I'm running XP SP3 fully updated. For the most part it runs OK, however, it frequently starts opening and closing various menus, dialogue boxes, the Start Menu, context menus, opens programs, closes programs all by itself, quite often this opening and closing is of menus etc. that I've recently opened deliberately.
With the exception of the Start menu, the items that appear will be scattered across the screen. This opening and closing happens very rapidly but will slow to a stop providing, that is, I don't use the mouse or keyboard. If I use the mouse or keyboard while the opening and closing is happening it will continue and not slow or come to a stop. If, once this opening and closing has slowed and stopped, I try to use the mouse or keyboard it will start again and basically the PC becomes uncontrollable. Anything I click does not open or start. The problem seems to be associated with holding the Ctrl key down whilst using other keys or the mouse,
occasionally the same happens when holding the Shift key down.
The only way I can regain control of the PC is to press Ctrl + Alt + Del to bring up the Windows Task Manager. Once the Task Manager has started I only need to shut it down again to regain control, however, even this sometimes does not work and then my only option is to power down with the on/off switch and cold reboot. The PC has had this problem for some while but I have been unable to find a solution.
In an effort to establish if the problem is hardware related I've unplugged the expansion cards, changed expansion cards, swapped memory modules over, changed memory modules, disconnected all drives except the 'C' drive, removed and refitted the CPU.
The PC was recently infected with malware of some kind, despite using the latest and updated Sophos AV, however, this infection was within the last couple of weeks and I don't think the two are related unless the original problem enabled the infection to occur. Hopefully I have removed this malware by using Malwarebytes and ComboFix.
I have uninsulated all trialware and some other programs that I don't or am unlikely to use and then ran CrapCleaner to clean up afterwards.
The Windows Event log does not show any problem that I can Identify.
I know I could reinstall the OS but I would prefer to find and fix the problem if possible. Any assistance in solving this would be be much appreciated.
