crash now no wi fi

hi guys hope someone can help with this big prob for me, i had a power failure which according to the event log was critical and when it powered up again i have no wi fi in the device manager there is no wi fi hardware its disappeared, i tried system restore but it flags up there are no restore points i have tried to restore in safe mode with the same response, it would be difficult for me to use a cable so hopefully someone will have a fix for me, thanks, steve

Load defaults in BIOS (either first screen or exit menu), it is the setup menu when you first start the PC.

Boot with a Linux Mint MATE DVD/USB and see if it works there, report back.

hi, thanks for your reply, i'm not sure exactly what you are telling me to do , i have opened bios setup utililty and scrolled to load default settings, load optimised defaults yes, now what is linux mint mate and where do i get it, thanks, steve

Save and exit after loading optimized defaults then if it doesn't correct the issue:

See Emergency Kit - save your files from a dead OS

Don't get confused by the name of tutorial, you will only use it to see if adapter is working with it. After making the bootable USB just boot with it, no install required.

hi,while waiting for a reply i have been looking at other forum posts although not identicle probs to mine and havefound how to see hidden hardware and have found wi fi adaptors but when looked at show not connected code 45 to fix reconnect to to computer, could this be my prob? if so how do l reconnect these items, thanks, steve

hi, thanks for that have read thro it and now waiting for a big enough flash drive to come will get back to you with result when done, thanks again

Good luck :)

hi, loaded up mint mate same prob no wi fi, its not showing any available connections, also the icon on my pc in win7 is different now for no wi fi where it used to be the five bars with a cross its now a sort of wire with a cross, getting a bit nervous now, thanks, steve

hi, since my last post i have tried something else which should perhaps shed more light on my prob for those who know about win7 [hopefully anyway] i came across a wifi dongle which i installed but with no luck so i installed it on another pc also running win7 with success this time so uninstalled and reinstalled with the intention of replicating each move with the dud machine to see where the breakdown was occurring loaded cd clicked on setup checked a few boxes and it loaded up on completion checked devices and there it was done the same with the dud machine same sort of thing but on completion checked devices no adaptor so is it swimming around somewhere on the pc or what hope this highlights my prob a bit, thanks for any help

Got a restore point prior to the power failure?
If you have, try that, and if it still doesn't work, in Device manager are thier any unknown devices.
