Dell Studio XPS 435mt lights power indicator but won't boot

Dell Studio XPS 435mt lights power indicator but won't boot.

2 or so years old Dell desktop is down and not wanting to come back up. Fans are off.

When I press the power button, the power LED blinks orange, otherwise it's off. Windows 7, sp1 I think, 6 GB RAM

Are there any answers or advice for this one?

Hi Steven,

I would suggest you drain the residual power from the laptop. Disconnect any external peripherals (flash drives, printers, external hard drives) from the computer -> remove the power cable -> press and hold the power button for about 10 seconds -> reconnect the power cable and check.

If the issue persists, I would suggest you to remove all the memory modules and reseat the graphics card (if available) from the computer. Put one RAM at a time and check if there is any change. Ensure that you check in all available slots with just one RAM.

You may refer to the service manual . Please ensure to follow the safety instructions.
Please reply if you have any questions.

Thanks and Regards,
Appu S

I had same issue on my Dell Studio XPS 435MT, it was PSU

I had a similar issue. Power LED blinked orange. Holding down power button made the fan pulse like it was trying to start running but didn't have enough power. Following other peoples' advice on the Dell forums, I replaced the power supply with a higher capacity power supply (I used a Corsair CX430) and that took care of it.

Had same problem for a couple years. Fixed it, finally.

I got this PC for free. From time to time it just wouldn't start; power light on, ampler board light on but puch the button and nothing. Sometimes, after I pulled a USP cable out it would magically start, etc. Finally this unit just would start up. I bought this supply:

480W Power Supply for Dell Studio XPS 435MT N250K J860K DPS-360FB-1A PS-5361-2

from this seller on ebay: kdmpower

Less than $50, arrived in two days, new, with other wiring to cover other units.

PC now starts every time, no more issues. very happy.
