Happens to my recently built Core i5 system.
I have a Dell 19" monitor attached to it. Sometimes displays goes off for a sec and then turns back on.

If my past experience (when I used to have a Pen 4 system) is to be considered, it's not a good sign. And usually means that Motherboard is going to go kaput soon. The reason for this the repair guy used to say is moisture which damages some capacitors.

I have kept my fingers crossed. :Fingerx: :(

this is happening to me also, for a year. happens when any other device - tv/fan/tube/else is switched on or off, because of the little voltage fluctuation that occurs during switching.

i think somewhere some capacitor probably isn't working as it should, it could be either of psu/mobo/gfx card or the monitor itself. or it could be windows 8 issue, not sure.

what brands of those components u people are using ? mine are corsair gs600/asus g41 mobo/evga 560/dell 24" - anything there seems common with what u ppl have ?

Holy ***.. Same happened to me i have same i5 Rig....
as well as R9 280x..... but my problem was due to the game itself, while playing a game the display went off for 2 sec and came back on showing AMD Display driver has been recovered. but when i stopped playing that game it never happened to me....

I had been facing this issue for some time with my Dell monitor connected to the laptop via HDMI. Whenever I switched off/on anything in my room, the display went off for a second.

Then I got a UPS and connected the monitor, the speakers and the wi-fi router to it, and everything has been working fine since then.

Its just earthing problem. Sometimes everything in the cabby also gets fried.

thanks for the link. i am using a cheap hdmi cable, cause monitor doesn't have dvi port, even though i have those from my old monitor.

may be due to the cheap cable, not sure. are u all using cheap cable too ? (we don't have any earthing prob, earthing is ok)

200 buck clable is most probably cheap chinese unbranded cable. that can not be good cable.

idk, let others recommend. but it may be good cable, if these flipkart reviews are legit, and these ppl are actually using this cable without any issue..... (however, u need to check the hdmi port types u need - mine uses mini hdmi to hdmi cable -etc)

so which cable to buy? plz suggest..

not like that...
a bad cable you have has improper sheilding thats why it is picking interference from nearby high voltage wires(230v ac) and disrupts the digital signal and we get a blank screen

change cable this is the sure solution and nothing related to earthing.


i too use a 200rs cable but it is a good one,
recently gor a 10m hdmi 1.4v cable and no issues, because it is a good cable.

only what you can do is try all the cables you have...

I also tried hooking up a wire to the computer and putting the other end of wire in the wall with a nail..but tat didn help either..still got current running thru the cabinet..

are you getting shock when you touch cabby?
then it is sure a earthing problem...

that "wall" will not be a good source(maybe the nail didnt conduct properly...) to bring the cabinet volatge to a neutral level...
cal your electrician, he will check if there is earth wire in your switch board and check with a incandiscent bulb if it is working or not.

or else get a new earthing done(hole in earth and copper wire, blah blah...)
many be the apartment should do for you if youre rented... its their responsibility
earth failing could be hazardous in some places(washing machine?)

what cable u bought ?

what cable u bought ?

weill i have 5 hdmi cables now...
2- the ones with that cool-looking fiber/plasctic wound on the plastic pipe(which covers the bare wires) are performing well.
2- oridnary black cable one is performing bad (sreen blanks if anything in the house is swiched on.)
1- got a 10m just 2 days back.(whith that cool looking thingy and it is also good.)

these are based on my experience, i dont say that the cool looking cables are extremely good approved cables.

if there is current running thru the cabby does it mean current leakage / a faulty smps? ?

no all computer have some current flowing like that...
even my corsair(x2) and a zebronics(x3) one did the same

I had the same problem at home with a dell monitor. We swapped hdmi cable with dvi and problem was solved..

The funniest thing is...
My friend works in an mobile app development company as a UI designer.
The designer group sits in a common area and using 24" dell monitors...
They have switches for lights...
And the same flickering happens on most of their monitors if someone turns on/off the switches..
