PC Wont Boot & Keyboard Wont Work

Evening All

My computer must have realised I was looking up component parts to build a new PC because it seems to have gone off in a huff and stopped working.

I was doing some photo editing in Adobe Bridge, it froze, so I rebooted. When I rebooted, I decided to install a copy of Lightroom that I had because Bridge had frozen a couple of times lately. Anyway, during the install process, my PC made the beep that it normally makes during boot up, then it flickered and restarted itself. When it got to the screen that gives you the option to begin in Safe Mode, I couldn't because my keyboard had stopped working. When it timed out and tried to open normally, a blue screen flashed (I couldn't read what it said) and it rebooted. I've tried Del and checked the settings in there, but don't really know what I'm looking for, but the keyboard let me move around in the menus. Came out of there and the keyboard wouldn't work at the Safe Mode screen again. Rebooted again, this time, tried F9 which is the Xpress Recovery menu, but again, the keyboard wouldn't let me do anything. Although, not sure I wanted to choose anything from that menu anyway.

I've had similar issues happen in the past, but have always been able to access windows in safe mode and use a restore point.

I've searched for variations of this problem on here, but there's so many different situations I thought I'd just post again. Apologies if I've missed the answer somewhere else.

Would appreciate any help or shoving in the right direction. My laptop doesn't have any of the software that I use for my photo editing. Typical this happens just as I'm ready to put together my offline system specifically for photo editing! Meh.

are you useing a wireless keyboard ? if so replace this with a normal wired keyboard. that should allow you keyboard use and then you can get to safe mode or try last working mode

nope, just a normal wired keyboard.

Ok, I managed to get the keyboard working by going into the CMOS settings during bootup and changed the USB keyboard to enabled. Now I've got into Windows XP in safe mode, but it's saying that System Restore has been turned off by group policy and to turn it on I need to contact my domain administrator!

Is there anything else I can do now I'm in safe mode?

in the start menu click run then type in cmd and click enter when the comand prompt opens type in chkdsk c: /r and press enter once finished reset and see if your computer loads normaly.

Hello friend, I think it might be due to the boot error or error in loading boot file. In my point of view it may be possible that your windows has been corrupted either due to the viruses or spyware programs.So you should reinstalled a fresh copy of windows.

okay. i ran a scan with my anti virus software and it detected a load of new ones since i last did a scan about a week ago. i had it repair them all and rebooted. it didnt give me the option to go into safe mode now, it gave me a message on a black screen saying:

"Windows could not start because the following file is missing or corrupt:


It says that it can attempt to repair it by starting Windows Setup on the original CD-ROM, which I don't have any more because a guy my uncle knows built me the original machine about 6 years ago and I never got any discs.

Is there any way I can repair this file without Windows Setup?

DO you have a floppy drive?

  MrSheen 13:23 29 Sep 2009

Yep I have a floppy drive. No disks for it though. Also, at no point can I get a command prompt to try the commands in the linked thread.

Am going to see if I can find the file using my laptop and try and copy it to CD and give that a go.
