It was the driver to cloud client rushfiles. But I restored windows to the state it was in when it came back from acer customer service anyway as regedit search wasn't working properly either. I used all the drivers from the acer site. Then I ran verifier again and this time it didn't ike the card reader's driver. I disabled the card reader and now it just crashes without telling me which driver is wrong. Could you have another look, please? P.S.: Yey, file upload is working again!
