  • A7N8Xe Deluxe wont boot on 400fsb???

    OK very weird problem. I came home last night, turned off my computer using the start>turn off. I try powering it up this morning and it hangs on the POST screen. Im like WTF, so I try like thre more times, same thing. To make a long story short, the only way it boots is if i clear the cmos and set the fsb to 100mhz (x2). I WAS RUNNING 200x2 the other day no problem!! Also, in NVIDIA system utility it sys the cpu is getting 1.85v? Yet in bios it says 1.65!?

    Someone help what the hell is wrong with this thing?!?

    Thanks
    Dan

        Saw this problem recently. Cheap psu deteriorated after about a year. Problem appeared when it got warm in the Spring. It tested OK with a basic tester, but wouldn't boot the system. New, name-brand psu boots every time. Been installed about a month now.

          interesting, ya my psu is old as hell. But its a antec smartpower 400watt. Im pretty sure it has a lifetime warranty, and this problem did just develop when i moved from NY to MD. And the 80deg temp here has def increased operating temps. The computer puts out enugh heat to raise my ambient room temp about 10F. Ill swing by compusa and pickup a psu to see if it will fix it. I'll post my findings...

            Your psu should have a 3yr warranty. All psus degrade with use. All suffer performance drops with rising temp. I use Antecs all the time and like them. They last a long time compared to el cheapos, but they do wear out.

              With the fsb at 400 it boots to the post screen but no further. If it were the psu would it even start?

                Without actually going in and swapping out components, nothing is 100% sure. In your position, it's one of the easier things to swap out and probably one of the less expensive choices.

                  Yeah thats so weird, it must be the psu cause ive been running at 166 x 2 all day no problems, only when i try to juice it to 400 does it seem to lack the power to boot or somesuch. All this stuff is brand new with the exception of the power supply (2 years old) so i would have to agree power supply is lookin mighty guilty....

                      Had another thought! If your bios allows it, try bumping the ram voltage by .1 volt.

                        Ok I got a new psu and its working at full speed now. For some reason when I enter games using directx the 'bios voice' comes on and says 'SYSTEM FAILED CPU TEST' over and over. The game runs fine but the voice keeps saying that. Ideas?

                          Why are you running PC2700 when you should be using PC3200? :confused:

                            I think its okay if he runs PC2700...
                            But must be non-ECC DDR SDRAM memory...

                              WTF? :confused:

                              I have yet to see an nForce2 mainboard that uses ECC DDR memory.

                              The point I was making is because of the trouble that he's having at running a 200MHz/400DDR FSB and if he's trying to run that memory insync then the memory is being run well over spec (PC2700 is rated for 166MHz/333DDR use while PC3200 is rated for 200MHz/400DDR use). Sure you can run the memory slower than the FSB but is he running the right memory settings?
