Graphical Glitches / Motherboard Problem?

[Udders]

Hi everyone,

iv been having problems with my graphics card, im running a 6600GT and an asus P4P800D motherboard, everything on my PC is running at it's normal clock speed and the AGP slot is running at x8

How ever sometimes when i boot up it says my 6600gt isn't getting enough power... i have the molex on the card pluged in and i have just brought a new thermaltake 500W power supply.

In games i soem times get missing texture and some textures are streched from their location 1/2 accross the screen so somewhere else... it also sometimes crashes and says "your 6600GT is responseable for system instability" but it's brand new and i had near enough the same problem with a ATI 9600pro (untill the fan burt out (HAHA))

at first i thought it might be the chipset on the motherboard conflicting with the card but now i think it might be the AGP slot? is that possible? for the AGP slot to restrict power and run at lower performace?

any insight from anyone would be greatly appreciated!

Why do you think it’s the AGP slot? I doubt if it’s a problem with the Bus otherwise the system wouldn’t work.

There are a number of things you could try:

Make sure the card is securely fastened and all the contacts are clean and nothing is obstructing the connection in the socket.

Make sure the power connection is secure. Try using a separate molex connector on a different supply lead just in case it’s a bad connector or supply lead.

Check that all your voltages are stable by running motherboard monitor or check the power output using a multi-meter. If the power supply is poor and not within the recommended tolerences, then consider the PSU you bought to be faulty.

Make sure your are using all the latest signed drivers (chipset and display)and that your settings are ok.

If you can, put in a card that you know is working.. just to eliminate power/motherboard problems.

Failing all that, I would say it’s a duff card and would consider an RMA.

Iv had the system running with another PSU & Graphics card and i got the same problem...

reason i think it might be the AGP slot is because of the power issue. i know that even though it's running with another molex it still gets some power from the motherboard. and the fact that some of the graphics keep glitching... but that might be down to the chipset i really dont know... this has been around for sometime so there isn't a chance in hell of a RMA

But ill check to see if all the contacts are clean and ill update the chipset drivers when i get home later!
