I can't believe it... I have to ask for help... (swallows troubleshooting pride)
Lately, and with increasing frequency, my G4 tower has been acting up- the mouse will freeze, but the keyboard will work and it seems that the computer is still running just fine. Or both won't work. Or the display won't wake up from sleep. Resetting seems to be the only way out of these situations. But this afternoon both were nonfunctioning at the sign-on screen, and it only worked after unplugging (I couldn't get it to turn off). My first instinct is to swap keyboards, but I don't have one and I don't want to buy one unless it seems a likely culprit. The keyboard is Apple, the small one that came with the original hockey puck mouse. The mouse is relatively new, third party. At first it seemed like plugging the mouse directly into its own USB port instead of through the keyboard helped, but then it went back to doing it. And sometimes the mouse will just hang, then go, then hang, then go, then back to normal.
Thoughts? Keyboard? Do USB ports just go bad (all at the same time?) My thinking is hardware, but could it be something else?
This is a hacked tower, to run quietly, so it probably has experienced higher temps than a normal tower. But it made it just fine throught the summer, and it's been on the cool side lately. And I'm not getting sudden system-wide lock ups that I usually associate with overheating.
