• CPU - Phenom II quad core
  • GPU - R7950 HD
  • RAM - 8GB
  • SSD - 2x120GB RAID 0
  • OS - Windows 7

Install Environment

  • Up-to-date windows
  • Latest beta catalyst drivers
  • Up-to-date game cache
  • No Mods
  • Other software runs fine (unlikely to be RAM)
  • Mouse trails disabled

I have New Vegas (installed through steam), it's been running fine since its install half a year ago.

I was playing a save yesterday, and after a couple of hours I encountered something that seemed like a memory problem (glitchy, shaky movement, clipping issues), which led to a CTD after several minutes. I tried playing again today, and on passing the intro screens, I had no mouse cursor, and seemingly no keyboard input.

Edit: I was able to get into one of my saves using the arrow keys (should have thought of that). I have no mouse input in game period, or keyboard input (aside from dpad and return)

Edit 2 Going into the settings, there are no mouse or keyboard options period. Time for a complete reinstall of the game :( - the ESC key works for skipping the intro sequence, but no further.

Steps Taken

  • Restarted PC, jiggled the cable
  • I had an older catalyst driver, I updated to the latest beta (don't think this matters though)
  • Verified the integrity of the game cache
  • Deleted and allowed the game to re-create the .ini settings
  • Searched for 3 or 4 pages and found no similar issues
  • Try doing system restore or file restore to an earlier date that the mouse was there, back up your save file before you do this.

  • @Wojtek'Charkz'Hordyniec I would NOT recommend this. He only has problems with his game, not the entire pc.

  • I gave him two options, file restore or system restore. It could very be some mod, or something he installed that is causing the problem or a dodgy graphics card update but not in his case. It has fixed problems before for my friends when I done it. System restore is a save procedure if you know what your doing and back up anything important.

Welp. My logitech controller driver changed in some way, or some kind of .ini thing happened, and new vegas decided to prefer it preferentially over everything. I saw controller mappings in the settings menu, unplugged it, and got mouse/keyboard input back. Plugging the controller in again cause the game to point out an option to disable 360 controllers, which I never paid attention to because I don't have a 360 controller (yeah yeah, 360 mode), and because this has never been an issue. I was about to reinstall when I noticed the button mappings in settings.

Thanks for your input VascovdEng and Wojtek. Sorry if I wasted anyone's time, hopefully anyone else with this issue will see this.

  • Solution: Unplug your gamepad.

Hmm, upon googling your problem I came across this as the first link, this could be your answer, also go into your graphics options and disable 'Hardware Mouse Cursor" if the game has that option a lot of games do.

From Steam support

  • Please disable pointer trails for your mouse Start > Control Panel > Mouse > Pointer Options tab Uncheck the Display pointer trails box If you are using Windows 7, make sure the Magnifier is disabled: Start > All Programs > Accessories > Ease of Access > Ease of Access Center Click on Make the computer easier to see Uncheck the Turn on Magnifier box and click OK
  • I already have mouse trails off (in general, not as a step) - Nothing about my computer has changed other than the crash itself. Thanks though. Commented Oct 24, 2013 at 11:12

    Right, I know my friend had a problem with another steam game, and weirdly it just came back after a day or two, could be a steam glitch, maybe your best bet would be to contact them. After googling it. It seems there isn't anything that is a straight fix just theories.

  • Thanks for taking a look into it further, if this doesn't turn out to be a known issue I'll probably try a full re-install of the game(really not looking forward to that) Commented Oct 24, 2013 at 11:20
  • That could fix the problem, do you run any mods?

  • As I said in my OP, no mods. I managed to get into a save, no keyboard or mouse input at all (details edited into OP) Commented Oct 24, 2013 at 11:30

I had the same problem, but in my case, it turned out that the xbox controller (or any another controller) plugged into my PC leads to this strange cursor/enter/backspace problem. So check that you don´t have any another control devices connected at the same time.


Go into control settings and turn off 360 controller. Worked for me.
