PC stuck in endless loop session.

Hey,

After eagerly receiving my PC today from the repairshop due to this problem (https://www.sevenforums.com/crashes-d...ml#post1838428) I got it back with a new motherboard, the Gigabyte ultra durable GA-Z68XP-UD3-iSSD and I booted up my PC, everything seemed to work but I noticed some flickering on the screens and I assumed it was due to the lack of graphic card drivers so I removed two of my screens, leaving one left and pressed the reset button, it started as usual, however my screen received no signal and after around 20 seconds the PC turned itself off, after about 5 seconds later it turned itself on, this seem to repeat itself as an endless loop.

I'm receiving no picture, my keyboard / mouse aren't lighting up, however my headset does.

I've removed the mobo battery to reset CMOS, didn't help and i've spent the past two hours googling without finding a sollution.
I'm running without an operating system as I just received the PC back from repair.

Any help is greatly appreciated,
Thanks in advance.

I'd pack it up and return it to the repair shop. Doesn't sound like they finished repairing it.

Does it have the CPU cooler installed?

yeh CPU cooler should be there, and returning it to the shop is my last resort. Just got it back after being on repair for three weeks, i'd hate to have to send it back in..

I was able to access BIOS, so I assumed it worked - exited BIOS, turned itself off and went back to the loop.

Think I need to access bios and flush it but I'm not sure how since spamming F8 / del etc doesn't do anything, and I'm not receiving monitor signals.

Update..

Pressing F2 seemed to prevent my PC from going into the endless loop, however, I still have no image so assuming i'm in BIOS, It'll be VERY hard to navigate without seeing the options.

You had multiple displays but unplugged some causing this problem? Plug them back in.

I would take it back to the store and tell them you will wait while they fix it correctly as you have no more time to wait for them, and you need it in a bootable state to fix it yourself.. Be firm but polite.

Wish I could do this. But we're talking about a webshop without an actual store.
Their stock is a long long drive from where I live as well.

I've tried plugging all three displays back in. Didn't work.

Reinstall the video card. If this fails try another video card. If chip, install a video card.

Removed the graphic card and plugged it back in, didn't help.
However it seems like if i leave the pc without the powercable plugged in for a while, the next time i start it im able to reach BIOS with display. However the flickering remains even then so its rather difficult to navigate.

Try setting the motherboard into configuration mode. You'll need all power removed--Including unplugging the cord. Wait a few minutes then follow the instructions for setting the board into configuration mode**. It should boot directly into the BIOS with the BIOS universal video driver. While you're there, if you get a screen, check to make sure no other video devices are set other than your primary. (You can add more later.)

** I tried to get the manual for your board but the site never works for me. The manual will have directions for configuration mode--Usually by setting a jumper on specific pins.

Thats the thing, this mobo doesnt have a jumper.
