Solved PC Reboot cycling, no display connecting.

April 13, 2016 at 09:07:56
Specs: Windows 7
Basically been working on it for a few hours, I have plugged in a working PSU and HD to check if those were the issue. Everything continued the same. It is a custom built computer that randomly restarted last night and has been cycling its boot phase repeatedly since. After it cycles about 3-4 times it will stay on (ie: fans continue to spin, CPU/GPU spinning etc) but will not give a video feed to a monitor. I will mention we had a storm last night and the computer was plugged into a pretty sturdy looking surge protector we got from AT&T with internet. Im just looking for what component this may be so I can replace.

✔ Best Answer
You gave us very little to go on. Please post your complete system specs. Are you hearing any beeps? Do you have a case speaker connected to the board?

To troubleshoot, disconnect ALL the non-essentials. Unplug all external devices except for the keyboard & monitor - no mouse, internet cable, printer, external drives, etc should be connected. Internally, unplug all drives (DVD, HDD) & remove all but one stick of RAM. If you have a video card installed but your board has integrated graphics, connect the monitor to the onboard port & remove the card. The idea is to lighten the load & eliminate as much hardware as possible. After disconnecting the above, try booting the system...if you can get a display, enter the BIOS & double check the settings. While you're there, check the CPU temp for overheating.
