Windows 7 My new notebook keeps on shutting down when I am browsing the internet

[aoreta]

Has anyone encountered your PCs shutting down all of a sudden while browsing the internet? I have observed that this mostly happens on Firefox (am using ver4) while on IE8 it only happens quite seldom. If I am using other applications, I won't encounter this issue even when playing any games. My OS is Win7 SP1 on a 64bit machine.

I am not encountering ang BSOD, the muchine just dies (does not restart itself). I've already checked the system event logs and there are no malicious errors that could be seen. BugCheck in event ID 41 is 0. I've also tried running the default Windows Memory Diagnostic tool and even downloaded MemTest to futher check but no error reports are being thrown, so I am no longer looking at a possible memory issue.

Do you guys have any idea on what else to check in this scenario? This notebook was just recently bought and all MS updates have been installed including latest SP. I have already looked at the Device Driver and there seems to be no issue with any driver. Is there any other log that I need to look at?

Cheers,
Adrian

Adrian, Experiencing sudden shutdowns without a Blue Screen of Death (BSOD) can be frustrating. Since you've already taken some steps to investigate the issue, let's explore a few more troubleshooting steps to help identify the root cause of this behavior on your Windows 7 SP1 machine. Here are some additional suggestions to further diagnose the sudden shutdown issue:

1. Check for Overheating:​

• Software Monitoring: Use monitoring tools like HWMonitor to check the temperatures of your CPU and GPU during normal use and especially while browsing the Internet. Overheating components can cause sudden shutdowns to prevent damage.

  2. Power Supply and Connections:​

• Check the power supply connections to ensure they are secure. A faulty power supply or loose connection can cause sudden shutdowns.

  3. Event Viewer:​

• Look for any critical or error events in the Windows Event Viewer that correspond to the time of the shutdowns. Pay attention to any patterns related to specific services or components.

  4. Check Power Settings:​

• Make sure that your power settings are configured correctly, especially the settings related to automatic shutdown on critical battery levels.

  5. Driver Updates:​

• Even if Device Manager doesn't show any issues, consider checking for driver updates from the manufacturers' websites. Outdated or corrupt drivers can cause unexpected issues.

  6. Malware Check:​

• Run a full system scan with a reliable antivirus program to ensure that there are no malware or virus infections causing the shutdowns.

  7. Hardware Diagnostics:​

• Perform a more comprehensive hardware diagnostic using tools like Prime95 for CPU stress testing and FurMark for GPU stress testing.

  8. System File Checker (SFC):​

• Run an SFC scan to check for and repair any corrupted system files that might be causing the shutdowns.

  9. Check for Windows Updates:​

• Make sure you have all the latest Windows updates installed to address any known issues. By going through these steps, you can further narrow down the possible causes of the sudden shutdowns on your Windows 7 system. If the issue persists, feel free to provide more details for further assistance. Good luck in resolving this issue, and I hope this information helps you find a solution to your problem!
