Pretty Much General basic troubleshooting.

  1. Disconnect all external connections except the power, see if error changes. If it does, connect items 1 at a time till issue is isolated
  2. Remove all Expansion cards, see if any change
  3. Disconnect all drives from MB and power supply, see if any chage.
At this point if nothing has changed, replace the motherboard.

It will not start even after I replaced the power


Before anything else, open your case and make sure all power and data cables going to motherboard, disk drives, etc are firmly seated, and remove and re-install memory sticks in the same locations. Sometimes temperature changes inside the PC can cause these connections to loosen. If that doesn't fix it, do you hear the noise of the cooling fans coming on? If you do, check your monitor for a green light. If you get a green light on the monitor and fans are powered up and running and you get nothing else it could be a hard drive issue. Try booting from CD in that case. If fans come on briefly and then shut off, or fans stay on and you have no green monitor light, this could indicate an issue with your processor or motherboard.

Dell C521 Power Issue


I would replace the power supply and if that does not help (after battery replacement and power supply), the ram could be faulty but usually faulty ram will beep a code. If ram has no avail i would suspect the mainboard and replace. Good Luck

I have a dell C521 tower,switch it on but light stays on orange,fans work but it wont switch on.help.


Hi,
if the light remains Orange, Possible In Standby/Sleep/Hibernate Mode.
Try pressing And Holding The power Button For 4-5 seconds Or more.
If this Fails, remove the power Cable, remove side-panel ( Unless Warranted ) locate the silver cmos battery, on the motherboard. remove the battery for 10 seconds, replace and repower and startup. failing this i,d suspect the ram/memory or cpu.

check on system lights... what are the diagnostic lights telling you??
if the 4 lights are off you may have a problem with the led itself or the powersupply is just messing with your head.

Amber Light and fan running


1st thing, disconnect everything but keyboard mouse and monitor, see if anything changes.

If the issue persists, ensure that all power and card connections for the motherboard are tight and secure. If you've added RAM or other parts, remove them. Reseat the RAM in the motherboard that came from Dell.

If none of those ideas have any effect on the issue, replace the motherboard.
