Cold booting Help?

post #1 of 4
Thread Starter 
I have a computer that is a few years old, and i had an issue starting about 6 months ago where i had to unplug it wait til the green power light on the motherboard goes off and plug it back in and it boots fine and stays on without crashing. Well now I havent used this computer for a couple of months and I am getting ready to sell. I have to fix before I sell. What does it sound like the problem is? (another thing that also happens is the keyboard when i plug the led keyboard and the light is left on the keyboard it stays on even when computer is off, and willnot boot when led's on the keyboard are turned on). As the computer sits right now, its without harddrive and dvd rom so booting into windows is not possible.

Here are specs:
amd x64 4400+
antec true power 500 watt
asus a8r32 mvp deluxe motherboard

sounds like its something with the motherboard.

Go into the bios, and look for a setting related to wake up on keyboard (as this requires a large amount of amperage on the +5vsb line). It occurs to me that you might have an older power supply which cannot supply enough amperage on the +5vsb to power back on the system through the keyboard. You might notice it as a jumper on the motherboard (usually near the keyboard, but each board is different), or as an option in the bios, usually under power management or something.

Whereever it is, whatever it may be called, disable it.

I checked that it is off. I think it may have happened around the time i changed the motherboards overclocking to ai nos or something and after that it seems i ran into problems. Ive heard about changing ram timings in the motherboard and voltages and it being off and people unable to boot properly. What can I do to check to make sure that's right?

If that isnt a solution what about just buying a new motherboard, what's an inexpensive motherboard that will work?

well, for starters, perhaps its a good idea to clear cmos for now. Then input the basic settings again, dont play with anything advanced, just load defaults, setup your hardware, boot sequences, date/time if necessary etc, and see where that takes you. It is possible that you need to manually input your ram timings, although unlikely if you were always running default settings prior to changing to nos mode.

A good way to check your ram timings is to grab the ram and contact the manufacturer, or google, to see what timings you run at. My asus board tells me what my ram speed and timings are in the bios, so I will assume yours does too, if you ram is 4-4-4-12, then as long as its set to 4-4-4-12 *or higher* it should work fine. Just to be safe, set it to 5-5-5-18 if you suspect possible memory issues. If your ram is 800, set to 667 (just for now, for the sake of troubleshooting), if its 667 try 533 etc. Try different memory configurations, example one stick in one slot one stick at a time, switch sticks and slots and see where that takes you. If you ahve available resources, you could try testing new hardware, start with the motherboard, as thats the most likely cause, followed close by ram and power supply.

I linked a motherboard above, which *I* feel is a great balance of performance, and price. If you are looking for rock bottom price, and dont give a **** about quality or performance, then go with

http://www.ncixus.com/products/28444...ay%20Computer/

OR

http://www.ncixus.com/products/28608...%2FELITEGROUP/

the latter of the three is a AM2+ board, but it doesnt have a native 1066mhz memory controller. At least the buyer will be happy to konw they can at a later date upgrade to a quad core without hassle.
