Pc Keeps Restarting On Bios Screen Please Help!

[dianespiegel25]

Hi all, i’m having this issue where my computer is stuck in a restart loop. I switch it on, it loads to the bios screen where i can press f12 etc and then it restarts and does the same over and over. This has happened out of random as my computer was working fine last night. I am able to access the bios settings, and while in bios the computer doesn’t seem to restart. I have tried reseating my ram, unplugging my gpu and starting the computer. I am also unable to start my pc from a windows usb, thr computer just restarts as soon as i turn it on.

Specs:
i7-7700k
Gtx 1060
Corsair 16gb ram
550w Corsair PSU
And an gigabyte z270-gaming k3 motherboard

If anyone would be able to assist me that would be amazing, i can’t believe this has just happened as my computer was working fine yesterday. Many thanks

I would try removing all USB devices and restoring default settings in the system's BIOS-see if that makes a difference.

sounds like an issue with OS/HDD/SSD. you are booting to bios which is good, are you using an old storage drive?

 

[dianespiegel25]

@norcalsc i am using a old hdd yes, however my widows is installed on a ssd. I unplugged them both and tried to boot and the same thing just happened. @greeko85 i tried this and nothing seemed to work, it’s still stuck in the loop

Try installing just a single ram stick, perhaps try multiple slots as well, clear CMOS by fully draining the system/removing battery etc and try again. Out of question you don't use any software that auto adjusts things in your system such as overclocks on cpu/ram?

@Greeko85 thanks for the fast responses and i tried to reseat ram, single at a time as i only have 2 sticks and that didn’t work. I reset the cmos 3 times and still no hope. I had RamMap on my computer and recently i had to clear the standby ram as a game i was playing suffered from memory leaks and this helped with crashes, other than that no.

@greeko85 is there a chance it could be my psu? However the computer doesn’t turn off when in the bios f12 config it stays on, would that rule out the psu or not.

 

[Greeko85]

It could be the psu but as you mentioned its stable in BIOS so it kind of makes me feel like there is something else going on.If you do have access to a spare one its worth trying it out though.
When you are in the BIOS menu do all your specs check out ok-cpu/ram with appropriate speeds? Do you know what BIOS revision you are running? Maybe try flushing a newer version in the slight chance it magically resolves something? I am literally out of ideas at this point. I have had systems do "special" things like that over various reasons-one was resolved by replacing the cmos battery, I dont know why it fixed it or it was a stroke of luck but it worked :/

@Greeko85 all my specs seem to be running fine and it says i am running bios version f8 how would i go about flushing a new version? I have a gigabyte motherboard

 

[Greeko85]

You'd need your exact motherboard model-sometimes its mentioned in the bios otherwise crack your side panel and have a look as most of the times its printed on the actual board itself (usually around the PCI-e slots). If you get stuck take clear photos of the board and post them here-I'm sure someone will be able to pick it out.

My model is the gigabyte Z270-Gaming K3

You'll need a working computer so anywhere like a mates house/spare pc/library etc.
This is the bios download location:

This is gigabytes tutorial for flushing new BIOS on their boards:

Long story short you will need a usb stick-I prefer to use a small one (2-4gb) formatted at fat32. You unzip the download file and copy the file on the root directory of the usb stick. It will probably be something like z270.f9d or something similar. Put the usb drive in your system, boot and enter bios. In bios you should see an option called Q-Flash. I haven't played with gigabyte boards in a while so my memory is fuzzy but you should had options to update/flash bios or copy bios etc. You want to update. It will ask you to select the directory, select the usb drive and then the file that matches your mobos model-in your case the z270.f9d (I'm guessing thats what the file is called). It will ask you if you want to flash with the selected file, say yes, probably some warning prompts as to not interrupt the system. Follow the prompts, let it finish and it should reboot. Keep your fingers crossed and hope for the best.
