Ok now i have a major problem with my pc. When playing graphically hungry games (like cod5, bioshock...) the video card overheats (an educated guess) and the hardware starts making a beep sound (meaning the sound comes from the case, not the speakers.). I have downloaded speedfan to see the temperature values my pc goes through, and got these results: Right now : Sys : 28C CPU:33C AUX: 35C Local: 28C Remote 40-45)C (changing in between) HD0:29C Core:31C While gaming, the rest are same, remote becomes 52-53 when the beeeeping starts. (it's one long beep) I use ATI, so i have catalyst control center too; it says my current temperature (while doing absolutely nothing graphically speaking) is 80C tho. Why are these two inconsistent? If and when i play too long with the beeping sound coming, the computer shuts down without a warning (like an electric failure) and there is a blinking light (which should mean it's in like a sleep mode) and if i don't shut it manually (pressing the power button for a long time or pulling the plug), i can't open the computer. Today this changed for a reason i don't know, the computer doesn't just shut down in a split second but it closes all my programs and shuts down (like it would do if i did a manual command of "start - shut down") Don't start telling me to buy a new fan, i already want to do that but the computer is fairly new and it's guarantee will be cancelled if i dislocate any of it's members. i use the case open though, as it is stated not to be a cancelling reason. Lastly, I use my ventilator (yeah the big ones used to ventilate rooms) to cool the pc too, it is faced forward my video card (from like 1.5 feet away) and when it is used in like highest speed, it succeeds to maintain the temperature of the video card low enough for me to play any given game for a good 10 minutes. Then the beeping... (Necessity is the mother of invention anyway...) Ok, any methods to cool my video card down or the info if the card is starting to beep too early (that is if you think it starts beeping at too low temperatures to be dangerous to the hardware) and how to fix that would be appreciated. Emre.
