Hello. Here is the story. I purchased a new PSU, motherboard, case, and some other accessories for my computer recently. I pulled everything out of the old case, and built everything in the new case. My old motherboard was an Asus Crosshair. I purchased an Asus M3N-HT Deluxe, which I promptly installed. After about 14 hours of working properly (left it on overnight, but NOT in windows... windows would not boot it bluescreened complaining about the disk), i shut it down the next morning. it never passed post again :(
no beeps no nothing fans spin up thats it.... no beeps even with no memory... asus says its fried for sure
take it back and get a new one
new one lasts about 80 seconds and dies right in front of me... bluescreened on windows boot and then froze later on in the bios, after which it would not come back....
psu, right? i went and bought a psu tester (thermaltake dr. power.... i know, it was the only one they had). i have never used one before, but i hooked it up to my new psu (zalman 850), and sure enough, it said the -5v was bad. the stuff that came with the tester said that if a light failed to illuminate, that rail was bad. OK.
so i am sending the board back AGAIN, this time with the PSU.
so i have my old psu that worked fine before, so im thinking i can drop in my old board and old psu for the time being. i put the tester on my old psu jsut for the hell of it, and GUESS WHAT, no light on -5v. bummer. is the tester bad?? i have no idea...
if its not the psu,..... what IS it???
