Virtualbox causes Windows 7 restart

Virtualbox causes Windows 7 restart. Recently, we want to increase the T410 memory from 2 GB to 4 GB. However, we find that the system restarts occasionally regardless of the brand of memory used. At first, I thought it was a hardware problem with T410. www.2cto.com later used a Samsung memory identical to the original memory and found that it was still restarted, so I began to suspect that it was a software problem. After several days of observation, we finally found that it was a ghost of virtualbox. As long as virtualbox is not run, the system will not restart. As a last resort, replace the Virtual Machine with vmware. My Windows OS is 32-bit, and virtualbox is installed with 64-bit CentOS. Author LiveDead
