Hi this is my first ever post to a forum so apologies if its not up to scratch

I recently purchased a Gigabyte G1 980 ti for my rig, it appears to run fine other than a great deal of coil whine, it'll run old Dx9 games perfectly as well. However in newer games such as call of duty or Vermintide along with others it'll stutter, crash to desktop after about a minute with no errors or give me a black screen that apps seem to run behind but can no longer be accessed and forces me to hard reset.

Before crashes it runs silky smooth in the way exact way the card should perform, i think the culprit may be the PSU as my rig was originally a custom build by cyberpower I have still got the 4 years old 950w PSU, is it possible that this has degraded enough to force crashes during intensive gaming?

As well as this setting my monitor to 144hz seems to make the problem worse.

cheers for any help you can provide :)

Not posted on here for a while but had time to test my machine properly with battlefront, fallout rainbow six etc. It turns out the problem was CPU related, for whatever reason the new GPU didn't like the over-clock on my CPU and was causing games to crash, I dropped the clock to 3.9 and its solved all problems even the GPU coil whine has decreased. I'm unsure of the relation between a new GPU and a CPU over-clock but it might be worth trying if anyone else finds themselves in the same situation.

Cheers guys :)

Prebuilt PCs don't tend to use great power supplies and after 4 years I think it is safe to say you should invest in a new PSU. If your PC is crashing, go to the event log and check what the cause of the crash was.
But I'd definitely recommend getting a new PSU

no win 10 is great gurus yet ??

I just googled ''NVidia driver windows 10 issues'' lots to read on it ??

maybe one that's solved can help ?

http://www.tomshardware.com/forum/all.html?refine=nvidia+windows+10+crash

10 is new and theres some bugs to be worked out personly I would never use it just reading whats said and reported


thing is with out a backup psu or parts to check its still all guess work ?? but for a 980ti and you report ''great deal of coil whine '' ?? that's something you don't see with hardly at all except for the 970 card it was common with ??

tough call test the card in another computer that will handle the card and a known good psu ? try another driver just because its a newer driver don't mean its a better driver -

check display settings use the monitors native resolution as a base set that in windows display settings [control panel-personalization -display ] and then in the NVidia control panel all should be set the same

with older games todays high res and refresh may not be supported some games I have to run a 1024x768@60hz cause it don't support 1920x1024 so you have to make them adjustments in the game and monitor [wide -dot to dot- normal -ect....] little things like that so check the games specs

that coil whine is something you don't here about much at all outside of a 970 in the 900 series ?? odd.....

not to add more bad news but like at newegg the giga 980ti g1 is the lowest rated card at 49% ??? hard to overlook that


with the newer games maybe just a issue

Ive heard of a lot of problems when going from an amd card to NVidia without properly uninstalling old drivers. But since both cards are NVidia I don't know if that would be the problem. Couldn't hurt to do a fresh install of the drivers though. Id recommend DDU for quick and easy uninstall http://www.majorgeeks.com/files/details/display_driver_uninstaller.html

for me with the same cards like NVidia brand its all ways best to do a fresh driver install and not just swap out the cards.

the driver installer scan your hardware and unloads the driver packets for that card so say the 980 card may need something that the 770 did not need or a file required for the 980 was not needed for the 770

a card of a different series 980 970 770 what ever may have feature sets on one the other may not

weather all that's true or not I just do a fresh uninstall and install of every driver better safe then sorry and fighting a issue if that may be the cause in the end ?? [opinion]

I also look over each drivers foot notes to see if any changes or known issues between them that may also affect weather I want to use it or not

like I said just because its a new driver don't make it a better driver
