I am looking at the XP Pro SP3 machine (HP-branded) at the moment and noticed that, when booting, you could load happily onto the desktop. But when you move the mouse cursor to the anywhere on the taskbar, the cursor changes from an arrow to an hourglass. I hit the windows key on the keyboard but found that nothing happened. No menu appears when I right-click my mouse, no matter where on the screen I do it. CTRL+ALT+DEL do NOT call up the Task Manager.
It doesn't happen all the time, but most of the time.
I ran a repair reinstall of Windows, having to roll it back to SP2 as a result and then bring it up-to-date via Windows updates. The issue still occurs. It does not happen in Safe mode, nor safe mode with networking (that I can recall). I have tried turning things off systematically in MSCONFIG, but this doesn't seem to have produced the results I was hoping (windows explorer crashing, essentially, from what I can gather).
I've run a memtest in case it was some whacky RAM issue and have also run chkdsk /r with no change. The customer is running uniblue software (bloatware) and is adamant that I leave it on... is it possible that this is causing the problem?
Have run NOD32 & MBAM thorough scans which both show clean.
Thoughts? What would be causing explorer to crash, if that's what it is?
What could be cause?
