Out of curiosity, or because someone told you to, you open Event Viewer and find hundreds of red errors and yellow warnings. When Windows 10 Event Viewer full of errors appears on a PC YYPAUS Login that seems to work fine, it is easy to assume something is seriously wrong.
In reality, almost every Windows PC records many errors. Event Viewer logs everything, including harmless timeouts, services that start a little late, and apps that retry a connection successfully.
Scammers sometimes exploit this. A caller claiming to be from “Microsoft” may ask you to open Event Viewer and point to the errors as proof of infection.
The skill is knowing which entries deserve attention and which can be safely ignored.
What Might Be Causing It
Errors pile up for these reasons:
- Services and apps log routine failures that resolve themselves.
- Drivers report minor issues during startup or sleep.
- Updates and installers record temporary problems.
- Genuine hardware or software faults, which are far fewer.
A PC running smoothly with many errors in Event Viewer is completely normal.
First Steps to Try
Focus on what matters.
- Ask yourself whether the PC has a real symptom, such as crashes, freezes, or restarts.
- If not, close Event Viewer. The errors do not need fixing.
- If you do have symptoms, type “reliability” in the search box and open “View reliability history.” It shows a simpler timeline of crashes and failures.
- Click a day with a red cross to read which program or Windows component failed.
- Note the error source and event ID for anything that repeats around the time of your symptoms.
Reliability Monitor is far easier to interpret than Event Viewer for most people.
If the Problem Continues
Investigate the entries that matter.
- In Event Viewer, open Windows Logs > System and filter by Critical and Error.
- Look for repeated entries from sources such as Disk, Ntfs, WHEA-Logger, or Kernel-Power, which point to drive, hardware, or power problems.
- Search the source name and event ID online for explanations.
- Run chkdsk, Windows Memory Diagnostic, or driver updates depending on what the entries suggest.
- Ignore one-off entries that do not match any symptom.
If several disk errors appear, back up your files immediately.
Protect Your Data First
Never call phone numbers from pop-ups or allow remote access to people who claim Event Viewer shows infection. Microsoft does not make unsolicited support calls. Do not delete logs or change settings based on random errors.
The Bottom Line
Event Viewer is full of errors on almost every PC. Investigate only when you have real symptoms, use Reliability Monitor for a clearer picture, and pay attention to disk, hardware, and power entries.
