Strange problem in Philips 202EL2SB/94 ,20" LED monitor

[kg11sgbg]

Friends,occasionally I see a peculiar problem going on with my PHILIPS 202EL2SB/94 LED(Backlit) 20" Monitor.
Everything in display is fully normal,except sometimes a click sound is heard and within the single second,the Monitor Blanks OFF,but again returns to normal to the same display page,functions,without any sort of alteration or distortion.
Everything seems to be running the same as it is.

What kind of problem?

Why it occurs?

Any solutions?

do you have a gpu?if yes have you tried switching to onboard graphics?

^Yes recently bought a low budget GPU from Zotac,the nVIDIA GeForce 620 1GB DDR3 Synergy Edition.

I am not a gamer.

My Motherboard is : BIOSTAR TA785GE 128M ,which has an IGP (ATI/AMD 4200) HD Radeon Graphics.

But the IGP is disabled from within the BIOS.

try with IGP and I used to have such issue barring the click sound - just changed the spike guard.

Thanks topgear.
Actually ,the power chord of the monitor is attached with one of the plug socket of the UPS.
Any problem regarding this?

if possible [ just to test ] run the monitor from main power socket avoiding the UPS just to see whether this issue gets solved or not.
