Question about Dell Dimension 5150 (DIM515MIN) PC Desktop

Blinking yellow power led

I have a similar problem to the one you responded to. When I press the power button to power up the power led then starts blinking yellow, but the computer does not power up. If you then wait some time - 10 to 30 minutes the blinking stops...hopefully! Then when you press the power button again it will power up and work fine. What is wrong and how do I fix?
Thank you

    No LED's indicate a problem and the Dell site doesn't help. Won't even accept an email from me as a customer!

    I have exactly this problem - thought it was connected to the XP Service Pack 3 update and re-formatted the disk and re-loaded Windows with service pack 2. Exactly the same!! Sometimes it boots if you pull out the USBs first but the problem is getting worse and this morning, I had to wait 20 mins until the blinking orange light on the switch on button stopped and then it re-booted staright away normally. My computer is just two years old - have re-seated all the cards / memory modules but just the same, as it will be if the problem is a failing power supply

    After about two year, the power button blinks slow yellow and the PC will not start unless the CMOS battery is removed and reinstalled. The PC then starts up fine. I get a "Previous fan failure" message", but both the power fan and the CPU cooling fans are running. The Dell site forum says technicians can access DSN #341244 and I likely need a new front I/O panel ($88), power supply ($77) and mother board ($140). Dell will sell them to me for $305 total so I might be better with a new PC. The front I/O panel is redundant to the rear inputs.

Check at the back of the tower you would find 4 LEDs(small lights) labeled ABCD in a row or you might have 1234 on the front panel. note the status of these LEDs when the problem occurs and check for the solution accordingly on the support.dell. website.

would also suggest to disconnect all the devices (keyboard mouse printers etc.)next time the problem occurs and then try to start the computer

What causes red led on starting?


Remove Power Cord then press and hold the power button for 30 seconds, then put the cord back in and try to start it.

When you press the Power Button are you hearing the fans run, the disk drive running, the cd drive click and the light on it comes on for a second or two?

Anything shows up on the LCD Screen?

If you press the power button and absolutely nothing is happening then you most likely have a bad power supply.

If you press the power button and you start hearing beep sounds or blinking lights in a continuous pattern (ex. 1 long followed by 2 short) then you have a motherboard issue. Those beep sounds and blinking lights tells the technician what is going on with the computer.

*Unplug the power cable from the back of the system. *Press and hold the power button for at least 5 seconds to discharge remaining power.*Inspect the voltage selector setting on the back of the machine (Figure 1). Ensure that the voltage select is set in the correct position for the region the in which the system is operating: For Europe and Asia, the voltage setting should be 230V.In North America, Mexico, parts of Central and South America, and parts of the Caribbean, the voltage setting should be 115V.*Plug the power cord back into the back of the system.*Turn on the power.
STEP: Try a Different Known-Good Wall Outlet.

Computer won't start up


sounds like the cpu is dead, if your fan was full of dust theres a high chance it wasnt working properly for a while which would of caused the cpu to fry from lack of proper cooling and also the dust in the vents would have prevented heat from escapeing so its highly probable that the cpu is dead try replaceing it, i cannot gaurentee that anything else internally got fried from the heat tho, i had a similar problem a week ago

I replaced the video card and it still will not boot up.


IF A&B are yellow and C&D are green it indicates a memory error.

If A&B are yellow and C&D are off then it indicates that the computer is in sleep or reduced power mode.

What was your symptoms before you replaced the video card? Sometimes if the power supply is weak or bad or you have a bad motherboard then you get no video output. Check your cpacitors on your mobo for leaking or swelling. Let us know what you find out.
