HI
I have a problem with my 6770 all of a sudden reving up to 96% when i boot into windows 8 and i have to go to device manager and disable it then re'enable it to stop it. When i boot into windows 7 it doesn't do it. It never did it before in windows 8 either. Any clue how to stop this?
I have uninstalled the display drivers and tried other ones no go.
Only way i can stop it doing it is by disabling it like i said but this is a joke to have to do this after every boot of windows 8. Other than that the 6770 runs fine while gaming etc.
I'm at a loss with how to stop this annoying problem.
I did blow up a power supply a few weeks back but when i put a new one in the pc seems fine other than this problem that started after i put the new psu in. Any help will be appreciated or any ways i can find out which process or program is actually making the gpu go to 96% in windows 8 would be great thanks
UPDATE
btw thats a constant 96% like a game is running or something but there is no game running?
 

I tried all the latest ones 12.10 & 12.11 beta plus the windows 7 ones but xbmc had display issues with the windows 7 ones
My PSU is a 750 watt cit with 22 amps on the 12 v rails my old PSU was evo labs 700 watt with 20 amps on the 12 volt rail but that blew after a few days at 4.1 ghz on my 1100t so now scared to overclock again but thats another issue entirely lol.
for now I want this GPU to stay at 0% usage *(or thereabouts) till i play a game like it should
 
Ok lets start with the PSU,

The reason your old PSU blew was
20amps*12v=240watts. As it was not a good quality unit I wouldn't trust it to output its rated power. Not to mention 240 watts is not enough. I assume it had multiple rails.

If you pushed your cpu to 4.1ghz it means that it was going to use much more power. And if all of that is on one 20amp rail the psu will not be able to handle it.

Your new psu is not much better, you should get a good quality psu to start with. With that psu I would definitely NOT overclock your cpu.

You should consider getting a new psu. Even a 500watt good quality psu like a corsair would be more than enough.
 
Maybe it's broke but why would it do it in windows 8 and not in wiindows 7? I'm not expecting anyone to know more than me on this co's it's a bit of a strange issue which i expect I'm on my own with. Will just have to keep disabling it every time to slow it down to 0% usage then re.enable it again pain in the arse tho and wish you could get a process?task manger for GPU's so i could find out what graphics or program is actually causing the gpu to be used
 
As for the GPU drivers it may be a problem with the early drivers for windows 8. Try using driver sweeper and then reinstalling the latest drivers.
 

Yes i know the other ones not much better butr bought it for £20 just to get my pc running again but know it is no better well hardly. why do they put 700 watt psu if it's only 240 and how could 240 run my pc anyway?
I'm gonna get an OCz one soon as i get some spare cash
 

it had dual rails as does this one i bought for £20 as a makeshift replacement. I also gotta upgrade my motherboard but stuck with what i have for now
I've seen a few 620 watt ones from ocz and another firm that are meant to be lots better for £57 so just gotta wait till i can spare that money
 

got my eye on this one http://www.amazon.co.uk/OCZ-OCZ600MXSP-UK-ModXStream-Power-Supply/dp/B001GLFD54/ref=cm_cr_pr_sims_t#

What do you think? i just read the article you linked me F'ing robbing B's is all i gotta say lol Well i think this one would be ok and is about at the limit of my budget for a PSU at the moment

Oh btw i just checked specs on this and read reviews of people running two gtx 680's on this psu but still it only says 25 amps on the 12volt rails? my cit one says 22 amps on the 12 volt rails so how is this one much better than what i have although it clearly is.
What do i need to find to guarantee a 4.0+ ghz overclock not busting my psu? 30 amps on the 12 volt rails?
 
Well the psu chose apparently has enough pcie connectors for one graphics card but it will be much more than enough for a single hd6770. Now if you want to overclock your cpu to 4ghz you should be fine with that ocz 600watt, however you would be cutting it rather close. It is better if you go with something like 700watts, especially if you plan on upgrading your gpu in the future.
Use this calculator to calculate your power consumption:

Hope this helps!
 

even though it just says 25 amps on the 2 12 volt rails this one is 22 as i said but I guess it's just quality that counts. will that psu be good for 4.0 ghx + and maybe SLI if the need takes me (it says it is but as I learned from ur link they can be robbing B's who lie about their products capabilites)

I will buy that PSU in a few weeks then and stay at stock speeds till then.
Any ideas what could be causing my iniitial problem with the GPU? Can't be bad drivers surely as it never did it before. could it be hardware failiure ( doubt it when in W7 it's all good)
I may try install some older w8 display drivers if i can find them
 

yeah good point one power connector yet it says sli ready? btw I'm not gonna stick with a 6770 forever lol. I need something thats gonna do the sli if i need it and better gpu and be able to overclock my CPU will i need to spend more than £55 on a psu to get that

Found this one same'ish price same specs but more wattage not sure about make tho http://www.ebay.co.uk/itm/Powercool-GT-800W-SLI-Gaming-Power-Supply-800W-80-Plus-700-Watt-PC-Computer-PSU-/140772346341?pt=UK_Computing_PowerSupplies_EH&hash=item20c6af89e5

this one says 58 amps on one rail for £63
http://www.ebay.co.uk/itm/XIGMATEK-700W-SLI-Gaming-PC-Power-Supply-Unit-PSU-600-Watt-/261101124601?pt=UK_Computing_PowerSupplies_EH&hash=item3ccad6fbf9

is the one above, the powercool one ok? more in my budget as unemployed due to illness which sucks
 
Stay off ebay when buying power supplies. You should avoid that psu that you posted. Yes you will have to spend more money, but it will be worth it in the long run, as a good PSU will not explode, destroy your components, suck unnecessary power, or risk burning down something. I will also allow for future upgrades, as you mentioned that you might want to upgrade in the future. When buying a psu look at brands such as: corsair, seasonic, antec.

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139021

That psu costs $89 after a rebate in the US, however you are in the UK right?

So this is the same PSU in the UK:

http://www.amazon.co.uk/Corsair-CMPSU-750TXV2UK-Enthusiast-Series-Performance/dp/B004O0P9VC/ref=sr_1_3?ie=UTF8&qid=1351624512&sr=8-3
It costs 83 pounds.
 

Since when is $89 amount to £83 lol
yeah i will have to save up for a couple weeks just got so many parts i wanna get SSD new mobo with better chipset. Begrudge having to buy another PSU but I was scared when i blew that PSU co's built this rig myself. £83 isn't undoable for me but I will have to give my mate the money in 2 halves (he does all my online shopping for me. I just give him the cash)
But will that one be good for overclock and 6900's in sli (7900's use less power i heard) when & if needed? if yes than I guess it's worth the money

btw i just had a good read and that looks like an excellent psu for a little more money :) it says 60 amps on one rail which i guess is good lol better than 22 amps on 2 rails? who knows but i guess it comes down to quality again.
Thanks for your help and if you get any ideas about my other issue let us know. thanks again you have been great and i will save for that PSU right away
 


I have the same exact PSU, and up until a few months ago, I ran crossfire HD 6770s. Now I have an HD 7870, but I still keep those cards as backup.
 

yeah i knew that sli was invidia. but just said two 6900's as a guide i doubt i ever will do a crossfire setup anyway but would like to have the juice there if I needed or wanted it. Chances of me being able to afford 2 high end gpu's is pretty slim till i get well and back working at least. AS long as it will run one card now and in futre then i guess that would do. I can't see me going crossfired anyway tbh
 
In response to novolux:
For crossfire hd6770's it is much more than enough, but hd6970's in crossfire are a different story.

Although they should be able to run, as from what I read they will draw 600watts under load. But if you want to overclock them, and the cpu you may need more juice.
 

ok thanks for that info mate. any idea why my 6770 is getting 96% usage when i boot windows 8?
 

OK mate well I'll keep all this here for when i get some cash to order it so i know what to get. appreciate your time and as i said try figure out what's causing that strange issue with the 6770 reving up and getting stuck at 96%
btw is this gonna damage my gpu if i just leave it at 96% and just let it do it's thing? I usually disable it then it goes back to 0% but would prefer to just put up with fan noise and leave it as long as it won't break when i play a game or something. What would you do? unfortuanately buying a new or better gpu right now isn't possible
 
Well, I would try to remove the drivers with driver sweeper and reinstall them, it is likely a bug in the drivers or windows 8. You could also try flashing the BIOS of your graphic card for a newer one if it is available. Also what temperatures is your graphic card reaching?
 

well when i first noticed it it was in msi afterburner and it reached 105 degrees but since then when it's done it it hasn't gone over 80. Wierd right? when it hit 105 i shut it straight down via device manager. Earlier i had my case open to reroute some cables and when i rebooted windows 8 it didn't do it. But sure it will do it again. But I will keep my fingers crossed
105 degrees is very high, pretty sure i read it right but i reach 80+ degrees gaming even with the awesome airflow i get with my Zalman z11 case (cpu never went over 40 degrees even @ 4.1 ghz while prime testing) max cpu temp i get is 36 degrees during gaming
 
105C is pretty hot. Not too great for a card, its best to keep it under 80, at least thats my preference. Set up a custom fan profile in afterburner to keep it cooler while you troubleshoot. Also did you try cleaning out the drivers and starting again?
