I just had some problems under Windows 7 32bit and I can't find a solution. Here a list of symptoms and possible causes that I doubt: Symptoms
In the processes page of Task manager, the quantity of memory used by a process is not displayed, while that of the CPU is displayed as usual. The processes can still be sorted by memory occupation.
From the right click menu, I can create nothing but a new folder in c:\. And in partitions of my portable HDD, the same thing happens in root directories and SOME OF the sub folders which are CREATED (not modified) after 1st Oct.
Windows cannot show hidden files even after I changed the settings in the Registry(and in options). If I create a file and set it hidden, it will disappear in less than 1 second. I roughly checked all partitions with winrar, but nothing suspicious(like autorun.inf, ****.exe) has been found. Possible Causes
I just installed a usb Bluetooth adapter.
Letters of my portable HDD (which were fixed for months) have been changed since I inserted an other portable HDD earlier today. I was not able to undo it.
Virus or something, but I'm not quite sure. I found nothing unusual in start-up programs and running processes. My avast home edition detected nothing.
Please could someone help me?
