My keyboard keeps disconnecting at random times,when there is a clicking noise from my ups..It does'nt happen everytime when the power swithces to the ups but mostly when the power switches from main to ups it disconnectes my keyboard for 2-3 seconds and connects it back(some times it plays the usb sound in the background)(sometims it would just freeze and get back in 2-3 seconds
)..If i would be gaming at that time it becomes really annoying because the game takes my last input before the keyboard disconnected(keeps taking that input until i escape and get back into the game..doesn't get back to normal until i go to the game's menu and come back...Is there a way to solve this??It is a usb keyboard...Really don't understand why the keyboard would disconnect when the more swicthes to the ups....Iam worried about this because i have trrible voltage flutuations here because of which the ups would continuously be switching...

The clicking sound is your UPS' batteries being used.

It is perfectly normal for the system to 'freeze' when the UPS' battery is being used to provide electricity since there is inadequate electricity for the computer to run at its normal speed.

A new power supply may help however the main issue is the instability of the powerlines/outlet.

I assumed that your were looking for a solution however a new power supply probably won't stop the freezing either.

Just happened again with nfs rivals...And now there was a click noise fromthe ups and the key got stuck and then two more clicking noises,screen froze with the second and third clicking noises..came back to normal again,but only after i alt tabbed out of the game and came back...escape button did not work this time..even in the escape men,the game took the same previous input the upper arrow and the map pointer kept moving upwards until i alt tabbed...the same thing was happening before but ith assassin's creed 4..even there the same keyboard issue and the screen would freeze for 1 or 2 seconds and come back,but then i thouhgt the freezng issue ws because of the game itself rather than being related tih the keyboard issue..But now confirmed both are related..happened in two games...And my operating system is windos 7 64 bit9ultimate edition)..just froze twice when typing this thing...Would it be a problem with the ups..will changint the ups fix the issues...

Why do you suspect the power supply as i have clearly mentioned the problem occurs only when there is a clicking noise fromt he ups...And i know the psu is not of good quality..but this is what was available at my time of purchase...No antecs or seosonic s were available at my time of purchase and other models were too overpriced which i could not afford...I live in india and the options at modest price ragne are very few here...This has started to happen very recently..

While a clicking noise is common from UPS's when switching from grid power to battery, this statement



has me very confused - I've never experienced a performance drop while on UPS power - if you try to draw more wattage from the UPS than it can handle, the UPS shuts off or an alarm starts wailing (even with power from the grid) - I know of no desktop PC that'll drop it's performance because it isn't getting enough power (a feature found on laptops which are designed to run on battery) - a desktop simply shuts down or BSOD's. I think I'd be more inclined to believe a faulty USB controller, bad capacitor or weak poly-fuse.

I think I would be inclined to try a different USB port a bit away from the one the keyboard is currently in - it could even be an issue with the keyboard or it's drivers but I would start by changing the USB port for the keyboard

I will try a different port..But today when i was surfing the internet,suddenly there was a power surge here.So the power switched to ups and the computer restarted immediately after the power switched to ups...Don't think its a problem with the usb port adn i also doubt there would be any bad capacitors as the whole system is just a month old...

Okay, there is an issue which may be presenting itself (in a way I haven't seen before) - if the UPS is not "sine-wave" compatible and your new PC features an Active PFC (power factor correction), there is an issue when switching from the grid to UPS, the solution here may be to get a "pure sine-wave" or "sine-wave compatible" UPS. Could simply be a "compatibility" thing going on here.

I would tell you to switch out the PSU for one that is not Active PFC as a less expensive option but virtually all newer, quality PSU's have Active PFC (I'll see if there aren't some I can find that'll work here, it'll take a little research)

Alright then...it doesn't seem to be an usb port issue now..In day time when i use the pc i don't see the issue...That's because there is no voltage fluctuation in day time here..So it is a problem with the ups right...

I'm thinking there is a less expensive way to ensure that is the problem... perhaps this Gigabyte Superb 550P for ₹2800 (I'm actually cringing while suggesting this - it's a 450W PSU, not 550 as it's model number would have you believe) which does not feature Active PFC. It's not a highly rated PSU although HardwareSecrets did find it was okay in some conditions. For the price for troubleshooting purposes, I would think it would be okay.
On the flip side of that is the time and effort of replacing a PSU in the machine, it may be worth it to you to simply get an Active PFC compatible UPS (which is a whole lot easier to set up than installing a PSU)
