Blue screen STOP error.........hellllllllllp!!

[Harrybaws]

Upon booting up WinXP, I get one of the dreaded blue screen errors. The message is as follows, "STOP:0x0000007E (0xc0000005, 0xf8342380, 0xf8991898, 0xf8991598)". I then have to restart and it boots up on the second attempt without any noticable problems.
Now i've looked around,on other help forums, to find out what the error is all about. It appears to be ....."Stop Error 0x0000007F is an Unexpected_Kernel_Mode_Trap"......"Refers to possible Hardware failure, most likely a memory/CPU problem. Either defective memory chips, mismatched memory modules, or even an overheating CPU. Overclocking a CPU past stable operation can also generate this error".
Ok, a while ago i was getting an error message, on startup, from the speech POST reporter. It said "CPU failed due to system overclocking". This message went away after a few reboots and i thought no more of it.
Knowing this, i now think my problem lies with CPU overclocking, despite the fact i've not changed the BIOS settings since new!.
My MOBO is A7N8X with an AMD Athlon 2700+ (2.17GHz) and 512MB DDR(333Mhz). Could someone please tell me what the settings in the BIOS should be for a stable configuration??. Any help would be greatly appreciated.

P.S...if you reply, regarding the BIOS settings, please explain in detail. I'm clueless about most of the settings in there :P. Thanks.

Anyone awake yet?

have you tried loading the fail safe defualts in the Bios?

[Harrybaws]

I'd have assumed that the fail safe defaults were the factory defaults??. As i said, i've not touched any of the settings since new and the system is less than 5months old.
Anyone have ideas as to what settings i should be adjusting to try and correct the problem?.

Yes, load the "fail safe defaults" in the bios.
Then, if you have your processor overclocked at all, set the FSB speed back to 166 mhz, which is the stock speed... Hopefully that will fix it.
I overclocked my xp1800 a while back to xp2000 speeds and it gave me an error like that.
Putting everything back to default in the bios fixed it.

FSB is set at 166MHz and i think the fail safe defaults are applied??. It's all set to "optimal" which is described as stable...with the other choices being "aggresssive" or "manual".
I'm gonna try a manual setup since the problem still exists. Does anyone know what the manual setup should be for my system?.
One more thing, the CPU temperature sits at around 55C......is that normal?. Thanks for anymore info people, it's all appreciated .

Hi Harry !
i have a very similar problem since a few days with the some mobo Asus A78NX and a 2500+ barton CPU. I never overclocked the system and suddenly have the prob that on the first cold boot the stopcode occures. The second start in normal mode works fine....; Very strange because the system ran stable for a couple of month before. I did a system restore a few days ago with settings that ran before without a hitch. No changes to the system were made...; My CPU Temperature is about 52-to 55 degree normally like yours. I will change the bios settings now and will post my results soon. greetings ;-)
