PC Details:
Model Mesh Matrix Pro 40GB HD with 256 Mb PC100 SDRAM
Originally running win 98 SE (but successfully upgrded to XP Home on clean
install).

Had no problems until retired it for 12 months to make room for new kit.
Start ing it again for backups and secondary use femoths ago. Still no
problems until I tried to use it with a logitech wireless (infa red) key
board and mouse. It ran OK for first couple of boots, then failed to start
up emitting a beeping noise from rear of case. Similar to when you try to
strat up without having a keyboard attached. Have tried all the simple stuff
like changing batteries, checking connections etc but just cant get it to
boot. Its obviously not recognising the keyboard input as I cant get an
emrgency strau p by pressing F2 keys etc during start up. Have also tried
using the opriginal standard keyboard and mouse without any effect.

Any help to get it back up and running would be greatly appreciated.
