Black screen when starting pc.

[Aygun_Ibryamov]

Hello guys,

Yesterday i opened up my case to clean my cpu fan and abit inside of the case. I did not use a vaccum cleaner or anything wet. What i did use were some (ear brushers?). After that i put everything back in its place. (CORRECTLY). And then when i tried starting my computer. Cpu fan started spinning just like normal but then the pc made a strange beep sound for like 2 seconds. (never did that before) and i have no signal at my monitor ( i have checked hdmi cable is plugged in). I dont know what to do. Check also the video i put on thats the video that i made.


Pc info:
Intel i5 4460 3.20GHz
nVidia GeForce GT705 1GB
6GB RAM
1TB HDD
240GB SSD
Motherboard I dont know
PSU: FSP Group INC, Model : FSP300-60EP (1)

Also an add if my gpu is f*cked up. Which i think it is. Can my psu handle a GTX 750 or a GTX 750ti?

Thanks in advice, Aygun

Hi there @Aygun Ibryamov and welcome to PCHF

Do you have onboard graphics? If so, have you tried connecting to it and seeing if you get anything on the monitor?

Hi jmarket

What do you exactly mean by onboard graphics? I have a gpu inside. nVidia geforce gt705 and its connected from that gpu with a HDMI cable.
I see nothing on the monitor only black screen

@jmarket’s suggestion I believe was to rule out the add-on graphics card (the gt705) as a potential culprit and use another.
if your motherboard as an on-board graphics card (built into the motherboard), there will be a VGA, DVI, HDMI or DisplayPort connection on the back of the PC where all the other peripherals are plugged in. Try using one of those display ports (with appropriate cable and matching port on the monitor) and see if anything changes.

Oh now i get it. I think i saw a VGA port behind. But there was a cover on it which i tried removing but couldnt.

So if my GPU is the problem. What GPU would you guys recommend me? I have a FSP GROUP INC power supply. Model FSP300-60EP(1)
Budget around 130euro. Im thinking about a GTX 750ti or a GTX 1050? What other choise are available?

Just to add an important step if you want to try your onboard graphics. Make sure to take the Nvidia GT705 out of the machine first.

Hello guys, thank you for all your answers. I was a little dumb while putting the ram in. I pushed the ram but i didnt lock them with the locks that they have at the edges. Thank you for you answers again.
