no boot,no leds, but fans spin

[garpie]

With over 5000 threads here, this one may have been covered...

My aunt's computer stopped starting the other day. Previous to that she'd had a lot of problems with programs hanging- and I recently replaced the powersupply.

Now, turning on the power has the following results: the PS fan, case fan and CPU fans spin. And that's all she wrote. No HD spinning; can't open CD/DVD drive; no LED's; no display.

I have tried: reseating everything I could think of, removing expansion devices/cards.

What could this mean? What do I do? Is this maybe a CPU issue (AMD overheat)?

Thank you kindly.

Why did you replace the power supply the first time?
After you replaced the PS did things ever work?
Some info on the system and the make and output of the new PS please.

I suggest my canned spiel for initial builds:

For new systems it would be wise to barebones boot the system initially. This is best done on a non-conductive surface such as a piece of cardboard on a table.

Connections from the case/power to the motherboard are accomplished outside of the case on the table.

Barebones is only the RAM, Video Card, Monitor, P/S 2 Keyboard...and of course the CPU>Heatsink>Fan...

See if you can make it through POST with this barebones approach...

Reboot, setting the BIOS to boot from floppy first...usually, the (0) choice, save and exit...shutdown.

If this worked add the floppy drive.

If the system booted again successfully, shutdown and reboot using a RAM tester such as: http://www.memtest86.com...these are self booting.

If all is well, shut down and add the harddrive. If the reboot is successful recognizing the harddrive, I then shutdown and reboot using a floppy with the Harddrive's diagnostics (downloaded from the manufacturer's site)...these are also self booting...

If all systems are go, proceed to add an optical drive capable of loading your operating system...

The concept is to load one hardware device at a time which provides for troubleshooting as well as assembly of the computer.

As I actually suspected, the CPU was burnt.

Thank you for all your suggestions.
