Computer restarting loop when i boot up with gpu

Jul 13, 2019 9:59AM PDT

a week ago I had the problem after shutting down my pc if i boot it up again the next day it would just boot up in safe mode n i had to restart it then it would boot up normally then next day the same problem but three days ago i did the same thing this time i got a message that my gpu driver has stopped n it lost signal this Happened two or three times after that it restarted my pc i shut downed my pc then opened up the case n cleaned everything n when i try tu push the power button no response then i had unplug 24 pin from the motherboard n plug it again then it would work fine but my gpu started crashing the moment after the Windows loading screen it starts itself again and again sometimes at the bios screen i get
Artifacts of gpu then pink screen then it restart agian then after 5 or 9 seconds does the same thing with grey screen
N stuck in restart loop with my gpu crashing
I tried turning on my pc without gpu n everything worked fine it works fine
But with the gpu it keeps crashing n wont boot up
I cant identify if the problem is with the power supply or the gpu because my power supply is acting strange
Can someone help me?

You have a few issues in that PC.

1. The 660 is noted widely to need a lot of Amperes. I'll agree with https://forums.tomshardware.com/threads/gtx-660-power-supply-requirements.2076098/ and peg that at 24A. But given the age I want to see the PSU at 50% above that or 36A.

And surprise, this PSU has that. https://www.newegg.com/corsair-vs-series-vs450-cp-9020170-na-450w/p/N82E16817139230

2. The GPU is very old and the signs are here it has failed. Try another GPU.

3. If the PSU is acting oddly I'd have to swap in the GPU first since it's quite the Watt burner and the GPU is so old you will see them at the shop.

Nod to another GPU to test.

PS. While my take is set on this is from shop experience.

There are those that want to try and save the old hardware. At the shop we have to cut off old gear at some point because the clients want (a) it fixed and (b) don't want to bring it in multiple times as we attempt to save old gear.

So with that in mind the usual saves use the following.

1. Software angle. Go get DDU https://www.guru3d.com/files-details/display-driver-uninstaller-download.html and blow out the old driver. My method is to disable Windows 10's automatic driver update (not to be confused with Windows Update) and then install the version driver I know works.

2. More drivers. Update the BIOS and motherboard chipset drivers.

3. Clock everything to safe or stock clocking. If the client is an overclocker make them aware of the store policies (in short we don't support that.)

4. Take a look at the Speccy report for anything that stands out. ALWAYS check the HDD health. High values in 01 and 07 mean you report that as a failing drive to be removed from service.

5. If the machine is past 2 years old, offer a deep clean and heatsink compound replacement. Also you are checking fans here. Fans must work like new.

6. Give the machine your usual assessment. That is you will get some NANO CASE BUILDS which have proven to age parts and be nothing but trouble in the long run. You want to see normal to plus size cases with good ventilation.
