CPU Failure? Computer gives no video signal. A friends "post card" stops at "get cpu type" has the board or the cpu failed? Or is it some thing easy to fix? ThanksDavid

    System has separate graphics - PCie. I've tried 2 different cards - both known to be working- and the post card still gives the same result from the Phoenix bios. Code is 04, get cpu type.
    Thanks

    Is the video "onboard" or a separate video card?

Try a different video card. Usually this problem is a defective or video card that has gone bad.

    Did you upgrade the cpu? It's possible the cpu failed or if you upgraded that you put a cpu in that is not compatible with the motherboard. Try reseating the cpu first to see if it's something as simple as the cpu not seated. Make sure you apply fresh thermal paste. Good luck.

A Comprehensive Guide on Computer Beep Codes. (AWARD BIOS)


When a computer is booted up its BIOS, it performs a power-on self test, also known as POST, to test and verify the computers hardware and to make sure all components are working properly. Here's a comprehensive guide on how to determine which component has failed on a particular beep code and give you an idea on where to start for troubleshooting.

The exact meaning of the beep codes depends on the type and version of BIOS that you have. The three most popular types of BIOS are those made by Award, American Megatrends (AMI) and Phoenix. If you are using a PC made by a company that writes its own BIOS, e.g. DELL, HP, etc, you will have to consult your PC user's manual or the company's web site for assistance.


Beep Codes for Award Bios.

iantechson.png

1 long, 2 short = Video adapter error

Troubleshooting: Either video adapter is bad or is not seated properly.

Repeating (endless loop) = Memory error

Troubleshooting: Check for improperly seated or missing memory. Reseat the memory if you can.

1 long, 3 short = No video card or bad video RAM.

Troubleshooting: Reseat or replace the video card.

High frequency beeps while running = Overheated CPU

Troubleshooting: Check the CPU fan for proper operation. Check the case for proper air flow.

Repeating High/Low = CPU failure.Either the CPU is not seated properly or the CPU is damaged. May also be due to excess heat.

Troubleshooting: Check the CPU fan or BIOS settings for proper fan speed.


I will be posting more tips on other versions of BIOS.
Hope this helps.

No signal displayed


hi,check the CPU of your computer if it is booting properly.you can try to push the caps lock of the key board pressing the keyboard once the LED light indicator lights up then press again the light will turn off .This means that the CPU boots up and functioning properly.Check the data cable connecting the CPU and the monitor there must be a broken line there you can replace the cable or you can re insert the cable a loose connection can cause the problem.IF all are good and still same problem try to re insert the video card from the main board make sure to turn of the power before removing the video card...try this solution and post back if nothing happens after doing these solutions..good luck!

The desktop won't reboot. The power light stays yellow. I hear a fan running, but the monitor says no signal.


If your fan runs and the hard drive spins up, then you have a video card problem.
I'd do this: Disconnect everything inside the case but the CPU, memory, and video. Now try to boot. Also observe the fan on the CPU--does it spin?
If this fails, then your video has probably gone bad. Also--does your computer usually give you a "beep" when it starts up? If so, is it giving you a beep now? If not, you're failing the hardware startup test (POST).
So, your problem may be the video card. If your video is part of the motherboard, then you need to replace the motherboard.

CPU Problems


What can also give the same symptoms as a doa cpu is bad ram. About the only difference is that you usually get a post code with a cpu problem and absolutley nothing with ram.

About the only way to check a cpu is to swap it out. They are not that expensive compared to a new pc unless you want an excuse to upgrade ;-]

Ram is checked by swapping it out or just removing and checking one stick at a time. Sometimes they just need to be reseated and away it goes.

Also check the power supply. If it has overheated or dired etc nothing will work.

Once you have checked out those three you will know if it is worth fixing or junking.

Do you ear the fan running when you start?
if yes the graphis card might be dead. if you don't have a graphic card (on the mother board) CPU dead or mother board any way ...bad signs

Pc starts and runs but wont boot up monitor shows no signal


1) When you turn on the computer, watch and listen for:

a) power supply fan, (power is on)
b) chassis lights (power is on)
c) ticking sound during memory test
(the BIOS POST is running)

d) beeps or rhythmical error codes
(POST failed, bad CPU, CHIP set, memory or video)

e) Monitor either comes on, displays garbled video,
displays a No Sync or No Signal message...

No depending on how far it gets:

Check power supply, cables etc.
Check video cable.
Check monitor with a different PC

Now unplug the power cord, with the computer still
on, this will help drain any internal capacitors.
Wait 5 minutes, then shut off the switches,
and open up the box. try the following,
one at a time:

2) Remove all I/O cards except the video card,
and don't plug them back in until the problem
is fixed. Unplug all the ribbon cables from
the mother board as well:

Hard drives, CD drive, floppies etc.

Make sure you make notes about how to plug it
back in, and cable orientation !!!

0) Re-seat all power cables: Red, Black Yellow harnesses.

1) Unplug and re-seat the video card

2) Similarly, re-seat all memory SIM/DIM modules,

3) Re-seat the CPU

4) Replace the video card

5) Replace memory, CPU or whole mother board,

Plug the good parts back in one at a time,
and test the machine.

Save for the power supply, there really is NO way to test
and isolate a bad module except by swapping/ trial and error
because of inter-dependencies.

For example a bad I/O card, any I/O card, can short circuit
the I/O bus, causing all other plug-in cards to stop working,
or even the main mother-board to freeze during the POST.

A bad power supply ditto.

A bad memory chip ... ditto.

The type of electronic instruments required to actually
test modern computers running at Gigahertz speed cost
hundreds of thousands of dollars, some cost millions, and
are only available to hi end manufacturers

Even the power supply will not power up for a voltage check
if the mother board is bad, although you can use a jumper
on the green wire to ground to force it on, when you unplug
the power connector from the mother-board, if you are brave.

Computer shops carry a lot of spare parts, and their service
department has gutted computers rigged up as test jigs.

They trouble shoot your system by either plugging your
stuff into their jigs, one at a time, or by plugging known
good components into your computer until the problem
is fixed.

This if of course possibly dangerous, since one bad part
can also fry other good parts that plug into it, or that it
plugs into. The compute shops, of course charge you
enough to make up for this.

If a computer is partially operable, it is also possible to
run software diagnostics.

If not, swap and pray is the only way.

Hope this helps
