Yes engineer they need your specs. I had a similar thing happen to my laptop. An Acer Aspire 3000 and I/We were able to work through it and get the right driver for the wireless and then things are back to operating normally.
Please have patience with us. I know how frustrating it is. But it can be resolved. we just need information to help you. You should be able to load the usb or cd that you used to install, its called the live cd. If your system will boot up with that, then I am sure they/we can help you.
Don't give up on us yet please.
