Netbeans 8.0.2 `scan for external changes` suspended, and no auto popup

Question

I am using NetBeans as my IDE. After working a few hours, I got the following problems

1. It got stuck with scan for external changes suspended

2. and after this came, the auto-load also got fails. It shows please wait... only.

Due to this I am planning to change my IDE. Is there any way to overcome this? I thought it was due to the issue with my slow computer. I just formatted and upgraded it. Then also it shows the same issue.

My NetNeans is the small package with PHP and HTML only.

3. It also cause high CPU usage sometimes

My operating system is Windows 8.1 with 4 GB memory and i3 processor
