7800GTX Direct X errors

[Enyo]

okay this is an odd problem that ive only recently noticed, my 7800 gtx seems to occasionaly have rather severe dx errors in certian repeatable situations eg loading a certian map in a game..

this first happend on FEAR with environmental textures sometimes going completly black (gun and arm and characters still textured) and extreme slowdown (0fps) this was orignaly fixed by rebooting it and happend rarely.. it now happens every time i run the map im currently on although i managed to get half way though the map with it working perfectly (then saved and left) i cannot now load this map in anyway. multiplayer works perfectly the other maps are fine but this one map has stopped working

COD2 never ran at all and gave "unrecoverable direct x error" (roughly) i could occasionaly get it working in safe mode at 640x480 but no other resolution in safe mode


edit: oh and 3dmark05 once gave d3derr_outofvideomemory on the demo (but went away when i reformated windows xp sp2)
CIV 4 also gives d3d errors on starting now too.. but it worked perfectly the first time i ran it

quake4 works perfectly.. b&w2 perfect.. lost coast perfect..

so far ive tried 4 differnt driver versions (using driver cleaner inbetween) reformated once and contacted vivendi tech support, who gave up and sent me a survey instead, after a few emails.

the system its running on is perfectly stable and all at stock temps are in the 30's-40's and the voltages are within 1% deviation from the rated voltages

its a

4000+ AMD sandeigo
1gb corsair value ram
410w hiper psu
3gb page file on 80gb hdd
directx 9.0c
7800gtx (gainward) running on 81.75 beta's atm

ive not heard of anyone else having a problem like this so im not sure if it is a hardware fault.. anyone got any idea's?

was that taken with a DMM or was that from some monitoring application/the BIOS?

its an asus probe on A8N-SLI DELUXE and in bios there both very similar readings

argh i need a solution for this before next sunday (lan party!)

First off, beta drivers are tagged beta for a reason. If you're having problems with your card, you should downgrade to a certified driver revision to troubleshoot. Temperature != stability, or perhaps more properly here, correlation doesn't imply causation. Cool temps don't necessarily mean the card will be stable at a specified o/c. Another possibility, is that the card is bad. There are few other things that it could be, except some major fubar in your system setup. The powersupply could be another possible problem, but you seem to think that is not the case. If downgrading and restoring the clocks (if it is even oced) doesn't fix the problem, return the card. There's not much you can do.

The out of memory errors seem especially suspect and indicative of a hardware problem.

fun fun fun,

may have found the source of the problem, i now have a fancy dead asus a8n sli deluxe, it hangs at the bios splash after giving post ok beep

Sounds to me like your Windows Installation became corrupted, but I suppose the motherboard could have been at fault....

On a separate note, I would feel very uncomfortable running such a power-hungry system on that 410W unit. I'm not saying that you have to go for the most expensive PSU out there, but I personally would not trust such expensive toys with an average PSU.
