Re: dell pc dimensio 5150 wont boot up
Try unseating and reseating the connectors from the power supply that are going to the motherboard. If this doesn't work then take out the memory from its slots and turn on the computer to see if it at least beeps without the memory in.
If it does then put the memory back in and turn on the computer then and see if the light is green, if you still only get a yellow light then your power supply is bad and would need to be replaced.
If the power light is blinking amber - The computer is receiving electrical power, but an internal power problem might exist.
Ensure that the voltage selection switch is set to match the AC power at your location (where power cord goes into unit).
Also try simply unplugging the unit from the wall outlet for a minute then plug it back in and boot it up.

first to get a properly bios you need to get the whole description and download it to an floppy disk if it does if not try to boot from a cd...theres a hirens boot cd tools to fix since you already flashed wrong i assume you have some experience use the key tag of yor dell to get properly drivers...
check if your booting device is working fine...
and see the booting device in the BIOS..
if it is not found there, try connecting the same in other PC as a slave..if there also it does not work, the device might have gone
While the system begins booting --before the xp logo shows, if it gets that far for you, hold down the F8
key. This will bring up a menu. Choose "start windows in safe mode with
networking". The OS will start in safe mode. run a virus scan,
defrag and scandisk, then restart the system. If is still wont boot
normally, do the same thing then run a registry fixing program such as
uniblue registrybooster, then reboot. If it still won't boot you may
have to format the drive and reinstall the OS. good luck. PLEASE RATE THIS ADVICE WITH
SOME THUMBS UP!!!
Most times when you have flashing yellow light there is issue ether with cpu or motherboard. Just to be safe test the power supply and if ok then try to replace cpu and go from there. If power supply issue just replace it. Might be easier to take it to pc repair store. Good Luck
Don't know how old your machine is but the most common cause is a bad power supply. Some have had success by removing the CMOS battery and after replacing it have gotten their machine to boot up but in almost every case, the problem returned and the culprit was the power supply. Depending on what you're willing to spend they run from $35 and up. Best of luck and pleae post back with any other questions.
Well, this is the problem since quite a variety of problems can trigger the error.
1: the bios can be malfunctioning (a bios reset or flash can give a solution) 2: the cpu can be malfunctioning (this requires a new cpu) 3: the cpu socket can be failing (this requires a new mb) 4: the problem can be with bad usb sockets 5: even a bad uplink to a usb hub can cause this error to appear. Did you change your monitor lately? I would chase down the USB things first...that and the monitor seem to trip the trigger... Hope this get you started- I think you were right on target with the flash of the BIOS-try it again using the BIOS flash downloaded from the dell site...and to run the chipset again...it just might Good luck my friend, hope this helps, please leave rating, thank you kindly
