Event ID 6013 — System Uptime

What is this error?

Windows logged the system uptime. While not an error itself, checking uptime after a crash helps determine if the system restarted unexpectedly.

Common causes

  • not an error event
  • used for diagnosing unexpected restarts
  • paired with Event 41 and 6008 for crash investigation

How to fix it

  1. Compare uptime with crash timestamps to verify unexpected restarts
  2. Not a fixable error itself

Too many steps? Crashless can diagnose this automatically — checks your drivers, temps, VRAM, and 400+ known error patterns.

Detailed analysis

Event ID 6013 (Source: EventLog) logs your system's uptime in seconds. While it's not an error, it's a useful diagnostic tool when investigating crashes.

How to use Event 6013 for crash diagnosis:

  1. Open Event Viewer > Windows Logs > System, find Event 6013 entries
  2. Convert the uptime seconds to hours/days
  3. If uptime resets to a low number between entries, the system restarted unexpectedly
  4. Cross-reference with Event 41 (Kernel-Power) and Event 6008 (Unexpected Shutdown) at the same timestamp
  5. A pattern of short uptimes during gaming sessions confirms repeated crash-restart cycles

This event is purely informational — the fixes depend on what caused the restart. Check for:
- Event 41 with BugcheckCode for BSODs
- Event 4101 for GPU TDR
- Event 18 (WHEA) for CPU hardware errors
- Temperature monitoring data around the crash time

When to seek help

If this error keeps happening after trying the fixes above, it may point to a deeper hardware or system issue. Consider professional help if:

  • The crash occurs across multiple games or applications
  • You see the same error after a clean Windows install
  • Your PC is less than a year old (could be a warranty issue)
  • You smell burning or hear unusual sounds from your PC
