Hey, Im using Windows 7 Build 7229. Its all fine except this problem. My pc- HP G60- 115EM has a built in card-slot. I use my sd card with it. The sd card works fine. But every so often it decides to go wrong. When i go to "Computer" and select SD Card it takes ages to load. Then after it will freeze explorer. Then when i shut down the computer it will idle at logging off so i have to do a hard shut-down. This has happened lots of times. I have no yellow flags in the device manager and my card slot driver is up to date. Please help. This is annoying since i use my sd card alot. And this dosent happen in Vista.
