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.

Does not display out although Monitor is working fine after checking ram,display card


if the power suddenly went from your board it may have caused a short circuit and effectively killed the motherboard. my suggestion would be to get hold of another motherboard and see if you can boot. if not then it will most likely be your RAM. but since you said the CPU light isnt on at all, it will most likely be a dead motherboard

Compaq evo 510 Won't power up.


Could be bad RAM modules. Try swapping out the RAM in the system with new RAM. Install one stick, in one slot. If it boots, that stick and slot are good. Try the stick in each slot to make sure all slots are ok.

Presario will not start


Hi, remove the left side of your case, turn on power and see if you can see a red or green led light on the board, if its not showing then your power supply is faulty. If the light is on then with the power off check the RAM chips are tight. if that does'nt work Then trace the cables from the front of the case, locate which is the pwr switch and unplug that, turn the poweron and then use a small screw driver and bridge the pins of the pwr switch. If this does not work you have either a dead CPU or a dead motherboard. Regards mistyman
