I bought a wireless USB keyboard & mouse & tried to instal today.The mouse worked OK but the keyboard was dead so i removed it intending to return to the store tonight.I fitted the old PS/2 keyboard & mouse but they now they won't work.
I don't know how to gain access to the bios as i have no input atall.I presume the drivers of the wireless one altered it.I tried the wireless mouse again but it's stopped working.I'm stuck as all i can do is turn the computer on & off at the switch.
The wireless unit wouldn't normally access the bios ... They would override the standard drivers installed into windows ...normal advice would be to boot into safe mode and use the basic drivers there but with no input at all this becomes rather more difficult.
Possibly switching the machine off while windows is runnning and then switching back on you may initiate the "windows was shut down prematurely" procedure and boot you into safe mode and give you keyboard and mouse access for a short time... only recommended if desperate !!
Earlier tonight i put the hard drive in another machine & formatted it & then put it back in the original computer.I intended to reinstall windows but k/b & mouse still not working so the bios must have been altered. I'm afraid it's looking like a new m/b as i can't get in to the bios.
When you removed or replaced any of the ps2 connections, did you ensure that the power was turned off, they are not hot-swapable and pluging/unpluging with the power on can blow a fuse on the mobo which is usually non-replacable.
I have a boot disk & i tried it but nothing.I always shutdown when taking out or replacing Ps/2 cables not that i do it often.It was an unsual way of installing that wireless stuff as you had to have it up & running before the software was installed.
