Solved Boot Loop--No POST or Display

[TONPumper]

Last night, I played a game and when I exited the game normally, Windows came up with an error stating that the program closed unexpectedly--which it didn't because I was the one who closed it. I ran Wise Disk Cleaner and Wise Registry Cleaner after I did an update on Windows 7 just to clean out some junk files and see if that would help the game. I didn't get a chance to play the game again after I cleaned the system since it was late. I went to bed, but during the middle of the night, my computer monitors came on without me doing anything to the computer (moving the mouse, touching the keyboard, etc.) so I got out of bed and forced the displays to sleep again. Later, the same thing happened with the displays, so I shut down the computer all together. When I woke up, I tried to turn on the computer, but it wouldn't boot into Windows. The lights on the case came on but there was no display. The lights would come on, then go off again after a second, then it would come back on again with only the lights and no display. I flipped the power switch in the back and opened the case to see if any of the cables were loose. I checked a hdd cable and the gpu cable, which seemed to be okay. I flipped the switch in the back and turned on the computer with the case open, and I noticed that the back fan on the system did not turn on. I wasn't sure if this would prevent the computer from turning on or not.



This isn't the first time that this has happened, in regards to the system not booting and only showing lights. When I installed my SSHD and went to boot the computer, I had the same issue with the lights coming on but no display. I just reseated all of my drives and that seemed to fix the issue. I just don't understand why this is randomly happening. I fear that there might be a shortage somewhere, and I'm hoping it's just one component that's shorting out.

Hi TONPumper,

Try this:

HP Desktop PCs - Performing a Hard Reset

Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a "Hard Reset". Use the following steps to perform a hard reset on a computer:

1. If Windows is open, click Start and then Shutdown.
   If Windows is not open and the computer has power, press and hold the power button on the computer until the computer shuts off.
2. With the power off, disconnect the power cord from the back of the computer.
3. With the power off and the power cord disconnected, press the power button on the computer for 5 seconds. The power light indicator on or near the power button might turn on briefly but then go out.
4. Reconnect the power cord and turn on the power.

Tried this, same issue. Also tested all of the ram sticks and tested it without the graphics card. Some people were blaming the psu.

Do you have another PSU you could swap with?

Are you overclocking?

I don't have another psu to try. I overclocked my cpu from 4.2 to 4.5. Could that be the problem?

Try running HeavyLoad - Free Stress Test Tool for Your PC - JAM Software
You can stress your CPU and GPU separately or together.

Did you have your issue before you overclocked?
If not, maybe. Try resetting it to default. If no more problems, yes, that is your issue.


On one of the other threads regarding BSOD, OP's solution was to install a program OP had running, uninstall it still had issues, I suggested OP reinstall it, and uninstall with a dedicated uninstaller, SevenForums recommends Revo Uninstaller, which I use.
OP still had issue, only less often. Solution was to underclock CPU slightly.

Issue ended up being the motherboard but instead of trying to find the same or equal model, I'm just building a new computer with updated parts.
