I went out and bought a Sapphire HD 4650 1GB DDR2 AGP last week, Installed it into my machine which was running XP Pro 64 Bit at the time and it was running fine. A few days ago i decided to clean install Windows 7 Home Premium 32 Bit and thats when the problems started. First of all i could not even install Windows 7 with the graphics card in my machine because it would crash on me during the installation, so i took it out and used my onboard graphics and installed it that way no problem. Put the card back in, installed the latest drivers for the card without a problem and it seemed to be fine...for about 20 minutes, It'll crash whatever i seem to do on my computer. Surfing, listening to music, windows live messenger and gaming, their is no pattern apart from when playing games.
Whenever i try to play a game it'll crash without a doubt however, depending on the game determines the time of how long until it crashes. Dead island as an example, will crash whenever it gets to the intro video before the menu, Dawn of war II will get to the menu fine but as soon as it is in gameplay it crashes. True crime streets of L.A & Dawn of war (original) will run fine without hiccups for 1-2 hours then all of a sudden will crash, forcing a reboot. Sometimes it BSOD's, other times it'll crash and restart it self or i'll have to force shutdown. Having another HDD, i installed XP Pro 64 Bit on that and ran the exact same games without trouble, no crashes, nothing, zilch.
For the moment i've had to put my old 7300GT back in my system to run windows 7, which it does without problems. I have tried to install four different drivers for my HD 4650, Cd drivers, the 10.1, 11.1 and 11.8 (latest) hotfixes but all seem to be affected by the same problem. Just wondering if anyone could try and help me out with this, i really want to use my card on windows 7 and it's so irritating that i can't.
Note: All the temps in the computer are all fine, the cpu and gpu barely hit over 50C full load.
your problem is the TDP of the components the mobo was designed to support until 89watts and ur athlon is for 125 watts u have a serious problems of energy the mobo will be corrupt and not work properly, in others words if u still that configuration (cpu of course): k9mm-v r.i.p.
i have the same motherboard and i recomend the athlon 64 x2 6000+ core windsor with 89TDP
pd. sorry for my english, i from perú!
