Black Screen and 'No Signal' Issue on Intel Core i5-2400, NVIDIA GeForce GTX 550 Ti PC

Hello, I have had a problem with my computer for some time. Well, during normal use, suddenly the monitor screen turns completely black and the word "no signal" appears for a few seconds. I was moving both the cable and the monitor inputs and nothing is happening at all, but rather it should. In addition, even the "reset" button does not work, so the fault is probably on the computer's side, but what exactly?

A little edit because I entered false information. "Reset" on the computer works, while I was talking to my friend on Skype and pressed reset, we disconnected, I have not seen it before because I did not see what is happening on the monitor.

My spec:

Intel Core i5-2400 3.1GHz
NVIDIA GeForce GTX 550 Ti 1024MB
10GB RAM (8 + 2)
Thermaltake Smart SE Modular 530W power supply.
Main board GA-H61M-S2PV

What's the problem?

First, replace the power supply.

At the beginning, however, I would review the system log. It looks more like a problem with the graphics card to me. Maybe there will be an entry that the driver has stopped responding, maybe a different one. Only those entries that appear at the time of the problem are meaningful.

Power adapter not necessarily. I'm betting on a problem with the graphics card. The information you provided shows that the monitor is not receiving a signal from the graphics card - hence the black screen and the "no signal" info.
Try to replace the card with another one, you will have a quick diagnosis of the problem (or rather its confirmation). As a warranty card, it is nothing but to send a complaint.

At the beginning, do not change anything. The gentlemen probably did not pay attention to the fact that the author of the topic has integrated graphics in his album.

Pull out your GeForca card, plug the monitor plug into the integrated output on the board. Fire up the system and try to fix your fault. If you can't remove the card, maybe in the bios there is an option to disable the PCI-E port or give priority to the image for the slot on the board

Good point :)

Also, check if the video card selection in the BIOS is set to "Auto". If so, then after removing the graphics card and plugging the monitor into the socket on the motherboard, the image on the monitor should appear (assuming that the monitor, motherboard and integrated graphics card are working properly).
If, however, in the settings the graphics card in the PCI-E slot is selected as the source, it should be changed to "Auto" or to integrated graphics. Correct me if I'm wrong.

If the source is PCI-E it won't even fire to change it to Auto. It is best to reset the BIOS after removing the card

Maybe I'll start from the beginning. I set up the topic on Tuesday and the symptoms were the same, ie 15 minutes came, then "no signal". I turned on my computer on Wednesday and it was going from 1pm to 11pm and it didn't even hesitate to turn off just as if nothing had happened. Today he has outdone himself. From 9 am until now I tried to turn it on. It worked only after a "hard reset" of the system, such a white line was flashing on the black screen and the computer would not turn on. The format helped, but the "no signal" problem persisted. I checked on 3 different cables with D-SUB inputs, and on the TV to rule out the fault of the monitor, it was the same everywhere. Only after reading the post "avy215 "I actually remembered that I have it in the disc integrated integrated card. I unhooked the card, connected the monitor to the motherboard and comp the computer has been running for an hour.

The strangest thing is that in the meantime I took the "can" to my friend and for 2 hours he had a computer with him, normally connected to the graphics card, and I came home and "no signal". Well, na integrated integrated for now, but am I 100% sure that the fault lies with the card?

At this point, however, I would be inclined to blame the power supply.

You are not 100% sure because there is also a power supply. After all, I bet on the graphics, so I suggest replacing the graphics from my friend, and even attach yours to him. You will not make a mistake, and he will have 100% that it is graphics.

This is a bit of a home method, but I guess you don't have other conditions

The above makes sense because the substitution of poor graphics will not exclude the power supply from the group of suspects.

I will do it tomorrow and let you know. Damn, the power supply would probably be the last thing I would suspect. A good brand, a sufficient amount of WAT and in addition it was bought a year ago, new.

Edit. On the other hand, when I brought the fluff to a friend, we didn't do anything other than just plug the computer into his monitor and it worked. On this card and this power supply.

Well, there is still the question of the quality of your electrical network. Is the voltage in the socket good, stable and the grounding pin is present and connected? Or maybe you have some peripherals connected to the computer that you did not take to your friend?

I didn't take to my friend only the microphone attached at the back and the headphones attached at the front. As for electricity, it's hard for me to say, I don't know anything about it, but it seems to me that everything is fine, I have never had any problems, especially since when "no signal" appears, the computer is active, there is no image just . Oh well fan the fan from the graphics card somehow goes faster and louder.

Take the test we will think further. Looks like a problem with the card again ( fan the fan changes the form of things) but if the card has a bad power supply, it will also crash. And so we go around.

I took the computer to my IT friend, he "played" with it all day to check everything thoroughly. He checked all the combinations (e.g. my card on his motherboard, my card in his computer, his card in mine etc.). The power supply checked with a meter and also said that it was good.

He told me that it was the card's fault, because after he put my card into its configuration and tested it with 3DMark, "no signal" was also popping up on the monitor.

That is 99% of the card. I'm just afraid that when I order a new one, after inserting it into the computer, it will still be "no signal".

Not 99% but 100% it is a card, buy a new good company

I want a new one, I have a bad approach to used cards, and since my budget is close to PLN 700, the only option is probably GTX 950. What do you think about this MSI card?

It's best to google different card tests. At the beginning you have to answer the question "what do you want to play" - check the optimal graphics requirements for a given game and enter its parameters in the search engine.

Good card test sites always provide price / performance ratio, suggest optimal solutions, etc. Not every GTX950 is equal to a third-party GTX950, sometimes an older and cheaper card model from a given company is better / more efficient than the newer ones.

You can also set up a new topic on the electrode, there is an advice section here
