Dibya Posted December 19, 2019 Share Posted December 19, 2019 (edited) I installed new power supply to my pc . Here are specs, Intel core i7 3770K Kingston hyperx 8GB 1866MHz RAM X 2 Gigabyte GA-H61M-WW motherboard I installed new power supply and processor . When I turn on computer it asked me to save bios settings to default and I did that . After that when I click power switch it , the fan spins for few seconds and then turn off. After that when I reset bios, I entered bios settings I was seeing if their any wrong settings , the system suddenly turns off in between while I was browsing bios settings. Please have a look https://ibb.co/HNQp3Sm https://ibb.co/qNx1dcG Edited December 19, 2019 by Tripredacus Link to comment Share on other sites More sharing options...
LoneCrusader Posted December 19, 2019 Share Posted December 19, 2019 I would think the system would throw an error beep or some type of notification if it's not connected; but - is the 4-pin CPU power connector to the upper left of the CPU connected? I can't make it out clearly in the picture. Link to comment Share on other sites More sharing options...
dencorso Posted December 19, 2019 Share Posted December 19, 2019 Update the BIOS to the latest available. You'll need a low end Sandy Bridge to do it, preferably an i3. Your issue is lack of BIOS support. Link to comment Share on other sites More sharing options...

Your issue is lack of BIOS support. I have one spare G2020, the board support that chip . I will update the bios and inform back. Link to comment Share on other sites More sharing options...

I just couldn't see if it was connected. Since one appears to be loose looks it looks like the power supply provides double 4 pin connectors which are required on higher-end motherboards like the X79/X99/X299 and probably others.

Tripredacus Posted December 19, 2019 Share Posted December 19, 2019 Dibya, you've been a member here long enough to know to create better topic titles, and put topics in the correct sections. Renamed and moved. Not having the 4 pin connected won't allow the system to even get to the input stage. Having to reset BIOS default on a new CPU install is normal. The system powering off while in setup is not normal. I would check for grounding issues. Make sure all of the screws are in the board, and no extra stuff floating around in the case. Also that the case is not touching anything conductive. Seems from the picture that it is on a floor on its side (unless that was just for a picture). If you are operating it in this way, you can put wood or a book under it. Link to comment Share on other sites More sharing options...
asdf2345 Posted December 19, 2019 Share Posted December 19, 2019 I think the PSU might be giving out too low or high of a voltage, try the paper clip trick, and use a multimeter to measure the voltage Link to comment Share on other sites More sharing options...

Dibya Posted December 20, 2019 Author Share Posted December 20, 2019 System may not turn on due to thermal throttling ? My mom successfully entered bios and it is throttling badly. https://ibb.co/3Ymyvyt Link to comment Share on other sites More sharing options...
Dibya Posted December 20, 2019 Author Share Posted December 20, 2019 (edited) Reapplied thermal paste and it is running flawlessly Edit : Moral of the story , don't cut cost on thermal compound , I used Artic MX-4 as it is safe for PCB as it doesn't conduct electricity Edited December 20, 2019 by Dibya Link to comment Share on other sites More sharing options...
