I am having a serious problem. my ups is constantly fluctuating and making my computer power up-down. Resulting into my keyboard constantly blinking and also my mouse . My keyboard got malfunctioning two times. bought two new keyboard.this the third and i think it will also end up like that. Please help before it gets all worse. Luckily my mouse is still functioning.
this is what happens. I use my keyboard and after sometime my ups starts making nose . after nearly 20-30 times happening it gets malfunction. some of my keys gets replaced with multiple keys and sometimes it returns back to normal.
tried re installing driver, re installing windows nothing happened

Sounds like the battery in your UPS is not holding a charge. Remove UPS since it sounds more unreliable than conventional wall plug power. You should be able to replace the battery. If the UPS is more than 3 years old, it is due for a replacement battery (your mileage may vary, check the documentation from your UPS for recommended replacement interval).

If the UPS is causing that (if the symptoms go away when the PC is plugged into the wall directly) then replace the UPS.

No UPS should cause problems just because the batteries are bad. It should flash a "Replace Battery" light and keep on running.

@Recycled -- I agree that a properly functioning UPS shouldn't cause problems because the battery won't charge. And I agree that it should be removed from use. A cheap UPS is creates a false sense of security. A quality UPS with appropriate automatic shutdown software is what is required for true security

The easiest way to find out if the UPS it really the problem would be to remove it from the power string and replace with a simple surge suppressor. If that eliminates the problem then you can definitely say it is the UPS.

should i connect surge suppressor to ups plug ports then from there to cpu?

Unplug the PC and monitor from the UPS and the UPS from the wall. Plug a simple surge protector power strip into the wall and all the components into the strip....
