Question about Dell Dimension C521 PC Desktop
I have a Dell Demension C521. It will not start even after I replaced the power supply. Any Ideas??
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.
