New Build: Boot Loop Before Getting to BIOS.

**UPDATE** I found out that it was one of my 4gb memory sticks. The mobo was giving me a code of 55 which means "Memory Not Installed". I took it out and runs fine with just the other stick. No matter where I place it or what combo, I get the boot loop. Does this mean that I have a bad stick and should request a replacement?


Yesterday, I built my first computer from scratch. After spending several hours getting everything plugged in, I booted it up and was able to successfully install windows, several drivers for the mobo and GPU driver. I decided that I would let it run overnight to install the various programs games so in the morning I was ready to play. However, I noticed that it was in a boot loop. It computer would turn on, all lights on the GPU, Mobo, Case seemed to work fine but the monitors wouldn't get a signal and I never saw the BIOS screen ("Press F2 for Boot Menu" etc), then it would turn off for about 3 seconds and then try again. I had to switch off the power supply because holding the power button didn't work.

I'm new to brand new system builds, so I am not sure where to start. There was no beeps or unusual sounds coming from the computer. I unplugged the GPU from the mobo, but it still had the same issue.

My concern is that I maybe installed the CPU cooler wrong, or put too much thermal paste and it spilled over and could have damaged the CPU. It's just weird that on the first run I was able to get everything going, and even did several reboots when installing drivers but now I can't even get to bios. Can some one please assist me on how I go about determining the problem?

These are my specs:

Some of the solutions get quite involved. Search "Windows boot loop" and you'll get many hits with detailed instructions.

There may now, however, be another problem since you were forced to shutdown via the PSU switch. I'm assuming you are using the SSD for quicker booting. There have been problems with SSD's and unexpected power loss like the one you did. See the following article.

I tried searching for Windows Boot Loop previously, but all those solutions require me to access Windows Repair or BIOS which is something I can not do.
