DayZ BIOS Error: How to Fix Startup Crashes on PC, Xbox, and PS5

DayZ has earned its cult status in the survival genre but what happens when you’re stuck at launch with a BIOS error? Players across PC, Xbox, and PlayStation are reporting cryptic messages like 0x0005000F or STATUS_ACCESS_VIOLATION that block the game entirely.

This guide unpacks what these BIOS errors really mean and how to fix them for good.

Common BIOS Error Codes and What They Mean

DayZ BIOS-related errors may sound technical, but they’re often indicators of network failures, authentication issues, or file-level conflicts—not your actual BIOS chip malfunctioning. Here’s a breakdown of the most common error codes and what each one signifies.

PC Fixes for DayZ Startup Crashes

DayZ players on PC often encounter crashes tied to memory exhaustion or conflicting background services. These issues can usually be fixed through system tweaks or by resetting local game configurations.

Out of Memory Errors

This error usually appears after a large update or mod install and is linked to an overwhelmed page file or cache. To fix it:

Disable Steam Cloud Sync

• Go to Steam > DayZ > Properties > General, and turn off Cloud Sync to prevent corrupted settings from syncing.

Delete DayZ Configuration Folder

• Navigate to Documents\DayZ and remove the folder. Backup character profiles if needed.

Increase Virtual Memory (Page File)

• Open Control Panel > System > Advanced > Performance > Virtual Memory.

Choose “System managed size” or set at least 2000MB if using an SSD.

STATUS_ACCESS_VIOLATION Crashes

This crash stems from file conflicts or improper memory access, often caused by outdated drivers or overlays.

To resolve:

• Add the launch parameter -nocharmenu in Steam Launch Options
• Update GPU and motherboard chipset drivers to the latest versions
• Disable all overlays, including Discord, Steam Overlay, and GeForce Experience
• Run System File Checker using sfc /scannow in an elevated command prompt

Bad_Module_Info Crashes

When DayZ fails to launch or crashes immediately, it may throw a Bad_Module_Info error, typically due to system instability or incompatible files.

To fix:

• Switch to DayZ Experimental Version via Steam
• Copy chars.DayZProfile from the Experimental config folder into the main DayZ config folder under Documents

Console Fixes for Xbox and PlayStation Players

Console users often see BIOS-related startup errors, but most are tied to server-side issues or network problems, not hardware faults.

Xbox and PS5 Startup Fixes

These steps have been effective for resolving common console crashes:

Check Server Status

• Visit status.dayz.com to confirm if the issue is on Bohemia’s side.

Restart Console and Router

• A full network reset can clear temporary authentication problems.

Clear Cache

• Xbox: Hold the power button for 10 seconds, unplug for 30 seconds, then reboot
• PS5: Boot into Safe Mode and choose “Rebuild Database”

Reinstall DayZ

• If all else fails, uninstall and reinstall the game to ensure a clean install without corrupted files.

Advanced Troubleshooting

If crashes continue despite the above solutions, deeper system-level adjustments might help.

Update BIOS and Chipset Drivers

Some memory-access issues stem from outdated firmware:

• Find your motherboard model using msinfo32
• Download the latest BIOS and drivers from the manufacturer’s site (e.g., ASUS, MSI, Gigabyte)
• Carefully follow instructions when updating BIOS to avoid system failure

Run Memory Diagnostic Tools

To check if your RAM is faulty:

• Search Windows Memory Diagnostic from the Start Menu
• Restart and run the scan—it will report any errors automatically

Perform a Clean Boot

To identify background service conflicts:

1. Press Win + R, type msconfig, and press Enter
2. Go to the Services tab, check “Hide Microsoft Services,” then disable the rest
3. Restart the PC and try launching DayZ again

Final Thoughts

Before reaching out to support, ensure you’ve done the following:

• Verified game files via Steam or console
• Updated graphics drivers, BIOS, and chipset software
• Increased virtual memory and cleared cache folders
• Disabled overlays and non-essential background services
• Rebuilt your console’s database or cleared MAC cache

BIOS errors in DayZ are more about networking and memory management than your actual BIOS. With the right tools—from verifying files to tweaking virtual memory—you can get back to surviving zombies in no time.
