My pc turns on for like 10 seconds and turns off, all I did was remove my gpu to clean it. I should also note that when it does turn on, there is no signal. Everything is plugged in. This happens without the GPU plugged in also. my pc is from cyber power and the gpu has a sticker on it saying " warranty voided if removed" could they intentionally be doing this since I removed it? Could the power supply have just crapped out and this is a coincidence? I need help bad!!

Your OK with removing the GPU from the system, just do not remove the sticker from the GPU. This is all that the sticker means. It is to prevent people from opening the GPU and causing damage to it.

It sounds like there BIOS is not getting through its POST (Power On Self Test). Certian manufactures of motherboards make them do different things when the POST fails. Some will try to boot three times, then revert the BIOS settings back to default and try again, IF it is unsuccessful it will then turn off. Others will try to boot and if it does not it will bring up a screen saying the overclock attempt failed, even if no overclock was tried, making you enter the BIOS and fix the issue.

In your case it sounds like there is a hardware issue causing the BIOS not to pass POST. Because you were in the system just before the problem happened try the basic things first like: Remove the Ram modules and reseat them making sure they are installed all the way, Insure all the power cords are properly plugged in all the way including the GPU, make sure the GPU is seated all the way in the slot, make sure all SATA cable ends are plugged in to the devices and motherboard properly.

after this is done, Testing after each thing is checked, then you move on to hardware testing. At this point it would be best to get a case speaker that give the trouble code in beeps or if your board has one look at the digital readout code. the trouble code will tell you what component is causing the issue. Try the GPU in a different machine to be sure the GPU is in working order.

Be sure to ground your self before you put your hands in the PC, touch the case or the PSU to discharge the static your body may hold.

Everything is definitely plugged in all the way, especially the gpu since it's the founders edition of a 1070 and the green letters on the side that say " GeForce GTX" light up. I don't have any means of trouble shooting any hardware defects or another pc. I thought it was the pus since I just removed that to fin A LOT of dust, but it still happens after I cleaned it :(

Make sure the EPS connector is plugged in, it is a 4 pin or 8 pin connector )depending on your board) near the CPU. Double check the 24 pin main connector to be sure it is connected tightly and all latches are locked on all connectors. if the PSU is modular make sure all connections at the PSU are connected properly also. Make sure the PCI-E 8 pin connector for the GPU is latched. The GPU get power from Bother the motherboard and the PCI-E connector so the lights coming on does not mean much.

what motherboard is installed? make and model please

Boy do i feel dumb. Apparently the ram sticks were not in all they way which was causing my pc to turn on an off. No, im not sure how this happened since i dont remember touching them. Hopefully this helps others that stumble upon this thread and learn from my mistake.
