content: Please help me, I bought a new video card for the PC, installed it, turned on the PC and when I started playing after a few minutes it stopped working there is no video, when I had an R7 360 sometimes it stopped giving video so I put it back and the video came back but this new card is a Zotac GTX 1650, my PC config is Antec HCG 520 source, third generation i5, 8gb of ddr3 ram, gigabyte motherboard GA-H61M-DS2 rev 1.0 what I found strange is that in the contacts of the board I saw this detail but I don't know if this is related to the problem, I put isopropyl and rubber and clean the contact and it didn't remove it

content: A lot ca be bad...First question with these several watts cards is about the psu.. if the psu is shitty the pc will just go adhocSecond is having all sort of bench equip to duplicate symptoms with different hardware...Paul

OR... the card has some solder issues when hot...Paul

content: Consider that you may have just gotten a bad card. You say it was bought new, so contact the seller, explain the problem and negotiate some kind of acceptable settlement. They should just simply replace the defective item.

content: i would go with that possibility *IF* the card fails on any other MOBO...As long as it works with other system...and the MOBO has a working IGPU.....other options should be on the table...Paul

content: No.. never..You need some external devices to measure this.. not simpleExternally you can even use these "AC Power meters adapters"to check dynamic outlet power draw...But with GPU the bottom line is way below this..GPUs putsurgesandspikeson the PSU..They are very fast and can cause the REGULATION TO FAILand a fast drop fo the voltage which is hard to see with common instruments..but the CPU may reset or even halt on some of these drops..Oversizing PSUs was ever a simple but expensive and unreliable solutionCrypto-mining setups use 2 or 3 PSUs one for each GPU to avoid resets on HIGH current spikes..Ultimately you can not see this surges (i posted a very good explanation from IGORs LAB about this.. somewhere... ) unless using complicated measures...The BIOS can only setup simple things like turning OFF iGPU (less power draw)Under clocking the GPU... less power draw..But this is not solution.. you need power +a separate connector..get rid of the PCI lanes 75W limits....a power hungry PSU...GPUs as of today are insane power devices..You need to compare the best affordable solution..**IF** your card is working but you have lack of power for it..but...if the card is bad with thermal bga problemsthey will manifest on other mobos...PaulPS forgive me if this is not the topic.. i just made a fast search of an old issue..https://www.igorslab.de/en/power-recording-graphics-card-power-supply-interaction-measurement/
