If I unplug my computer for an hour or more, and then plug it back in, it won't boot up if the tuner is plugged in. Anything with an LED, including the tuner, will blink in sync with each other but that's all that happens. If I unplug the tuner, and then try to boot up the system, it boots up normally.
Not sure if this means the tuner is acting as too much of a draw on the PSU for it to boot up correctly or if it's something inherent in the tuner itself. Anyway, just thought I'd make it known.
I've 2 Dell C521s (AMD 3200 and 3800) otherise identical.
Two OnAir Creators connected to the 3200 for a few years - problem free.
When connecting a wireless n adapter, as my fourth always-on USB device, the BIOS would freeze at the 50% mark - nothing to be done except power down and reboot, which always works. My first thought was the NetGear adapter (or its driver), but some time later I reinstalled a clean WinXPHE-SP3 and before installing the NetGear device used a USB memory stick to load some data - it was the fourth device - and the BIOS once again hung.
Some have speculated that it has to do with bootable USB devices - the memory stick or the NetGear adapter might qualify in that regard. Changing the BIOS params to ignore USB bootable devices did indeed have an effect, but it was not a permanent solution.
I have upgraded the BIOS to Dell's latest - for these macines, thats 1.1.10 - and I have repeated this freeze on the sister PC with a fourth USB device, at least one of which is potentially bootable. My Dell systems are more that 3 years old and out of warranty, so Dell could give a hoot whether I have a bug to report or not.
I can get a clean boot every time by unplugging either OnAir device while the other 3 (wireless KB/TP, n adapter, and OnAir Creator) remain connected. This does not imply that the OnAir is at fault - even though unplugging the n adapter also improves the situation, but only by increasing the number of successful boots before failure. Removing all traces of the adapter also cures the problem.
The situation now: all 4 USB devices connected; every other boot freezes.
One and only solution so far discovered: swap the router with the n adapter and hardwire the failing PC. Also, do not plug in a fourth USB device, such as a memeory stick without cleaning the USB tables. I use this http://www.nirsoft.net/utils/usb_devices_view.html
to do so.
It was a plague on scheduled recordings for a while, until I moved the n adapter and reinstalled the OS and apps.
