I've got an Atari 1040STE, which was previously working (well, after I blanket-resoldered the PSU - always a notorious spot for dry joints). After leaving it for a while, I came back to find it had locked up with the desktop showing, but not responding to keys or mouse. On rebooting I get a blank white screen - locked, but just blank - and the floppy drive doesn't spin up. Nor do I get keyclicks when I press the keys. What could I look at first? With the ST come up with the keyboard unplugged, or will it just sit there in silence? Gordon
