Hey guys, cheers for reading this thread and hopefully trying to help me.

Once upon a time I was a happy little boy who saved his pennies and bought a $600 MSI-6800GT :D (didn't realise 7800GT came out the week later but that's another story)

Awhile back i was trying to get some more frames in R6-Vegas so I clocked my AMD 3500+ from 2.1 to 2.4 GHz, No Worries... however no extra fps :(

So i decided to hit up my Nvidia Tuning (the one that comes default with drivers) and it over clocked it from stock up around about 50MHz.

Jumped back in the game, more FPS :D but i noticed black 'tearing' across the screen :(. Being scared immediately I jumped out and put clocks back to stock and never had a problem after (or so I thought).

Not long after my PSU started to make very odd sounds for no reason, I figured i'd hit my computer, it rocked and the PSU stopped making sounds. (only mentioned this cause I thought it might be relevant)

Anyway, all was good in the land of my computer until recently. My games either crashed saying 'Could not find Direct X 9 Renderer' or My monitor would just loose signal. Counter Strike: Source, Battle For Middle Earth 2, Vampire The Masquarade, CoD 4, MoH: Airborne... no longer work (what a bummer).

While doing some Hard Drive maintainance I noticed there were 2 folders inside my Nvidia driver folder, odd I thought, I must have 2 sets of drivers, silly me. I uninstalled them both and installed the latest (169.21).

Yup, no worries, installed fine, try to play CoD 4 (@ 1680x1050 btw, stupid 22" monitor) and what do you know it works fine! *2 Seconds Later* Oh, okay i'll go play Counter strike *Boots up, choose server* and my monitor becomes blank, flashes, and looks for a signal. No Luck There.

The more and more I try, it seems as if my 6800GT has lost the ability to render DX 9 (tried running CSS in DX 8.1 didn't work either).

So what am I asking for, well a solution, the actual problem so I know what's wrong, was it my fault because of the over clocking and i've technically still got 5 months of the 3 year warranty left would I be able to send it to MSI?

Once again, thanks for bothering to read about my problem

What are the temperatures ? Is your card very dusty ?
It MIGHT be the thing that happened ages ago , or maybe your card has simply crapped out .

Dusty, no. I do ocassionally open my case and clean it out. However on the fan it seems like it has been burnt, as the plastic has gone from clear to a brown-ish distorted colour, i'm not quite sure how to explain it.

Usually if you oc it you lose the warranty...

Am I correct in assuming that it only happens with 3d apps? It may be that you've hit some problem with 3d clocks. There are 3 settings on most GPUs, 1 for 2d apps, 1 for 3d apps, and 1 as a backup. It may be that when you oc'd the thing you killed something for the 3d setting.

Just a theory though. Also, I recently had a problem with STALKER Shadow of Chernobyl where I got the "no signal" message whenever I tried to run the game. Reinstalled and it worked fine, so it may just be CSS.

Nah, the signal being lost happens with pretty much everything EXCEPT Call Of Duty 4 ... (It makes no sense to me) - But everything is on bare minimum however. I'm thinking however CoD 4 is forcing SM 2.0. A picture i'll do a bit later. I'm not really that fussed I was just wondering if anyone had a clue what was going on, otherwise i'll just buy a 8600GT or a 3850 (in the meantime) till i can get my new computer.

Just for the record... the 6800 GT quite a bit faster than my X1600 Pro... so you can easily run CoD4 at medium settings .

256mb/128bit @ 1680x1050 ... on CoD 4? no way. Gotta run it low. Odd though I booted it up a few hours ago and it crashed, my desktop was forced to like 4-bit colour. and it said 'out of memory' and the whole Direct X 9 Renderer crap came up again :mad:

Oh sorry... forgot about the resolution .
I'm running it at as high as the game allows me to turn the settings(which is medium) and at 1280x1024 , I still get playable performance .
Well , I suppose your card is done for ... or maybe it's just a corrupt BIOS or something... not sure .
