graphic card is NVIDIA GeForce GT 545. And my monitor is Dell U2412M [24 LCD]. I have updated my graphic card and the problem remains.
