Solved PC (new build) not booting to bios on monitor. How to fix?

April 25, 2019 at 17:22:53
Specs: windows 10, AMD Phenom II - list of components

When computer turns on, nothing pops up on the monitor so I can boot into the bios. The computer starts with fans running fine, no error beep. Lights are on on the motherboard. I have tried...

-Made sure CPU was seated correctly
-Changed out the sticks of memory (tried each in the first slot)
-Tried 2 different graphics cards

-Made sure monitor was on correct display
-Tried display port directly into monitor (with graphics cards out)
-Tried another monitor
-Tried changing out the memory sticks in every slot

Any help would be appreciated! (24 pin seems fine, I assume the CPU can go in either 8 pin? GPU and sata doesn't matter at this time. pins seem fine appears to be mounted okay overall view, motherboard lights are on, fans are running. Can get better picture if need be.

Try/borrow a HDMI cable & test.

✔ Best Answer
Make sure CPU 4/8 pin connector is correct connector, not 6/8 pin PCIe connector.
Try removing plugs from hard drive/SSD drive.
Try only one memory stick in first slot.
It is possible too much thermal compound, review and reset.
Remove all components except 1 memory stick, keyboard, mouse, monitor to onboard graphics (preferable VGA or DVI cable if possible).
Check that all stand offs to the case have screws in them and there are no extra stand offs under the motherboard where no screw holes are in motherboard. Look for stray lost screws that might have slid under motherboard. (better yet remove motherboard from case and place on clean cardboard).
Check that no wires were pinched when routing them in case.

Are you an experienced builder? Did you bench-test the hardware before installing it in the case? That's an important step that many 1st time builders skip.

How to Bench Test

Take out the graphics card & connect the monitor cable to the motherboard graphics port. Unplug the mouse but leave the keyboard connected. Disconnect the SDD, both the power & SATA cables. Do the same for the optical drive (if there is one). Remove all RAM except for one stick. Make sure the HSF is mounted securely & that you applied the thermal paste correctly. The i7 uses the vertical line method of application. If you did it differently, remove the heatsink, wipe off all the paste, then reapply paste as shown: Do not spread the paste!

After doing all the above, try booting & see if you can access the BIOS. If you can, run thru the BIOS menu & tweak the settings accordingly. Be sure to save the changes. Reboot again to make sure you get a display on the monitor. If all seems well, shutdown & begin reconnecting things a little at a time. Don't do everything at once because if you run into another problem, you won't know the cause.

And before installing an OS, test the RAM with memtest86 or memtest86+.

EDIT: I just saw the picture with how you applied thermal paste. That's probably the problem.

It does appear you applied way too much thermal paste. What brand paste is that anyway? I have never seen brown paste.

"What brand paste is that anyway? I have never seen brown paste"
As per the op's specs.

"no beeps on boot" Is there a speaker attached to the MB?

Page 30 in your manual, shows where the buzzer speaker connects.

memtest86 is the better one.

memtest86+ hasn't been updated for 5 years.

If that is a picture before the mounting, like riider says, that could be the problem.

shouldnt the 212 evo be rotated counterclockwise 90 degree? (2 fans facing eachother)
also please dont forget to place the 2 memory ,modules in config A0+B0:
else you cut memory bandwith in half, which can hurt CPU performance quite a bit
