PC hardware--CPU & Motherboard & RAM/hdd led


I just got a used Asus computer with P5Q motherboard with Intel i7 CPU and 2gb Nvidia card..  Everything works well including dual boot windows7/Linux Mint.  There is 1 sata drive and 1 pata drive.

My question:  the HDD activity led flickers constantly with either OS, about 1 small flicker per second.  No data is being transferred to the net.  Virus and malware scans show that all is OK.

Do you think there is a problem or could this be considered normal??

Thanks in advance for your reply.

This can be considered normal activity. A lot of activity that would still cause the hard drive to read/write data would be small system background processes that log certain things, anti-virus programs scanning while the computer appears inactive, page file swapping, and small changes to the regular running registry at any given time. You don't have anything to worry just based on the hard drive indicator.

Have a great day!

I can answer most No POST problems, compatibility between parts, upgrade options, troubleshooting, etc. Before you ask me a question, please do some research. I do not give PC speed reviews for video games.


Many, many years of experience working with the hardware components of many types of computers including desktops, laptops, kiosk computers, and even running Windows 3.1, 95, and 98 on the PSP (Sony PlayStation Portable). I've replaced capacitors on desktop motherboards making them working like new again with a high success rate. This is my hobby/job every day.
