If the red light on Compaq Evo D510 P4 keeps on blinking and the PC wont start when you try to power your PC then whats the problem ?


Power Supply.

Weak voltage power rail, or more than one.

(There are three power rails for the Power Supply used in your computer;
1) The 3.3 Volt power rail
2) The 5 Volt power rail
3) The 12 Volt power rail.

Wires with Orange insulation carry 3.3 Volts
With Red insulation carry 5 Volts
With Yellow insulation carry 12 Volts.

Each wire is connected to one power rail in the Power Supply.
{All Black wires are Ground wires}

The Power Supply in your computer is an SMPS. Switched-Mode Power Supply,

http://en.wikipedia.org/wiki/Switched-mode_power_supply )

I don't know what form factor your Power Supply is because you didn't state which model it is.
Small Form Factor (SFF)
or
Convertible Mini-Tower
or
Ultra Slim Desktop

Post additional questions in a Comment. Also state what model your Compaq Evo D510 is.

Simply blink red light in front or power led light ,no display anything .power on button is on blink red


Try to do a Hard Reset. Disconnect all peripherals connected from the unit (power adapter, monitor, keyboard, etc) then press and hold the power button for around 15 seconds. Plug everything back then power the PC on.

Hope this help. Goodluck!

Short beep and red light


Did your Bios Battery Die?

5 short beeps = BIOS recovery successful

Usually means bios has lost settings some how. You have have more significant issues if there was a power surge.

My Compaq EVO d510 SFF won't boot, it does only about 5% of the time and when it does nothing appears on the screen, no sounds, the fan and everthing runs, the screen works and all cables work so any help?


1. does it at least turn on? do you see lights?? if you don't chances are you may need to replace the power supply.
2. if it does turn on.. do you hear any beeps.. could you describe how many beeps, how long are each one of them, if you get beeps, it's the motherboard usually letting you know about a hardware problem.

3. if it does turn on and no picture, (not even the very first picture with a motherboard/video brand/computer manufacturer) you may have a video card problem. I suggest you start replacing that item first.

hope it gives you an idea on where to start looking
good luck!

Boot pc problem


You can solve this by going into the bios setup & changing the boot order. Make the dvd/cd drive 1st in boot line then hdd. This should allow you to boot up from the windows xp disc. Hope this helps & please rate this solution fixya. Thanks.

Booting up


one light is for hardrive activity , the other is to show the power is on.. the flashing one is most likely the power light as most computers will tell you when thier ill....the beeping is an error code and should be in some pattern EG: Power LED blinks red twice, once a second, followed by a two second pause. Or something like that. Take note of the pattern and repost it here, then we can give you a specific area to look at.
