"Cannot find operating system" on powering up

you could definitely try a restore. Yes it would uninstall the wireless card and whatever else software wise from teh system.

I'd try it, sounds kinda major. Although a wireless card is unlikely to do this. Not the way in which you've expalined, it might be just coincidence it happened near the same time.

I'd also run a harddrive diagnostics. That almost sounds more likely to me.

What type of system do you have? Upon powering up from the "Off" state does the computer give you any "beeps" sound? Does the boot only get so far then tell you there is no operating system OR cannot find drive? Does it give you any options at all?

Ever since my son installed a wireless card and Lynksys router, I get this message on powering up. It takes several attempts to get connected. If I restore back to before the wireless installation, is this likely to solve this issue? Would I then have to reinstall the wireless card and router?
I am worried that one day it won't connect into windows at all. HELP

Using Windows XP Home, get a very brief DELL screen, then screen goes black and the message comes up at the top that it cannot find the operating system. No options given. So, I power it off, wait a few minutes, and power it up again. Sometimes it goes on the 2nd try, sometimes it takes more than that. I am becoming afraid to shut it down, as I'm afraid it won't restart at all. Then I don't know what to do!

No, I know nothing about BIOS, how to find it, what it does, or how to change it. I don't want to make a bad situation worse, so don't want to go tinkering when I have no clue as to what I'm doing.

I am begining to think that your Hard Drive in the computer may be on it's way out! There really is no reason why your system should not be powering up just because your son installed a NIC Card and a router. You may want to browse around these message boards and find one that more specifically deals with your issue. Good luck

unless of course he bumped some cables. I don't know if we're on a desktop or notebook, but i'd have your son doublecheck the cables (assuming it is a notebook) and make sure none are kinda loose.
