So i have just built my first pc and i tried to boot it up. It turned on and the fans are spinning, but it wont boot and i wont get any beep. So except from that i tried shuting the system down by the power switch but nothing would happen and the light and fans would be still spinning. So i had to cut the power. I know that there are similar "wont boot" threads", but im curious about the " wont turn off" issue.

Im pretty phreaked out and i dont want to mess up on my first time.

Please reply as soon as possible.

Is the CPU power connector plugged in? It should be four or eight pins and is separate from the 20 or 24 mobo power connector.

yes it is and i just disconnected and re-connected it . Actually the one i am worried about is the fact that it doesnt turn off through the power switch. I cant try out solutions cause im afraid that the systems will get damaged if i keep cutting the power to shut it down. Could it get dmg if i keep doing this?

Do you get the BIOS splash screen, or is it just a black screen?
If it is a black screen, is the monitor connected to the motherboard or a graphics card?
As for not turning off, double check the connections for the front panel connectors. Does the reset button do anything?

yeah it is a black screen and yes the monitor is connected via vga to the graphics card.
No the reset does nothing too. i will check it again, but if they werent connected correctly then how did the system turn on with the power switch in the first place. Again, will cutting the power to the system to turn it off affect it in any way? Cause i dont want to try things and if it doesnt work shutting it down that way. Thanks for your responses btw.

I had a system that would do this when under load; screen would go black and nothing could restart it, short of pulling the plug. In the end, it was the graphics card. I was just trying to eliminate the easy, cheap fixes.

Well i will firstly check the front panel connections for the power switch and then try things up. If you have any other idea plz tell me.

If you have integrated graphics, you could see if it will work on that, which should let you know if the graphics card is the problem.

Well i disconnected and reconnected the front panel connections 5-checked the manual. I guess ill wait for a solution on this thread while i keep searching the web for it, cause i dont wanna risk anymore with all these "cut the power off"s. Please any1 that has a small idea or proposition of how to deal with this, feel free to answer.

I mean that, if possible, you connect the monitor to the motherboard and remove the graphics card before trying to boot. I understand your concern about damaging the system, so it might help if you could share a few more details about your rig, such as motherboard, CPU, GPU, storage configuration, case, ect.

When you say the fans are spinning, exactly what fans do you mean? Are you talking about case fans, and, if so, are they controlled by the motherboard or just hooked to the PSU or a fan connector/controller? Is the fan on the CPU cooler spinning? What about the graphics card, does its fan spin? If we can figure what is working and how it's working, that would go a long way towards finding a solution.

How can i connect the monitor to the motherboard? so my build is :
AMD FX-8150
asrock 970 pro3 R2.0
G.skill 16gb ddr3-1333mhz dualkit
Asus GeForce GT630 1 gb
Corsair cx 600
western digital caviar green desktop 2tb 3,5"
Case : Sharkon T5 midi atx case economy edition
water cooling: cooler master seidon 120m

By fans i mean the fan of the watercooling, the fan in the front that came with the case and the graphic card's fan. All of the fans are hooked to the motherboard and all of them are working pretty well.

Perform this steps, if it still doesn't work you have most likely a dead part. Sent in my motherboard 2 days ago


Thanks for your answer mate. I have already seen that website and im sure its very helpful, but i cant try all these steps if i cant turn off the system properly.Feel free to suggest anything else you can think of.

Unluckily, i think its the only way to figure out what's wrong, I also could turn down my PC with pressing the powerbutton for 5 sec, so that the system stops
