Hello. I got a Dell Inspiron 545S a long time ago from Bestbuy. It worked very well for the longest time until one week I left it at my grandparents house because my cousins were visiting. My oldest cousin tyjhe was the only one to use it, but didnt use it on the day it stopped working or any days after. I came by to get it 2-3 weeks after I had left it there. It would not turn on. This has happened before with my old computers due to power surges, so I asked my grandparents if they had a power outage. They said yes, and that my sister had to replace her PSU. I'm not sure if this is during when my computer was left there though... and this happened about 5 months ago, so im sure no one would remember.

I investigated the computer furthur. When I held the power button it did nothing but inch the fan a tiny bit, and flash both the light in front of the desktop(a orangeish color, but the orange color only flashes, and is NOT there when i plug in the PC, only when i hold it, it flashes every id say .5 seconds) and the green light in back. the green light stays on in back when power is plugged in, and a few seconds after it is NOT plugged in. And it flashes in the same way the light in the front does, except it turns off for a millisecond instead of turn on.

Ok. So I figured it was a power surge. So I tried all methods of draining power, giving power, etc. Including the hold power button when not plugged in method, and change voltage method, which worked on my previous computers that had this problem. None of those worked. I waited a few days with it plugged in then tried. Didnt work. Waited a few days without it plugged in. Didn't work.

Now to give a good status of any modifications with the computer : I bought a graphics card for it, and it was too big to fit with the side cover on, so the side cover is gone now, and the wireless card that was taking up the only available slot is gone. The graphics card worked 100% perfectly, and there was no sign of overheating and no damage was done to the inside of the computer. No liquids were poured on it, and visually there's no damage whatsoever.

It is now 3 months from when I last looked at it, and im trying it again. Now, I finally notice a orange light on the motherboard, that works exactly like the green light in back of the computer. This orange light is located behind the DVD-CD drive thingy. There is a difference when I hold the power button now. Now the fan actually spins for a second, and before it completely stops, it spins again most times. This all happens when i hold the power button. The orange light didnt blink before the fan actually spun though. Before, the fan only twitched. I presume this means some sort of progress. And the fan spun a good 5/10 times the power "tried to turn on" while holding the power button.

Ok, so I read online for basic power problems, and I look for my pc specifically, but no one seems to have the same problems. But I do what they recommend for other problems, just to try it out. I unplug ram, and try with different ram combinations. I tried them all. Didnt work. Unplugged all wires and secured them back in. Didnt work. Tried with and without graphics card with same results. didnt work. I noticed that after i did all this, the rate increased from only half the time of the fan spinning to now 100% of the time fan spinning with each power cycle. This is my current progress. I'd really like help, as I'm sick of using this laptop with low memory and low graphical capability.

Please give me recommendations. So far I've only thought of possibly buying a new PSU; But only found the SPECIFIC part in bulk at a quote for price basis. BUT; I found a model that was used for Inspiron 531 : http://www.atxpowers...TFX0250D5W.php. Would this work if I absolutely HAVE to replace the PSU. and if it doesnt work, do they usually allow returns? If all fails, will Dell replace my computer? Please help, I'd really appreciate it.

One more thing : I recently had a usb device break in the USB slot, and I cant get all of it out. It worked before though, And the usb broken and graphic card never ever gave me a problem before this suspected power surge, or other issue. Thanks, just giving all the details you would need.

Hi Vultrex :D
The first thing to do is try another known working psu in the computer.
The stock components used by named brands are very rarely of good quality
and in particular the psus that they use, I myself find this irresponsible
because if the psu goes bad it can take the whole system with it.
You have done a thorough job investigating other possible causes and you
seem to know the psu is the culprit so why the delay swapping it!
From research it seems that a standard atx psu will fit so I have found a
psu for you to look at here http://www.newegg.co...N82E16817341022
If you click on the details tab it gives you the dimensions of the psu so
you can measure the space inside your case to make sure it fits.
Below is a link to some information on the inside of your case;

And below is a link to some information on the actual system;

Hope you find the above information helpful.
