Hi, First post, i've been searhing ggogle and these forum posts but have not found anything related. I used to use XP pro Sp3 with a microsoft USB wireless multimedia keyboard and mouse and never had any problem with it on my desktop. On a brand new HDD, i installed WIN7 32-bit ultimate and successfully activated with Daz's loader. (same PC, new HDD) I still use the same keyboard and mouse and have installed the latest intellipoint software and checked microsoft drivers are the latest. i have also checked my power saving profile, particularly with regards to USB ports. My problem is that every now and then (maybe 5 mins , maybe 5 hrs) the keyboard seems to go to sleep, (although the multi-media keys still work). Pressing the alphabetical keys often starts opening settings menus in IE8 for example or other weird events / windows. At the same time as this occurance, my mouse works (sort of) but if i click the left button on a folder it will open the "properties" instead of opening the folder. To "re-awaken" the keyboard and correct the mouse functions I have learnt that if i press "control" and "ALT" together, everything comes back to normal. Can anyone shed any light on this. I am concerned it might be malware (like a keylogger or something) but i have Kapersky 2010 and have run spybot S&D, windows defender, malwarebytes. Maybe i'm paranoid on that point and im chasing the wrong direction. The last thing i tried was having a PS2 mouse plugged in at the same time. When things went messed up i though maybe the PS2 mouse would function normally, but it went messed up just like the wireless one that was still connected. Considering this was all fine under XP, i don't think i need a new keyboard and mouse.
