Solve : Video card problem? |
|
Answer» hello, Get a new video card. Statistically insignificant. if a hamster chose Carrot A(organic) 8 times, and Carrot B 4 times in 12 tests, this is meaningless- Since the test is statistically insignificant. Most people would, assume that this means that the organic carrot is preferred by the hamster. It's not- in a statistically insignificant test, the results are determined more by chance them anything else. The way you determine whether an A/B test shows a statistically significant difference is: 1. Define N as "the number of trials." For the hamster carrot test this is 8+4 = 12. For your video card debacle, this is 2+0=2 2. Define D as "half the difference between the 'winner' and the 'loser'." For Hammy this is (8-4) ÷ 2 = 2. for the Video card "test" this is (2-0) ÷ 2=1 3. The test result is statistically significant if D2 is bigger than N. For Hammy, D2 is 4, which is not bigger than 12, so it is not significant. for the Video card "test" D2 is 2, which is not bigger then 2, it is not significant. human beings are notoriously bad at guessing these things from gut feel. For example, most people are more afraid of dying in a plane crash than a car crash, even though the latter is sixty times more likely. In your case, you had TWO cards. they both failed. out of a million, a test amount of 2 in an A/B test is statistically insignificant, and in fact, hilariously so. I could go on, but... meh. In an interestingly similar experience, I had three nvidia cards before this one I'm using now (a 9800GT). a 6200 FX would blue screen every time after installing drivers. a GF-2MX would blue screen every time after installing drivers. a 5500FX would blue screen every time after installing drivers. however, unlike your case, I took the logical approach- given that I had four different cards that all failed to work, it seemed obvious that at least one of them was fine. Therefore, since none of them worked, it was fair to say that the cause was in fact, something else in my PC. the problem ended up being with my motherboard. it's called, Finding the common problem. having a single card fail on a PC can be the cards fault. RMA-ing that card and getting another defective card back is highly unlikely, so the problem is probably something else, not the card or how "riddled with problems it is" Quote from: nitelife2989 on May 12, 2010, 09:17:43 PM i checked the Video card temp with Speed fan and its overheating from where the specs showed it should be. i turned off the PC for a couple hours and tested it while it was cool and i still have the problem. i believe the video card may have been over heating and is now junk. looks like you were unfortunate sometimes you can get lucky and have a card overheat and still not have permanent damage (I came for help on this forum before in a similar situation, when my 5500FX started having problems- underclocking fixed it, but the problem ended up being that the fan wasn't spinning). You could try underclocking the card by a few mhz with RivaTuner, and see if that helps, at least until you are able to replace it.how old is this graphics card??get a graphics controller software from the manufactures siteThe card is a year old. i will try under clocking but i still think its junk cause i cant get any game to work. my other PC has a 9800 GTX works great i might get another one for my 2nd PC If the problem still occurs and the card is at a decent temperature - It it probably damaged. Have you cleaned the fan/heatsink? Does the fan spin at a decent speed? |
