pc won't boot - Page 3

14th July 2004, 06:48

i took the mobo out of the case and tried it, but it did the exact same thing. i've tried booting with everything connected then took off everything one by one checking all the way. when i got down to the barebones installed (cpu, ram,hard drive, and video card) it still was doing it. so i tried without the HD and then video card, then ram, and then cpu.....without the cpu it works, atleast it doesn't do the reboot loop, but i it won't do anything more, no monitor, no BIOS, no nothing, it only stops rebooting. also i noticed the the POST code changes from "C1" to "F" not "FF" as in a normal boot, but one "F", i can't find anything in the manual for that one. taking the ram out doesn't seem to change anything so i don't think it's got to do with the ram. i hope that it's not the cpu it's a $230 P4 3.0 Prescott and i don't have a extra cpu to test it with nor do i have any spare ram. what do i do now?

What are you trying to say? May be you're too tired.

My Prescott had popped two PSUs insofar. Get a good solid Power supply or borrow one from a friend.

well i'm definatly tired, but i've still got to get to the bottom of this. i'm asking if it sounds like my cpu died or if it's my mobo. i don't want to buy a new cpu if the whole mobo is toast. i put a volt meter on the psu and i've got clean power coming from it so unless it's a crazy glitch in the psu, i'm guessing it's the cpu. also can anyone make sense of the POST code or where can i go to get more info on it? and i'm going to bed so i won't be so tried

well i've replaced both the cpu and the psu with no results
this sux.... i'll bet it's my mobo....any chance it could be my ram? what happens when it goes bad? chaintech support is being helpful and responsive, but they're really only telling me to try replacing parts one at a time which is getting very expensive!!!
anybody got any ideas?

thx
