No Memory Cards Working

The problem is that no kinds of storage cards are currently working perfect on my computer.For an example no phones can be connected, have tryed 2 htc's with microsd cards, and a sony ericson with an m2 card, and same problem. Also if i try to open any SD cards, like camera it dosent work.The thing is that it comes up as removable drive, but when i try to open it it just says please insert card. I have tryed deleting, installing reformatting drivers, and cards like crazy and its the same. I have also tryed changing the drive letters around but the issue is the same.The only thing that makes the work is the following: If i leave the card in the cardreader, or a phone connected, then restarts the pc whitout removing the card or phone, then it works when its rebooted. but asoon as i remove the card/phone and reinsert them the issue is still there "please insert card".I have even changed the motherboard, cpu, and memory, and formated the computer 3 times but still same issue. So im thinking that windows is installing wrong driver or something? [code] Also the issue was the same on my old computer also running windows 7 that had a socket 775 build.
