Strange ANNOYING problem.

when testing any component make sure everything is running at stock values. do not change voltage, cpu clocks etc... it sound like you have been changing values and why you may have unstable system

does your bios give you any error messages, or any beeps from motherboard when loading bios?

How does it sound like i was changing values? you must have read something wrong lol,I've not changed any BIOS settings and even if i did it wouldnt matter since i cleared the CMOS around 5 times and took the battery out etc and it still wouldnt detect my graphics card with 100% stock settings, there were no beeps no BIOS error messages and if i plugged the VGA cable into the iGPU port it would show that the system was actualy loading into windows just fine,the only problem is the graphics card not being detected. If anything its the stock settings that have caused the issue to begin with since it was setting my RAM command rate to 1T instead of 2T. I've been tinkering with computers long enough to know to set everything to default settings when things go wrong.

Could it be that the boards x16 slot is not providing enough power to power the 9800, but enough for the ATI cards? You said that everythings fine in the x8 slot. (I'm not blaming the psu here)

"Theres something weird about the whole situation,when i plug the card into the grey/white PCIe slot the motherboard will detect it but that slot works at x8 speed and id rather use it at x16 speed,but anyways,i did try using the card in the other slot and it worked for a few days like that but i noticed it was a little bit choppier in my games"

I bought a OCZ ZS series 650watt power supply from overclockers for around £75 that supplys 46 amps on the 12v rail and it didnt fix the situation. Thats more than enough for a 9800GT,and everything isnt fine in the 8x slot,it crashes after a minute of gaming. im now hoping it was a RAM issue caused by my motherboard incorrectly setting the command rate to 1 instead of 2. Also,a ATI 4850 uses more power than a 9800GT and that worked fine on the motherboard so there goes that theory.

I wish i could but i dont think they'd do that? If they test the card and say its working then why would they refund/replace my card? Im going to have to somehow prove to OCuk that its not working on my system and that means sending them the motherboard/ram/cpu back so they can plug the 9800GT into the machine and see for themselves that its not even detected by the motherboard. I was really really hoping the card wouldnt work when they got it because it would be a simple refund/replacement but it looks like its turning into a nightmare worst case scenario. the strange thing is i had this niggling feeling in the back of my mind a sort of bad feeling that the card was going to work when they got it and that i would have to send it all back in the end and thats exactly what has happened it seems.

I have asked them what tests they ran on the card and showed them the graphics card memory test tool the guy above suggested that i use to check the cards VRAM. i also asked if they are 100% certain the card is working correctly but im pretty sure a place like OCuk would know what they are doing when it comes to testing for defective hardware?

Now i just wish id waited a little bit longer and bought a better GPU because im pretty sure my motherboard/CPU/ram is all working correctly because i've stress tested everything on my machine and its 100% solid so it HAS to be that GPU:mad:

If that's the case I think you've got to stand your ground and either ask for a different card or a refund.
 
Look what i found.......

http://vip.asus.com/forum/view.aspx...ard_id=1&model=P8Z68-V&page=1&SLanguage=en-us

I didnt remove the CPU from the motherboard,its the only component that i didnt take out because i didnt want to mess up the paste lol. They also say if you turn the PC on with the CPU removed from the motherboard it forces it back to the way it was when it left the factory so i will try that out :)

EDIT just called overclockers and paid the testing fee for the lovely 9800GT so it will be back here tomorrow and i'll try removing CPU,powering up,then taking every single thing thats plugged into my motherboard out and leave it sitting on the table for like half an hour with the battery removed,put it all back together and turn it on with my fingers crossed lol. Wish me luck :p

Im joking m8 lol,seriously!

Im sorry if i seemed in any way harsh or offending ,that was not my intention at all!,i just meant that the theory you had(wich was a good one btw) was probobly not the problem due to me having a brand new PSU and the other cards i tried required a lot of power too. I read over what i said and i dont see the problem with it apart from the fact i didnt say thanks for the reply because tbh i've been stressed out and raging that my PC doesnt work,im sure you understand it slipped my mind to say thanks to any of you guys because i was focused on getting it working lol,the whole things stressing me out:p

Anyways,thanks for the help i do appreciate it and i hope there no bad feelings,this forum is the only thing thats been keeping me sane through this ordeal!
 
The admin on the ASUS website is trying to tell me its the graphics card at fault. wtf........

heres his response.....

Hi MrC..

I think about all you can do is contact them and tell them that your other cards work.. but the 9800GT doesn't... Maybe they are a bit confused.... tested somebody elses card..."

WTFFFF?????

EDIT,i've been teling the admin that overclockers is one of the highest rated hardware retailers in the UK who are highly respected and i dont beleive for 1 minute that OCUK is at fault due to their excellent customer service,its liek he's trying to play the blame game or something i dunno arrrrghhhhh lol,i wanna punch something.

Got it back,tried everything that was suggested,still doesnt work even though overclockers tested the card and found it to be working,anyways i've now confirmed this is an issue with the motherboard.Have a look at these 2 threads on the official ASUS support forum.

motherboard RMA time,cant beleive i've wasted £23.50 on an RMA for a graphics card that works perfectly because of the behaviour of this motherboard,what a peice of junk tbh.

I will be contacting ASUS asking for my RMA money back + the postage.

heres a response from the admin on the ASUS forum

"Apparently the 9800GT works.. and you have tried it in all the PCI-E slots and Nada!.. so what is going on with that is very difficult to figure. PCI-E resources for the video card PCI-E slots are derived from the processor... so there might be some sort of a continuity issue between the processor and the lands in the CPU socket.. but still, the AMD cards will work.. nothing makes any sense here.. so there is more to the story that remains unrevealed. If you can't get anywhere, I think you need to consider returning the board.. the 9800GT should work without a problem"

Before you RMA your mobo. Do you have a spare hdd or space to create a partion big enough for windows. If so, do a fresh install, using your onboard graphics. Then connect the 9800 and see if it is detected.

I think its the motherboard/BIOS thats not detecting the card i dont think its really got anything to do with windows but im willing to give it a try just incase im wrong.

How do i go about splitting my hard disk into 2 partitions? Im using a 500GB one and it has plenty of space left on it and running Windows 7 x64.

If i split it into 2 partitions can i put it back to one after im fiinished testing it?

Insert windows disc and partion before install
