PC wont bootup until after on for 10min

By kyleknicks ·
Here's the syptoms: If i turn off the PC overnite, and try to turn it on in the morning... the power would come on..but the pc would not boot. it is not until after 10mins or so, after the pc is "warm", and after hitting the power button off and then on, does the PC boot up with the ram counter (u all know the numbers that tell you how much ram you have).... if i reboot the PC, it works fine, but it is after a long "off" time, that it is not working correctly.

I am wondering if any of you tech's out there would know what it is, without me pulling apart everything from the motherboard to the harddrive to troubleshoot this.

Thanks

I have seen this one time before on an old system. There is a connection somewhere on your computer that is not getting connected, when it is getting cold it contracts. When it gets hot it expands, thus getting the desired connection. I really do not think there is a way to trouble shoot this except for singling out the guilty party by removing components one by one or by simpley reseating everything!

That "RAM Counter" is one of the first phases of the Power On Self Test (POST). Even before that, the first thing that your PC does is it sends a signal to your monitor and turn the monitor's power light from amber to green. If it is even turning the monitor's light green, you have a power problem. Try plugging the PC into a different power outlet, unplugging it from a surge strip and plugging it directly into the wall, even a different outlet. Try a different PC power cord. If none of those change anything, it's probably time to try a new power supply within the PC. If you've never changed a power supply, the most important thing is documenting EXACTLY how everything's plugged in.

It would be nice to have more information on the PC configuration.

I have seen similar problems on Socket A motherboards. The fix for them is setting the CPU speed manually in BIOS settings.

If this is an older system, and just started doing this, I would try;
1. Reseat all plug in cards and RAM modules.
2. Replace the power supply. It is possible that one of the voltages is not coming up right away.
3. Do the drives go through their self test right away? If not, try disconnectingthe drives from the MB, and see what happens.

I have also seen boot problems from cases that don't allow the AGP card to fully seat in the AGP socket. I test this by removing the bracket from the card, and seating it into the socket.
The fix for this is taller standoffs to mount the MB to the case.

It sound like a power supply problem to me as well. I say this because I was having the same problems turning on a cold PC too. When I looked inside I saw that the white power connector looked much more yellow on one spot and I decided to turn everything off and have it looked at before blowing my mobo or anything else. And by the looks of things I made the right decision. Hope this helps and please "unplug" everything before you have a look at yours. The Power Supply is nothing to fool around with. Best of luck.

after it does post, go into the bios setup, make it so the harddrive and cdroms are not on auto and that it would already know what to look for, the ones with nothing turn off, make it quick boot so it wont check ram, and make sure your hard driversand cd-roms are not on cable select - put it on master or slave.
