It may be your motherboard that is failing. Your LEDs and fans turn on but do you see any lights on your motherboard, or do any of the fans on the CPU start running?

I have a Sunblade 1500, recently it just stop working. The power led is on but no output in the monitor. It supposed to beep onces to notify the user that the sytem is coming up, but no beep can be heard....

Is it possible to try the monitor on another computer? If so try that. I've worked with motherboards that don't give a power up beep code (strange, I know), so after the checking the monitor, I would try removing and re-seating the video card, and memory, one at a time and see what happens. Is the cpu fan running? Check these things out. Is there onboard, integrated video in addition to the graphics card? If so, try using the integrated video port. If the cpu fan is running, and the power led and hard drive leds are working, then it's a safe bet it's not your power supply. It would have to be the video card, in my opinion .

I have a hp a350 cpu.the problem is that the light of led has gone red,as before in working condition it was green. It can't start.the power to hardisk is also not coming.please tell a sollution.

As you say has become red and no power to the hard disk.
First check the power cable for any loose connections and check if it give power to the cpu and the fan placed on processor starts working as you start the power. If fan it starts and with in few seconds stops then your power supply/SMPS is weak or damage. So replace it for proper working of your computer. And if after power on all fines but red led on monitor and no power to hard disk Try to replace the hard disk power cables because they are not working because of it no operating system is detected and led of monitor is red. After replacing hard disk cables hard disk starts working and still no display or red led on monitor check the vga cable for loose connection or replace it.If you are using vga display from graphic card try to get display first from onboard vga slot.After it your problem will disappear and your pc run smooth and fine.

Emachine T6520 Wont Start Up

Check your num lock key status press it on and off if hum lock led is on and off when u pressing then your cpu working fine. so check connectiopn of vga cable cpu to monitor.
Also some times display screeen resolution issue so when u power up press F8 key then enter in enable vga mode then you can chang escreen resolution to 1024*768.
but if num lock key is not on and offf then open the cabinet of cpu then find cmos cell on mother bord and pull it for 14 minutes then check .

remove ram memory - it should beep when you switch it on - if no beep then check CPU in socket and cpu fan spinning when on.

Emachine Will not boot

different beeping patterns are codes which indicate what part of the hardware has failed (ram, video card, cpu, ect). the fan failure would not cause beeps, and would not cause the cpu to fail unless already in windows. if you could find out the manufacturer of your motherboard you could check with them about what the paticular pattern of beeps which you are getting mean.
