Can hardware get damaged from restarting a computer too often?

Will restarting the computer a lot (about 10 times in 2 minutes) damage the motherboard?

I'm always installing new programs and testing new operating systems on my computer. (I know you can do the same in virtual machines, but they do not have the same hardware as the host.)

For this reason I need to restart my computer all the time (pressing the reset button), either because of a virus or crash.

I heard that the hard disk may become damaged and I could lose important information, but I'm worried about the other components, like the processor, RAM or motherboard.

Can these components also be damaged if continuously restart my computer?

Solution

It probably won't damage any of the hardware. Technically restarting shouldn't damage the hard disk either, but it may damage the filesystem (software on the hard disk). However if you have to reboot constantly due to viruses and crashes, you should probably change your online passwords immediately (especially banking) and enlist someone to clean up/zero the drive/ reinstall system ASAP. See some of these pages for info on secure banking with a live cd:

It may eventually damage the hardware doing so many reboots, but it probably not for a long time (years).

> I heard that the hard disk may become damaged Correct, but that means actually turning the system on and off, not simply rebooting.

Hard disks go out most frequently due to having moving parts. Fans come in 2nd (moving parts), and PSUs are 3rd (lots of electricity and whatnot).

The initial spin up of hard drives stresses them a lot.

Still superstitious about it.
