This page is for technical problems with Skyrim (e.g., video cards, system software issues). It also lists probable causes and possible workarounds and solutions. For problems with game logic, see Glitches. If you need information on whether or not your PC should be able to run Skyrim, please see System Requirements.
 Crash Types
- The system freezes (i.e. all programs stop) the screen may go black and a reboot is required.
- The game crashes and displays an error message detailing the crash.
- The game crashes and abnormally exits to the desktop.
- The system reboots itself unexpectedly.
- The game screen freezes and the audio goes into a continuous loop. After some time the game may resume. Alt-Tab still allows selection between applications if another one, like Windows Task Manager, is running.
 Possible Causes
 Memory Shortage
You may not have enough system RAM or video RAM.
- The obvious solution is to buy more RAM or upgrade your video card.
- Disable high-def textures if you have less than 4 Gig system RAM or 1 Gig video RAM.
One possible cause you should eliminate is overheating. Here are some general suggestions that might help regardless of the chip set or a particular computer's configuration out of the myriad of possibilities.
- Clean Up: Dust acts as an insulator, like very fine downy feathers, holding in the heat and allowing it to build up. Remove the cover on your computer. Use a soft brush attachment on a vacuum cleaner and gently vacuum the interior. Then if you have an air compressor, a shop vac or just a can of compressed air, blow out the interior. You will be amazed at the dust the vacuum did not find. In fact it is not a bad idea to wear a little dust mask or do this outside.
- Clear Out: Remove papers, books, etc. from air intakes and outlets. Make certain your computer is in an area with a supply of fresh cool air, not in a small cabinet.
- Adjust Down: If the GPU overheats, it may drop out of high performance mode. If it does so, the work will be picked up by the CPU(s) on the mother board. Their temperature will climb. There is no graceful drop out, just a messy crash or hang. Run Windows Task Manager and look at the Performance tab to check on the CPU(s). You really want to average under the fifty percent mark to insure stability. Most GPU's come with some kind of software control package, so run that package (e.g. Catalyst Control Center):
- Check the cooling fan settings. Often fans are defaulted to a low and quiet rpm which is adequate for spreadsheets, word processing and surfing the internet but is not sufficient to keep the GPU cool when playing a demanding game, like Skyrim. You want all of the cooling you can get.
- Make certain the overclocking, if selected, is modest - say +40% of what is possible. You can adjust up or down later. The key here is to check your GPU temperature. If you can keep it around body temperature (37 to 41 degrees C) that is usually a very stable situation.
- Decide what is most important to you for the game. Is it frames-per-second or is it really smooth graphics with deep detailed views. You may have to compromise by reducing one to enhance the other in the game settings.
- Consider a lower resolution or running in a windowed mode. The fewer pixels to process, the less work and consequently the cooler the GPU can run.
- Go Low Tech: For many people, simply removing the side of the case and pointing a desktop fan at the internals will provide more than enough cooling. If the noise from the fan is problematic, turn the sound up or wear headphones; it's better than melting your graphics card.
 Out of Date Software
It is rare that any piece of software is absolutely perfect. Publishers continually seem to find things that need improvement. Consequently you need to make certain you are still up to date.
- While Steam should regularly provide an updated game patch, and the installation included an up to date version of Microsoft Direct X, check to make sure both are in fact the latest. You never can tell, they may have corrected something that will help.
- Consider updating your graphic card drivers. Usually the manufacturer's site will have an option to download and install the latest drivers and it is usually free from them.
- On a deeper level make sure your operating system is up to date by running the appropriate update software.
- Finally, make sure that your BIOS and motherboard chipset drivers are up to date by visiting their manufacturer sites as well.
 Changes, Complexity, Interference and Dying Hardware
These require you to play detective by trial and error.
- If you have recently updated or changed some settings prior to the start of bad behavior, trace back to when the change was made and roll back drivers and settings to how the system was configured then.
- Consider running the game in compatibility mode. It sounds strange, but sometimes moving the software environment back to a simpler time can work. If it doesn't help there is nothing lost, you can always turn it off.
- Consider the possibility of interference from other applications running in the background. You can use programs like Task Manager to temporarily disable non-essential tasks. If it doesn't help, again nothing is lost.
- Finally, consider that some piece of hardware may be wearing out. It can be anything: sound card, network adapter card, graphics card, etc. One big clue that hardware may be dying is that you get similar crashes running less demanding different applications. It is tough to track this down since it usually requires swapping out the possible offenders on another similar rig, where you look to see if you get similar crashes.
Given all of the possible motherboards, BIOS's, graphics cards, memory configurations and software on any single computer there are literally billions of possible combinations. So the advice or solutions offered here are in general terms. You apply them at your own risk. One way to reduce that risk is to make back up copies of things like the registry, and to make restore points before undertaking any change.
If you are uncomfortable with working on the interior of a computer do not do so until you have had some instruction. It is very easy and expensive to short out CMOS devices with static charges.
Tweaks are changes to software settings to address problems.
After every patch release, all of the tweaked settings should be returned to a vanilla default status. This is because a new patch can sometimes correct the problem that motivated one tweak, but cause new problems with other tweaks. For example, running on a Vista system in compatibility mode for Windows XP might have reduced crashes for patch 1.4, but turning off that compatibility mode for patch 1.5 could reduce crashes even further.
 Increasing Frame Rates
 V-Sync tweak
One frequently encountered piece of advice to increase the frame rate is to disable the V-Sync within Skyrim. V-Sync (vertical synchronization) is designed to allow each frame to start at a consistent position so that each is presented completely and cleanly. Turning it off may result in an increase in the frame rate but there may be a cost in that frames will tear with sudden movements or there may be an odd horizontal ripple on the screen. If you chose to try turning it off here is an example of the steps under Vista.
- Open C:\Users\<user name>\Documents\My Games\Skyrim\SkyrimPerfs.ini
- In case there is a need to revert, save as: SkyrimPerfs.ini.old
- Re-open it to work on the active .ini file (in Notepad).
- Under Edit, select Find and enter: iPresentInterval
- Change the value to zero (iPresentValue=0) or add this if it was not there.
If it is not the case that the frame presentation is adequate and the frame rate has increased, then it is easy to revert either by erasing the .ini file and renaming the .old version or by making iPresentValue=1 and saving it.
 Priority setting tweak
Using Task Manager it is possible to set Skyrim to a higher priority. Each time you start the game do the following.
- Simultaneous press Ctrl-Shift-Escape to run Task Manager.
- Start Skyrim.
- Alt-Tab out of Skyrim to the Task Manager.
- Select the Processes tab in Task Manager.
- Right click: TESV.exe
- Choose: Set Priority
- Select: Above Normal
- Alt-Tab (or mouse click) back to Skyrim.
Unfortunately this tweak reverts naturally and must be done every time you run Skyrim.
If you have a crash that occurs every time a given event occurs please note the game version, operating environment, circumstances, nature of the crash and any attempted corrections in the talk section. We cannot promise a solution but will attempt to duplicate the crash and contact Bethesda or Steam as seems warranted.
