Quick stats: Nvidia 6800 PCI-E 256MB (vanilla), P4 820D 2.8GHz 1GB. Yes, it's a Dell. <img src="/images/smilies/biggrin.gif" border="0" alt="" title="Big Grin" class="inlineimg" /><br />
<br />
Situation: Got the comp in late 05, ran the video card stock for a while at 325/600, but soon OC'd to 420/880 with no problems. Ran lots of graphic intensive games like FEAR, Far Cry, NFS:MW, Civ IV, HOMM V, COD2 etc. with high graphics at good framerates for many months. Temps were good, no artifacts, no crashes. Also benched on 3DMark05 and 06 without any problems.<br />
<br />
Fast forward to a month ago: played SiN Episodes and HL2 Episode 1 to completion with basically max graphics and solid framerates. A week later I tried playing the poker game Stacked cause it looked fun (relevant here because it's in 3d), played for about an hour and got artifacts followed a second later by a game freeze. What the hell? This game is nothing compared to the FPSs I was playing earlier!<br />
<br />
I tried loading up another game right after the crash as a sanity check (C&C Generals to be exact) and I got D3D errors?! <img src="/images/smilies/eek.gif" border="0" alt="" title="EEK!" class="inlineimg" /> Looked online and people said a reboot fixed the problem, so I rebooted and everything was OK. The game was eh to begin with so the crash prompted me to get rid of it <img src="/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" />. Loaded up C&C again to make sure the card was OK (it was). Then I played old games for a couple weeks (one of them was Shadow of Destiny, PS2 port, 3d but not demanding, actually a really cool game <img src="/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" />), and everything was fine.<br />
<br />
Today, I tried booting up NASCAR Racing 2003, turned everything to max before launching, and 2 seconds after the car select screen came up got artifacts followed immediately by a hard lock. I reboot and the Windows startup screen has corruption. Uh oh. Doesn't even make it to the logon screen. Random corruption after the XP loading screen and then the monitor signal goes dead and the comp hangs.<br />
<br />
Tried a power cycles, same problem. Card itself is still on and looks fine but that doesn't mean much. Right now I'm in safemode trying to figure out if the card is dead, and if so, what the hell happened. Was it the poker game or the racing game (both of which were graphically inferior to the collection of games I've played on this comp before)? Was it a culmination of stresses due to the OC? Was it a random act of vengeance from the video card gods for my unusually high clock rate? <img src="/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" /><br />
<br />
Anyways, I'd appreciate help from all you OC experts. Any ideas about what went wrong here? Can I recover from this situation or am I going card shopping? <img src="/images/smilies/biggrin.gif" border="0" alt="" title="Big Grin" class="inlineimg" />

A similar thing happened to my 7800gtx. I was playing SWAT 4 when it crashed. Then I rebooted and my bios, windows, and games all were covered with orange artifacts. My card is broken now.<img src="/images/smilies/frown.gif" border="0" alt="" title="Frown" class="inlineimg" /> I got it in late 05 too and I overclocked it until sometime in March this year. Then I went back to stock because I didnt notice that much of a difference. Overclocking reduces the life of computer components significantly. Maybe your card just died of old age <img src="/images/smilies/rolleyes.gif" border="0" alt="" title="Roll Eyes (Sarcastic)" class="inlineimg" /> . I hope you dont have the same bad luck as I did. Good luck <img src="/images/smilies/biggrin.gif" border="0" alt="" title="Big Grin" class="inlineimg" /> .

I'd bet it was a combination of shoddy Dell PSU paired with the overclock that caused EOL. I've run most of my cards with insane overclocks right near the max for their entire lives. Not one has died yet...not even Ultra-powered ones! <img src="/images/smilies/eek.gif" border="0" alt="" title="EEK!" class="inlineimg" /><br />
<br />
So yes...Dell PSU, and bad luck. Does your card have multiple DVI/VGA ports on it that you can try? Have you held whatever key(ctrl?) to reset the overclock when booting?

</div>Hmm interesting, can you elaborate on this? What are the limitations of the Dell PSU? How does it affect the OC? Is there any way I can upgrade it if it's holding me back, or should I just not bother with OC'ing my next card?<br />
<br />
Speaking of power, there was a power outage a couple weeks back while the computer was on... would a surge have anything to do with the video card dying?<div style="margin:20px; margin-top:5px; ">

</div>I'm at work right now so I'll try both of those when I get home and report back the results!

OK there is a DVI and an S-Video out on the back of the card, but my monitor doesn't support those. Anyway I'm not sure if they'd make a difference.<br />
<br />
I tried the CTRL trick but that didn't do anything either. However, I got a friend to bring his 6800 over and after we plugged that in everything was working fine. Looks like the video card did bite the dust. No more OC'ing for me! <img src="/images/smilies/frown.gif" border="0" alt="" title="Frown" class="inlineimg" />

I have heard that Dell uses generic power supplies, although I personally have no knowledge of what they stick in their boxes.<br />
<br />
It's in a large system builder's best interest to use power supplies that support everything currently in the system, but not much else. Pushing a PSU to the limits causes it to die faster, yet still slow enough that it outlasts the warranty period. <img src="/images/smilies/thumb.gif" border="0" alt="" title="Thumb" class="inlineimg" /> <br />
<br />
Having a PSU fail to block a surge partially or entirely is also great, since then the owner has to buy all new parts! <img src="/images/smilies/biggrin.gif" border="0" alt="" title="Big Grin" class="inlineimg" /><br />
<br />
I have a habit of playing games right through thunderstorms here. I play right through those nasty light flickers and block-wide outages. The RCMP are right beside my house, and they rarely go out, so my power rarely goes out; there's just lots of tiny surges that my old powerbar and PSU have to handle.

</div>I was recently given a horrible assignment in school that involved researching and building 3 computers (horrible because when I build the "gaming" rig I noticed how obsolete my current on is). One had to come from a vendor and I chose dell. I went to the dell direct store and found out that their replacement PSU's are made by none other than PC Power and Cooling! Now, im not sure if the PSU you get out the box is a PC Power and Cooling, but if you ever need a replacement, thats where it will come from. <br />

*This information was given to me by a Sales Associate, while I would like to say that I know for a fact its true, I dont. He could have just been BS'ing me to get me out of the store.
