Reboot loop on cold boots in the morning.

[trickson]

When I turn my computer on in the morning every thing works ( turns on ) but the computer like keeps restarting in some kinda weird loop then finally it catches and all is fine . Only does it in the morning .
Any one know what the cause of this is ?
Gigabyte GA-EP45-UD3P MB here is what it looks like installed .

I am getting better RAM soon . But this don't seem like that kinda issue to me . I hope my PSU isn't going out . every thing checks out normal on my tester but it can only do so much any way any help is much needed . OH and in-case any one wants to know let me say this once .

I have not yet started any overclocking . BIOS settings are all on AUTO .

i'm sorry - idk. but thank you

How far into the boot up process does it get before it restarts? Does windows start to load?

I used to get this if i left my window open overnight..
I put it down to very cold H/D's or condensation inside my aluminum raptors..
My fix was keep the window closed it fired up everytime..
Not saying this is your problem but almost indentical

No not even as far as tunning the screen on . It just loops till it sorta catches .

Ever since my P35 board, on a cold boot the board fires, stops and restarts, then fires into windows. Not exactly sure why, but every board I have had since does the same exact thing.

IF it is cycling more than just the once I would be worried, if it is only the once, I would consider it "normal" operation.

Is it in a room that gets cold overnight?

I've noticed the same behavior with my 965P, P35, and P45 boards. Though it only happens when something is overclocked/overvolted/undervolted, I don't seem to remember it happening when everything was at stock.

something I just thought of more GB spacific....

if it is more than one cycle it could be the bios chip. I assume your board has dual bios?

The only time I have seen a multiple cycle is from the bios. If the clock is unstable it will keep trying to boot, or possibly a bad bios.

@ tekie...all of mine do it with a fresh CMOS clear or an OC.

Yeah it is 3-4 times I think but the MB has this Phase lighting on the MB and well according to that every thing is fine . the lights all light up and do just what they are supposed to do , then they just restart and do it all over again .

Yes very . maybe like 65*F or so .

have you tryed the latest bios ? mine never does that it always turns on the first time and ive had it on two psu's the one in my specs and ocz 700w psu

OH MAN I HOPE NOT !!! God this is the 3rd time with FRY's and this MB stuff ! MAN !
could it be the DDR2 800MHz RAM ? I mean it is old stuff and all . or a PSU issue ? MAN any thing but the BIOS being fried ! Yes it has a dual BIOS and I did update it and all .

You need a POST tester to find out where it's hanging/looping.

All 755 boards do a blip, then start, as this is nessecary to change some settings, implemented @ P965 chipsets. Otherwise the cpu would remain fully locked, or something. Can't remember why, exactly, but it had something to do with clocking the chips.

 

[sneekypeet]

I mean possibly a bad write of the first bios. What happens in the dual bios is if the first bios fails to load, it cycles like 3-5 times trying to boot said bios chip. When it fails to load that correctly, the second chip automatically kicks in and you can boot.

I suggest trying a flash to the latest bios using a thumbdrive formated in fat32 with the bios file on it. reboot the PC and hit the Home key to get into the flash utility, then search for the bios and load it.

 

[cadaveca]

Sounds right to me...make sure to go back to stock before flashing the bios though!

 

[sneekypeet]

agreed I did miss that important tidbit of info

 

[trickson]

OK I will go to gigabyte and get the bios from them and see what it does thank you . BRB .

 

[sneekypeet]

I had it happen on my UD6 when I grabbed an update...just didnt take right, and showed similar issues. Redownloading and writing the bios took care of things for me. Hope it solves things for ya.

 

[copenhagen69]

this happened to me on my ASUS board ... few weeks later it hit the RMA train because it was dead

hope you have better luck with yours ....

Before you do that, check the bios string and see which bios you are on (if you updated). Then once you are in CMOS push F9, it will display which bios is on what chip in dualbios. That can give you a heads up as to which chip you are booting from.

 

[DOM]

make sure you get the bios for your ver

 

[copenhagen69]

lol +1

otherwise ....

Good point Jr, but I think we are too late. CPUz would have confirmed my theory.

 

[trickson]

OK I am on gigabytes site looking at the bios updates there are 3 versions FD , FB , FA . I have FD now I will DL it and put it on a floppy disk then what ?

 

[sneekypeet]

I didnt use a floppy to flash, I believe there is a guide to GB flashing here have a look, its dated, but the theory is the same.

It's much easier if you have even a small thumb drive

 

[copenhagen69]

you can use a jump drive if you want



EDIT: ah sneeky beat me to it :/
