Why GPU only works when BIOS reset, only for 2 minutes?

April 30, 2017 at 13:42:49
Specs: Windows 10
thanks for reading.

First my specs:

AMD fx 6300 six core 3.50ghz
8gb of RAM
Windows 10 64
Gtx 660 zotac
Gx bronze 650w
Motherboard: ga-78lmt-s2
Hd 500gb

this setup worked fine for me for 3 years.

My PC only starts with the on-board graphics,the 660 outputs nothing to the screen,to make the 660 works i need to remove the motherboard battery to reset the bios,doing a short with a screwdriver don`t seen to work {the PC stars in boot mode,but not the 660},after doing the thing with the battery the GPU works fine outputting signal,but after 1 or 2 minutes the PC restart automatically,now only working the on-board graphics,to make the 660 work again i need to do the battery thing again,but it will only last for 1 or 2 minutes again. this problem has persisted for 2 weeks now.
any idea what could fix ?
thanks in advance.

Disable auto restart so you can read the error message/s. See the first link below to learn how.

I suspect your system is overheating or your power supply is failing. To check those items download and install HWMonitor from the second link below. You can read the voltages and temperatures in real time by running HWM in the tray. The +12V, 5V, 3.3V should all be within +-5% at all times. Post the temperatures here.

If you remove the video card and just use on-board graphics does it still reboot?

Check the card's heatsink and fan. Are they free of dust and is the fan spinning freely?

In general, to reset the cmos you don't need to remove the battery. Locate the 'clear cmos' jumper pins on the motherboard. It's usually a 3-pin configuration with the jumper over the center pin and one of the side pins --standby position. With the power cord removed move the jumper to the center pin and the other side pin. Leave it for a few seconds and then jumper it back to standby. Plug the A/C cord back in and start it up.

After all those R&R's with the battery, is its holder still gripping the battery tight? Does the battery show 3 volts?

Try booting in Safe Mode. If it will run there then it might be a bad, corrupted, or Beta driver for the video card. If it runs in safe mode then download the newest non beta driver for your card (from AMD Radeon).
After resetting CMOS have you gone into BIOS set up? Have you reset the basic stuff including primary graphics? Does it continue running in BIOS set up without crashing?

You have to be a little bit crazy to keep you from going insane.

Thanks for replying ,i disabled the auto restart but even so does not show the blue screen,just straight up restart.
I checked the voltages and they are all normal,I tested my old 9500 gt in the system and it worked fine,no problems,the problem right now is that I can't make my PC start with the 660 even after resetting the CMOS,so I cant test the temps.
Even don't working I let the 660 running for some minutes and it was very cool,if makes any sense testing the temp if its not even working.

Thanks for replying, does not reboot with onboard but don't reboot even with the 660 plugged in,it only reboot if it detects the 660 .
Yes,they are clean and the fans spin fine.
The thing is that only removing the battery was working for me,doing the short was resetting but not detecting the 660,but right now not even resetting the CMOS is detecting the 660.
Yes,the battery is fine :) .

Thanks for replying,turning in safe mode don't stop the crash.
Yes I set up the bios to make the 660 as primary.
Now that you say ,I don't remember if it crash in the bios setup,but I can't test that right now ,because the PC its not detecting the 660 even after resetting the CMOS

Try cleaning copper contacts on GTX660 card with a soft clean pencil eraser, remove dust, then popping it in and out 4 or 5 times to burnish the contacts inside the socket.
If all else fails you can try a BIOS upgrade (Flash), sometimes this will improve compatibility, especially if the graphics card series is newer than the motherboard/BIOS version. I had this problem with a GTX750Ti on a Z97X-UD3H, I knew already that I had to update the BIOS for full support of my i5-4690K (K-Series support) but did not realize that it also needed the BIOS for the newer (at the time) GPU as well. Of course there is always a danger in flashing BIOS, especially if it is interrupted so reasonable precautions are recommended. I have always made sure it is plugged into a UPS (battery back up) and have not had any problems.

In # 4 you said it works fine with a 9500gt video card. That would seem to isolate the problem to your 660 card.

I am not sure why a graphics card would function fine for 2 minutes and then create problems UNLESS it is overheating.

One other possibility could be related to the memory. In which case you could run a memory test utility like memtest86.

Tried cleaning the copper contacts but to no avail,updated the BIOS, again to no avail,but thanks anyway,maybe i will try baking it. : )

If you are running on the on-board GPU, can you uninstall the 660 driver? Then try again with the 660 detected.

If that doesn't solve the problem? You have another GPU card?
Could be a hardware problem with the 660 GPU.

If the system runs with onboard and 9500 graphics and BIOS update and driver change does not improve things then we must assume that the 660 card is bad. If it was recently purchased the return it for a new one or refund. If it is yours and not new then nothing you can do will make things worse. I do not know much about 'baking' the card but assume that it is intended to refresh the solder joints so any plastic parts like the fan might be in danger of damage so look into Googling for details first. If the purchase was through ebay or somewhere like it, try a resolution through them for a defective item. If you have the opportunity you may want to also try the card on another machine to be sure.
A newer graphics card may be the ultimate answer in the end.

i used the 660 3 years already : ),i will take the 660 to a guy who knows how to fix the hardware(better than the risk of baking),hope the price is good ,otherwise i will save money for a 970,overclocking the 6300,but them i need a new motherboard and a water cooler for the CPU,that is so much money in my country : ( ,probably buying just used items .
thanks for the help anyway,helped me narrow the problem : ) .

thanks for replying ,i uninstalled the drivers,when i tried to install again, in the middle of the installation the computer restarts only with the on-board,but right now no matter what i do the pc don't detect the 660,my old 9500gt works fine in the computer,must probably be a hardware problem with the 660,i will take to a guy who will see whats the hardware problem,thanks anyway.

Did you try monitoring the GPU temps? CPUID/HWMonitor should do that.
