Yesterday, I was playing fifa 17 and system restarted twice and third time I finally shut it down. But when I tried turning ON my PC it doesn't turns on. I have removed battery, RAM, graphic card, and put them on motherboard back but still it doesn't turns ON. All the fans and CPU fans and motherboard lights turns on for 2-3 seconds and then it goes off. After 3-4 seconds it again tries to ON by self but still it doesn't turns ON.
 
 
Kindly assist.

That's a typical power supply failure.

The PS circuits have protection circuits to prevent it from damaging anything should voltages or current exceed their specs.  This looks like wht the PS is doing, powering on, sensing eother an over voltage or a short and shutting down and restarting.  Removing all but essential memory and cards, see it it still fails.

Hello friends,

 

Actually I have checked with local technician. When he tested at his shop my pc got ON. Fans of graphic card did run at the time of boot and later on it stopped. 

So now I tried running the game (Fifa 2017 & WWE 2K18) it got restarted. So I tried the same thing for 2-3 times. 

 

The strange thing I noticed was that fans of graphic card was not running at all which was causing my PC to restart. So, the technician used another graphic card but this time fans were running continuously from boot to idle desktop. So now when I runned the game it got restarted again.

 

So now it was the PSU to be tested. He changed the PSU and now restarted the PC. My PC did boot up and now when I executed the game the thinghs were PERFECT!!!!

 

The fans of graphic card was also running along with the game and PC worked fine.

So it was the PSU that was causing the issue and i has to be changed.

 

So please let me know do you all think it was PSU's issue or may be any voltage up-down has caused the issue. I also have UPS where the plugs of my monitor, CPU and 2.1 speakers are connected. Is this may be the issue that UPS might have failed or UPS could not take the load??

 

Because from last 2 days I have been testing my UPS by turning OFF the plug of wall mount the light goes red and my CPU also gets restarted which means the battery of UPS is not taking the load of my PC.

 

Kindly suggest !!!!!!!

Well, spikes on the line from a UPS not taking up the load quick enough, as when the batteries are weak, causing a gap in the voltage, enough to restart the power supply.  Repeated interuptions can cause power supply failures.  The faulty UPS could have also failed to provide a clean sine wave, usually degrades to a square wave and that's not good.

Yes, thanks for your assistance.

 

Yesterday I did check only my monitor through UPS and UPS couldn't take the load so in that case the battery is gone. So changing the battery will do for me, right?

 

Secondly, I had Masterwatt lite series 500 on replacement they gave me Masterwatt 500, so is it the same thing? They told that lite series has been obsolete is it true?

 

Can somebody please let me know the launching  sequence of coolermaster 500w PSUs like MW lite series 500W, MWE 500W, elite series etc !!
