Something strange happened while I was using my PC. All of a sudden, the mouse and keyboard stopped working. The laser on the mouse was still glowing, but there was no cursor. The num lock, caps lock and scroll lock lights on the keyboard kept blinking every few seconds, and they keyboard was unresponsive as well. I had to shut down the computer a remote app on my android tablet. I had something similar happen last night. The mouse suddenly died, but the laser wasn't glowing. I unplugged and plugged the mouse back in and it was fine. The keyboard was still responsive. The keyboard is an IBM Model M connected to the computer via a PS/2 to USB adaptor. The mouse is a Microsoft Wheel Mouse Optical connected to the computer via USB. This has happened twice today and it just started today. This is somewhat of an urgent issue, as I need to get my final program for my programming class done by tomorrow. What could be causing this? The computer is a Lenovo H430-2558-1ZU. 

 

The specs are as follows:

3.3GHz Intel Core i3 2120

4GB DDR3 RAM

EVGA GTX 750

SeaSonic S12II 520 power supply (upgraded from stock)
1TB Seagate ST31000524AS

{guessing]

If you are using your computer a bit more and at a higher level of activity I'd be looking at the possibility of a heat problem. Computers protect themselves by shutting down operations to prevent overheating from reaching a destructive level.

...and if you're in a programming class are you sure you haven't been hacked/somebody loaded malware or some sort of virus to mess with you?.....you might include a good malware scan in the to do list....

It has started doing something else now. If I leave the computer alone for awhile and come back to it later, I find that it is completely powered off, like it was shut down. No one in the house claims to have shut it down. This has happened four times for the past 2 or 3 days. Also, the keyboard and mouse stopping working thing has happened several more times, and keeps happening. I did do a full scan with Malwarebytes but it didn't find anything. I will be doing a clean install of the OS tomorrow. I hope it will solve these problems.

the system shutdown is concerning.  can you monitor temps with something like GPU-Z or HW Monitor?  Heat makes sense for the shutdown, or a video driver conflict.  Have you loaded new graphics drivers lately?  I've had issues recently with older peripherals acting up with weird errors after loading the new combo win 7/win 10 compatible drivers that a lot of companies are rushing out the door (plus with microsoft downloading getting ready for 10).  loading older drivers fixed that for me (specifically, a logitech G15 keyboard which I still dig, died after the new combo logitech update-and possibly a win 7 to 10 driver update, I may never know.-- loading the old setpoint driver in combo with the new driver software fixed it completely.) if your peripherals are USB you might also check your USb drivers and even take a look at device manager to see if there's an error showing there.  but the system shutdown speaks to heat or video or some other major conflict.

Well, it turns out the problem with the keyboard and mouse disconnecting was caused by the Microsoft mouse I was using. With the Microsoft mouse, the cursor would sometimes lag and stop dead in it's tracks for a second or more. I went back to using the Lenovo mouse the computer came with, and the problem is gone. It's been four days and the problem with the keyboard and mouse disconnecting has not happened again. As for the shutting down when left alone, that seems to have been resolved by the clean install of the OS.
