GPU problem????

[Nickolp1974]

couple of days ago my psu went bang, got a new one yesterday and everything works ok, but just been running a few bench's and scores are well down 20-30% lower with same clocks that i have done in valley/FS ex.

Have removed drivers and afterburner and reinstalled with later versions and the results are the same.

GPU usage is at 99% so no problem there

motherboard possibly????

what do you think any ideas where i should be looking??

just ran firestrike same clocks as i used in the thread and got a gfx score of 7872, before i got 10006, wtf going on???

think my original bench's were on the beta 4, tried beta 6&7 still the same. Its a massive drop whatever way you look at it, will give it a go though gregster. i'm wondering if the bang has corrupted the vga bios or something

just tried ln2 bios and no change, just going for dinner, will try the 12.11's when i get back

When i installed driver, i got an error, but i nearly always get this for some reason.

now sorted and i think it was related to windows defender.

Cool that you found it

Thx for your help G, i'm hoping it was that, also had to reinstall system info for futuremark, seems when psu blew its corrupted a few things, i may do a clean install of windows to be sure.

Are you on win8 if so what virus prog you using?

I only just did an install when i got my rive, so about 3 weeks ago! Tempted to get another ssd and have 2 boot drives, one for everyday use and other with a streamlined windows just for benching.
