I have a Dell Precision 370 desktop tower that won't turn on. When you push the power button it won't do anything. The fans are not spinning, the leds are not burning and nothing happens. The led on the motherboard does burn when the powersupply is connected to the power source. I got this computer from a friend and he said that the computer worked just fine before he gave him to me.
What I already tried:
-I unplugged everything from the motherboard except the fans, the power supply (from PSU and from the button) and the graphical card (couldn't get it off the motherboard)
-I tested the PSU with the paperclip-test and it worked fine
-I tried to power up without using the button (by connecting the pins on CTRL PANEL pin board). I'm not completely sure I did it properly and didn't connect something not needed in between, but I tried to connect every pair of pins with a piece of metal. It didn't turn on.
-I removed the battery on the motherboard and put it in again
I believe I switched all switches on, and that my power source and wiring should be correct and intact.
So my question is: is there a way this could be simply resolved or at least is it possible to localize the problem? Because if it's a faulty CPU or motherboard, I would like to know that. If it's something else (like faulty graphic card) or unproper connection something the computer might be "saved".
He said he used it just fine before the transportation, but when the computer arrived it wouldn't turn on any more. Last time would be like two or three days before the event I guess. I'm not sure if it was knocked during the transportation (I wasn't there), but I guess he would've said that if it was something big.
The computer is around 2006 I believe, maybe 2005 or 2007.
It appears to be the power supply. I had the same issue.
- Computer Worked Yesterday, but not today.
- With the power supply plugged in as normal the LED on the motherboard was Green and the power button did nothing. Same result after re-seating everything.
- I used a Power Supply tester, the little handheld one with green/red lights on it. The Power supply tested good and with the P4 connector still on the motherboard it would spin up the big cpu fan on the back of the case.
Just for fun I tested a brand new Power supply....... Now i'm back in action!
