SOLVED: (adding the solution to help others.) Problem was in the mouse. Brought new mice and the problem disappeared.
----
using w8 for last 3 years. PS/2 3D Optical Mouse was previously working well ever since.

recently I bought a new mouse exactly of the same kind, just from a different vendor (QHMPL - QMP-220)

Ever since, the mouse stops responding at all at random intervals.
I wasted hours figuring it out and found that I don't need to sign out or reboot or whatever,
I just need to unplug and replug the mouse in the PS/2 socket,
and then it starts working.

I have not installed any driver for it, nor did the vendor provided any. It just uses whatever MS has provided as default.

Several sites are mentioning several people facing similar problem, but none that I visited could provide a solution.

My Keyboard is also PS/2, and is working well ever since, though people have reported same problem with their kbd also.

What could be the mouse problem and please suggest solution for it.

Thanks.

You might have to return that mouse and get the exact make and model of the original working mouse, or, get one from Staples/Office-Max/Depot or Fry's Electronics.

Why? And have you tried putting the old mouse back in to see what happens? If it now stops responding, it is your computer. If it works, it is the new mouse.

Note that PS/2 is ancient technology. You may have to go with USB.

This problem doesn't have a pattern. Some times it occurs 3-4 time a day, Sometimes it doesn't occur for 3-4 days.

I bought new mouse because previous mouse was not working properly, so putting that mouse back and waiting for 3-4 days for the problem to occur will mess up with my work.

pc has fixed no. of usb ports - 2 at front, 2 at rare, Now, my net dongle, tv tuner are already connected to usb sockets, only 2 will be left and if I put mouse, keyboard there, I will be damned if I need to put any pen drive or anything.

of course, I can bring additional multiusb card, but that would be - first creating need which was not there, and then spending money to fulfill the need.

Also, I have found that usb sockets needs regular use. otherwise they can jammed, or they even corrode, when I put my tv tuner in usb socket, every some 4-5 months, it stops working and I have just to unplug replug it and it starts working.

2 ps/2 sockets are there which are lying unused and can't be used for anything other than keyboard and mouse, so I prefer to use ps/2 ports.

And it seems to me that there is no benefit of using usb ports over ps/2 ports. If putting keyboard and mouse in usb ports will reduce power consumption, or will improve the accuracy of the devices, or will increase their lives, I am all game to usb port.

In general, ancient technologies are more rugged and durable as compared with latest technologies which are fragile.

Thanks for suggestion.

Actually, I searched on net and found that ever since arrival of w8, several people are facing and reporting the same problem.

That is why I reported hoping for a tried out solution.

or they even corrode
Nah! Not likely unless left exposed (nothing connected to them) to an excessively humid environment for a very long time. Dust, however, can collect in them as case fans can draw air (and dust into them). But again, not if something is connected.

Of course, if something corrosive was spilled on them (cola, coffee, etc.) that could cause corrosion.

More likely is just the (sadly) inherent problems USB interfaces often have. :( They just have not proven to be as reliable or "universal" as their designers planned. And this is not isolated to, or predominately with Windows 8. What happens when you unplug and re-insert is the system rediscovers new hardware and reconfigures the port and communications. Again - nothing to do with the physical properties of the connection.

2 ps/2 sockets are there which are lying unused and can't be used for anything other than keyboard and mouse, so I prefer to use ps/2 ports.
Well, nothing wrong with that.

of course, I can bring additional multiusb card, but that would be - first creating need which was not there, and then spending money to fulfill the need.
Well, they are not that expensive and external hubs do have their distinct advantages. For one, you can bring rear ports out front to a convenient location, like under your monitor. Also, if you get a self-powered hub (which you should), you don't overload the motherboard's controller by attempting to draw too much power through the motherboard's USB port. Note this is a common problem.

In general, ancient technologies are more rugged and durable as compared with latest technologies which are fragile.
No. Even as a general statement, that is just not true. What is true is PS/2 is not a "universal" I/O connection. PS/2 was designed specifically for keyboard and mice HIDs (human interface devices). So when a computer senses something connected to a PS/2 port, it knows it can only be a keyboard or mouse. Even the BIOS automatically knows how to interface with it. With USB, it could be any of 1000s of different things. And besides, USB is pretty ancient too.

Anyway, it sounds like your new mouse may be faulty. So until you try another, it is "hurry up and wait".

Thanks for useful info provided in detail. I will sure buy a new mouse and put it.

Though it will be ps/2 again. :) Actually your's and other above replied convinced me further that using ps/2 is better.
Thanks.

Well, I did not intend to convince you PS/2 is "better". Frankly, I do believe USB is "better" - when it works properly. And most of the time, it does. And for sure, there are many more USB mice to choose from.

PS/2? I don't have any of those ports in my box. I would suggest (as above) getting a powered USB hub.

Really? I just bought a brand new Gigabyte Z170 motherboard and even it has a combo (purple and green) PS/2 port to connect either a PS/2 keyboard or a PS/2 mouse as seen in this image.

I was also wondering how could it be, because I have never seen any lappy or pc without two ps/2 ports so far.

I thought maybe some new model has come which has discarded ps/2 ports.

or, could be that Odos270 could not recognize ps/2 ports. :) just kidding.

which model it is. could you please post a pic?

Well, now sorry but I might have misspoke because I was talking only about PC motherboards. Notebooks are different.

But to your comment about there being two PS/2 ports on PCs, having only one (purple/green) has been pretty common for many years. Just looking at the 6 PCs here, only the oldest using an ASUS ITX board from 2008 has two (a green and a purple) PS/2 ports. All the others have just the one port. And the two notebooks (Dell and Toshiba) have none.

You can look at my system specs. HP H8-1534 ENVY. No PS/2. 4 USB2 in the back. 2 USB2 in the front. 2 USB3 on top.

I don't disbelieve you. And I didn't say all motherboards have them. I just said having one is "pretty common".

Now for sure, your computer is a factory built computer. No surprise HP would cut that support out to save a few pennies - especially when they provide a USB keyboard with their computers.

But if you were to research motherboards on Newegg for example, you will find many, if not most, still have at least one PS/2 port.

providing none ps/2 could be ok, as the manufacturer might be thinking of users using everything usb only.
but giving just one ps/2 seems more odd, because then the user can put either mouse or keyboard but not both, but as a habit, any user willing to use ps/2 would get both mouse as well as kbd as ps/2.

could be that one ps/2 is giving not for mouse/keyboard, but just to give a ps/2 connectivity port for the box, for any use, and the manufacturer still thinks users would be using usb mouse/ keyboard.

it is like several newer boxes having one mini-usb (fire) port also, which is usable, I guess, only for handset charging or directly accessing mobile's inner memory from pc.

for that matter, a usb to ps/2 convertor would enable a usb mouse/ keyboard to be put in ps/2 port
whereas, a ps/2 to usb convertor would enable a ps/2 mouse/ keyboard to be put in usb port.

I wonder why manufacturers are not giving BOTH ps/2 as well as usb ports in mouse/ keyboard. It wouldn't raise price so much, but will give absolute freedom to users.

And that is the industry trend. PS/2 support is legacy support. And there are many USB keyboards and mice to choose from, but few PS/2. Just doing a quick search on Newegg showed nearly 800 keyboards with only 69 having PS/2 support and some of those were only with adapters.

As for only one PS/2 port, that actually makes sense. Again, USB is the industry standard and about the only time you might need PS/2 support with modern systems is when troubleshooting in the BIOS - and you only need a keyboard for that.

True, it would not raise the cost very much but many buyers will buy this board because it cost $1 less than that board. Plus, more and more boards are getting smaller and smaller and PS/2 ports and circuitry to support it takes up valuable real estate. And frankly, I don't like paying for something I will never use.

This is just life. Motherboards no longer support centronics or AGP interfaces either. Same with floppy disk controllers and even EIDE disks.

Going by all your suggestions, I bought one ps/2 mouse and one ps/2 keyboard, and also one usb mouse and one usb keyboard,

first I put new ps/2 mouse. And it worked perfectly well for some 24 hours without that "not responding" problem occurring even once.

then I put new usb mouse. And it worked perfectly well for some 24 hours without that "not responding" problem occurring even once.

So the issue is solved.

The problem was indeed in the mouse.

I have also bought ps/2 to usb connector, and I will now check the old problematic mouse
1. by changing its port to other ps/2 port.
2. by connecting it to usb port through ps/2 to usb connector.

let's see what it comes out.

Thanks for solving my problem. Another gig of thanks for a lovely insight about ps/2 vs usb.

marking this thread as closed. Hope that is ok with you all.

Thanks.
