HI, my packard dell tower pc won't stay on when I switch it on. Stays on for about 3 second at most and it switches off by itself. The light comes on on the keyboard as soon as it is on. If I disconnect the CPU cable the machine stays on, hard disk, fun are working but nothing happens on the screen. Can't figure out if is the CPU or motherboard gone. Motherboard is mcp73vt-pm. Thanks for your help!

Sounds pretty desperate. I suggest you find the Dell boot disk and insert it before switching on. Then come back here to report progress. Wish you luck!

the flashing green light is ethernet.

Take it back, this is a manufacture defect.

Wow a Packard Bell, it's got to be old. I would bet your power supply has burned out.

Try another Monitor

May be a problem with the signal of your graphic card, or your pc it's in standby mode/suspension.Pay atention when you switch on the pc, if you listen any "beep" from the tower. There is a beep code table wich tells you what's your problem: RAM memory, graphic card, motherboard...

Hi this is due to static

do the following

1) Unplug all the cables from the back of the computer tower and monitor including the power cable.

2)press and hold the power button for the tower for 30 seconds do the same for monitor this will release all the static.

3) put back the cables and then try

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.
