cold boot problems, won't post until turning off and on

[Guest maximus]

The one problem i'm experiencing is that during a cold boot in the morning, the machine won't post. If i turn it off, and hold down the insert key while turning it on again. It will post and boot just fine. I'm not sure if the Insert key is helping but thats what i used to do on my old abit board when it won't post due to too much OC. all subsequent powering off/on and restarting will be normal, its just the first boot in the morning that it will not post. i'm thinking its got something to do with the temperature. any ideas?

 

i'm using the 10/15 bios with the cpu at 275*9

:confused: ...pushing 2x512 of Ballistix PC4000 and using a 460Watt AgB power supply with 'good' dang rails> I had cold boots quite often and yes I was well over-clocked. Hehehe. Anyway I wanted a power supply where I could adjust the +3.3V ( Fortron 530 ) rail so I could swap in my 2x256 BH-5 and run it overclocked and see how it worked knowing I needed the tweaked +3.3V rail which is right now sitting on 3.60V> but anyway since I have put the Fortron 530 in > NO more cold boots. Humh? And you would think the power supply you have would be fine. Even thought to get one myself until I found it had no adjustable +3.3V rail without modding. But my 460Watt AgB supply always had good rails but you could "hear" that sucker groan when I started to bench or push the board> I never hear this Fortron utter a whimper and no cold boots either. Strange!

I will check the rail tonight when i get home. How do i check the 3.3v rail with a multimeter? is it from the little floppy power connector?

Use your MM and look for the 20 pin power plug on the

Mboard.

 

Ease into a yellow wire connection. Yellow is +3.3V rail.

 

Green is +5.5V rail .... Red is +12V rail.... Blacks are ground

 

A digital MM works the best 'cause it'll give you a read-out. The

needle and scale type will work and are better than nothing. But

they don't really read down to the nubbin' of things. Get you

in the ball park tho.

 

Luck.
