Hello, I have had this ongoing problem for a few days now and am trying desperately to fix it. When I am on the computer it reboots, and sometimes when it boots there is no display/keyboard/mouse. I haven't been able to use the PC in days without it rebooting almost immediately.

PC specs:
500W Cooler Master PSU
560ti gtx GPU
Intel i5 processor
1TB HDD
8GB RAM
Gigabyte GA-B75M-D3H mobo


I have cleaned out the computer, reinstalled the OS, and all the fans are running. When it boots to no display it also lacks in powering the keyboard and mouse, but does not reboot when it is in this state. Maybe a bad PSU but I don't know the minimum wattage needed to power it. I have a spare 450W I can try if that is enough.

Thank you to anyone that helps.

It sounds like a failing psu... swap them but if you can. If everything is as normal go about getting a new psu. Of reputable make and quality.

Well I had to hook up the 450W psu to the motherboard, HDD. Then used my 500W for the GPU, and since I split the load it runs fine. So I will have to get a new psu, probably a 600W because I am planning on upgrading it soon anyway. Will let you know if the problem occurs again while in this new setup

You guys are the best, thank you again!
