We have some company laptops at our office which are experiencing some problems.
The laptops will stop responding, seemingly randomly, for periods of about 10-20 seconds.
This is getting increasing frequent. Right now it happening about once every 5-10 minutes.
When this happens the hard drive light is solidly on, but they do not make that normal ticking noise that hard drive make.
You can actually still use the laptop, but it seems to only let you do things that are cached in RAM. Like when it happens, I can still switch between open tabs in FF and other applications. But if I try to access anything from the hard drive, the application locks up (greys out, and shows at "Not Responding") until it stops stalling.
I see nothing in the Windows event viewer (in both administrative events, and hardware events) at the time this occurs.
I have run
chkdsk during boot, with no reported errors.
The laptop specs are:
- Core 2 Duo T7500, 2.2 GHz
- 2 GB RAM
- 150GB HDD, 10GB free (Hitachi HTS541616J9SA00 ATA)
- GeForce 9500M GS gfx card
- Windows 7 Professional
I have already tried the following:
- Registry cleaning
- Hard defragging
- Virus/Malware/Spyware scanning
- Uninstalling unused programs
Can anyone shed some light on what is causing this, and/or what step to take in order to debug and solve this problem?
