Major hardware issues...help direly needed.
note: this is rather long but i am at a complete loss of what to do, please read through and give me suggestions! thank you.
I'm on my 4th motherboard because of this darn problem so any input is going to be greatly appreciated..i originally purchased an asus a8n sli deluxe motherboard, an evga 6800gs, an amd 64 3200+, and an antec truepower II 430 watt psu, and a WD 80gig harddrive, and i'm using two cd drives i took from my old dell.. The problem with the 3 asus boards i went through was that i would install the OS and then get to the point where i'd go to install the graphics drivers and other necessary drivers and after i would install the graphics drivers i would do the normal restart and all of the sudden my monitor would lose signal, the cd drives would not open, and nothing was working...the fans and fan lights and everything would come on and the harddrive activity light would be frozen in that being accessed constant light but i couldn't do anything. The first time i installed the new stuff i didn't even get the OS on before it did this, but the second two times it occurred right after i installed the graphics drivers...So, getting fed up thinking it was just asus i went and bought an MSI k8n-neo4 platnium motherboard and installed it and all the updates and drivers etc and it worked GREAT, every game ran smooth and butter and beautiful and i was at the windows login screen in under 20 seconds on start up...but 20 days exactly after everything had been installed the SAME exact thing happened, signal loss to monitor and drives not opening and all that horrible stuff. Now i am at the point to where i do not know what it is...i called msi and their guess was it was the graphics card...or maybe the PSU. so my idea was to send in ALL my parts saying they were all faulty and hopefully fix it all in one go. But, after i put in my old parts i had corecenter up and it was kicking up an alarm saying my psu was putting in too many volts, i was about .3 volts too high in two areas...could this be the cause of all my problems? would that .3 volts cause this? and could it possibly happen at different times depending on the motherboard??? any help and suggestions would be GREATLY appreciated..
sorry for the length..thank you to those who read it all the way through.
