first, try going to direct into the wall for power. If it stops, its UPS, if it doesnt, youve elimanated that much. If that doesnt do it, try to isolate the noise. Caps are flat one the top, and straight on their sides, look for bulges in them, it could be mobo,psu or your card
1) A loose / disconnected connection. Reseat / reconnect
2) Insufficient power from your PSU. Try a different PSU or test with a PSU checker to make sure your Voltages are right.
3) Clear plastic coating from your video card is peeling off and making contact with a fan or exhaust vent. Remove and visually inspect your card.
4) Your vid card is not seated properly in its PCI slot. You should reseat.
5) Something on the video card has gone out. Remove the card and visually inspect for burn marks, funny smells, debri, abnormal looking caps (usually round and smooth), blown resistors.
6) Card could be overheating. Check the fan on the card to make sure it is spinning normally and that the case is providing good airflow. Double check temps with RivaTuner or whatever you like best. Personally I don't trust NTune.
I have had all of these happen to me during normal operation of several different machines all using video cards from both ATI and Nvidia.
Is this a very loud noise or low to moderate? The fan on the video card would ramp up rpms when playing a game like crysis so this could be the source of the noise. That may be a normal problem everyone is experiencing but to me a noisy fan is a fan that has a shorter life so I would either get an aftermarket cooling setup or RMA it.
Like jaydeejohn said, disconnect the ups first and go directly into the wall to eliminate that question. I use a ups too and dont have this issue but its a different setup too.
That "loosish" capacitor concerns me. You mean it wiggles loosely on the motherboard? I wouldnt move it anymore if thats the case, it would only get worse.
Just to add something else into the pile of suggestions.
If you're not 100% certain that the sound is coming from the GPU, Are you by any chance using a CRT monitor at all?
CRT Monitors when they get old can have a fit when they go into certain resolutions or refresh rate (usually whatever it has been used in for the longest) and will make a high pitched squealing sound that is hard to pin point the exact location of.
Try changing the refresh rate or resolution on your monitor (only if your using a CRT) and see if the noise stops.
yes it sounds like a old capacitor and ati use solid-state capacitor's on there cards
so that leads me to believe its ur PSU they still use the old one's
probably a bad capacitor in the corsair PSU, but if it is ur card i would RMA it
the only way i know of is to try the card in a friends PC and play crysis, see if it makes the noise, plus i think the caps on ur motherboard are solid-state as well so i dont think it could be coming from there
or maybe get a loan of a PSU and test it with that
Ok, so my GPU makes noise and when ever the crysis level starts the computer crashes and a red screen that has white text (looks like blue screen of death) and says something about a memory dump then restarts the computer.
This is really a turn off, i really wish this get fixed. Any suggestions?
