Friends,
I have Dell inspiron 1525, with intel dual core processor, 2 gb ram and company loaded vista home basic, which has been updated. Since one when I start my system and try to use any of the appications like ms office, a popup message telling that my ctrl key is pressed even though it is not. After repeated logg off and loggin (not shuting and restarting), iam able to circumvent the problem. I request you all for a possible solution to this. Because of some impt data i donat want to formatt it and reload the os. I have avira antivirus which is uptodate. Please help me.

A few non-destructive checks that complement the hardware possibility raised by and . The goal is to narrow whether Windows/software is falsely reporting a held Ctrl key or the laptop keyboard is physically signalling it.

Start with quick isolation steps: bring up the On-Screen Keyboard (All Programs -> Accessories -> Ease of Access -> On-Screen Keyboard or run osk) and observe whether Ctrl shows as depressed; boot to Safe Mode (F8 at boot) and see if the symptom appears there; attach a known-good USB keyboard and test — if the external keyboard is normal while the laptop keyboard still reports Ctrl held, that points at internal hardware or firmware. Device Manager -> Keyboards -> uninstall the keyboard device and reboot to force Windows to re-detect the driver (non-destructive).

If behavior seems software-related, perform a clean boot (msconfig: hide Microsoft services, disable remaining startup items) to check for an interfering utility or hotkey program. Check for keyboard-hooking utilities or Office add-ins (since the popup happens when using apps). Run an up-to-date full antivirus scan and an on-demand antimalware scan to rule out keylogger/rootkit interference.

If hardware is suspected, run the vendor’s pre-boot diagnostics (Dell’s diagnostics via the boot menu) to confirm keyboard faults. Back up important data before any hardware work. If diagnostics confirm a failing internal keyboard, replacement is the usual remedy; if still under service coverage, avoid opening the chassis.

These steps avoid OS reinstalls and focus on reproducible tests to decide whether to pursue driver/utility fixes or hardware service.

It could be that the membrane under the Control Key is jammed. In the past when I've had a sticky key, a quick punch onto the key frees it. Otherwise prise the key off, (left & right) and with a cloth moistened with spirit (Vodka will do) and clean away any sticky stuff that may be underneath.

Did anything get spilt onto the keyboard?

Agree with Suspishio about the stuck KB membrane part. If the system is in warranty, call Dell and have them replace the keyboard
