Constant 3d lockups... cant run 3d test or games, i managed to get CS:source to work for and maybe an hour before it crashes, after i used ATi Tool to underclock it by 100MHz on the core and mem. clock. I have 4 case fans(tried several dif. layouts), but my temp. usually crashes at only 57-59C. Ive read many forums and most say its faulty drivers, or overheating. Ive also tried a few dif. drivers. Nothing seems to make it stable... PLSSSS HELP

Re: xfx 8800gt 512MB
These can get warm/Hot under constant use.
If it,s new i,d suggest you may have a faulty card.
I,m not sure whether you can actually remove the fan from the GPU Chip, but if you can.
I,d reseal with a quality thermal compound such as arctic-silver or similar. Theres a possibility that the card has overheated and damaged the thermal-seal between gpu and heatsink.
The other option, is to direct a fan blowing cool air towards the card, rather than trying to extract air from it.
If it,s new it,s faulty ( get it replaced )
If i can be of any further assistance/help.

This sounds like either a case of graphical artifacting, or your pc is simply crashing.
Graphical artifacts are things not normally seen on your monitor created by overuse of the graphics card, such things as white pigments and the odd pixel patterns you saw are some signs of this. I've experienced this problem, and have had the speakers make the noise you heard noise upon restarting the pc. To see if this is the cause I would try running an extremely graphically intensive game or program such as a 3D benchmark to test the limits of the graphics card, and if you see the odd pixelation during the testing, then it is most likely that the card is the problem, and you should call its manufacturer for a replacement.
If your pc is simply crashing then either your power supply is not putting out enough power for you graphics card, or the graphics card is not hooked up to the motherboard properly. The first to do to check if this is the case is to run your pc until it crashes and see how hot your pc has gotten, if it is very hot, then your power supply could be overloaded, or you may not have enough airflow in the case. I would suggest opening your pc and looking for anything out of place, and even perhaps getting professional help from a technology store.
Thats odd. Try cleaing out the cooling fins with compressed air to get ou the dust. Take out the card and put it back in. Have you tried updating the driver? try this stuff and see if it helps. I hope it does. cobrasdh
your card is probably overheating. the alphadog editon has an extremly small cooling for the gpu. try cleaning it with a caned air spray and check the NVIDIA control panel to see the temp. of the GPU if the problem is solved try running a game benchmark to see if that works.
Sorry for the bad news, but you've seem to have witnessed a graphic card meltdown...
During games, cards get quite melting hot! If there's a little problem or inefficiency in the card cooling system (Active Fan or Passive Airflow) Your card will simply melt a few little contacts, enough to produce what you saw or even worse!. (Basically just in the graphic 3D render portion of the board, thats why you could still see windows some times but Aero (3D) started glitching later).
If you wish, you can verify this at your own risk opening up your case and placing your finger on the free corner of your card and bending/arching it a little to the sides when windows or your games are running... It may restore contact at the melted away points for a few seconds for you to see, but won't repair it, you'll maybe see how images get better or worse with the bending, proving the meltdown situation.
Return your card if you can or buy a new one, before the crashes mess up your windows. Buy a new one from a good manufacturer and clad with an elaborated cooling system, if you plan to run 3D heavy games, stay away from the weird branded, cheapest or heavily discounted cards are usually the ones most prone to fail this way. If you go ATI, buy ATI made cards. If you go NVidia, buy BFG for example.
First try to pop the 8800gt into a friend's computer, if it works for them uninstall and re-install drivers yet again, followed by a format if appropriate. If it does not work, try to get a RMA on the card.
It is a known issue. It is not a fault with the card, but a power saving method used by Nvidia. If the card is not being stressed, or even if it is, it will clock down to it's 2d speeds. This is fine if you are just surfing the web or other light tasks, but can cause chaos if you are gaming or folding at home.
You can force your card to run at it's maximum clocks in 3d mode by using a program called Riva Tuner. There are several good posts on the net on how to use this fix, but I can't seem to link to them as this site will not allow me??
I am using it myself, as I had the same issue with my 2 GTX 260's.
