No display signal

[+TheGoddamnedKamina+]

So after replacing both my processor and power supply, my PC which wasnt even starting before at least boots up now. But both my motherboards integrated VGA port and my graphic card's cpu dont show a signal

Ive tried it with different cables and on 3 different displays but still no luck. My question is if my motherboard or graphics card ( or both ) are broken. Or if its something else entirely considering my PC boots up normally

Make sure all connections from power supply to motherboard are connected.

Sounds like your missing the one P4 near the processer.(4 or 8 prong).

Also do you have a speaker hooked up to motherboard to hear beeps? Sounds like you don't.

Good Luck...

what cpu did you put in what board?

Thanks for the replies!

I've made sure everything is connected and tried both the 4pin cpu connectors.

My motherboard is ASRock 960GM GS3FX and the CPU is an AMD FX-4300.

And im not sure if it boots normally but the cpu fan, power supply fan and graphics card fan go on normally.

Thanks in Advance!

you may need to update bios on the board for the fx4300
put in the orig cpu and update bios, then try again

http://www.asrock.com/mb/overview.asp?cat=CPU&Model=960GM-GS3%20FX

that is a very weak fx board
its a plain 3 phase board, (that design was for am2 cpus, should have under a 95w limit)
http://www.overclock.net/a/about-vrms-mosfets-motherboard-safety-with-high-tdp-processors
its rated at 95-125w because it will throttle under load

odds are it didnt fry the vrms if it powers on fans/leds ect.. while the 4pin cpu power plug is connected

if it will not spin fans or turn on lights with the 12v cpu power plug connected, it fried the vrms and you will need a new mobo

Aah the whole reason I had to buy a new cpu is that I broke a lot of pins on the original one. Is there any other way to update the bios?

[_I_]

buy a cheap cpu, sempron 130-145 are dirt cheap and will work to update bios

or do you have a friend with a low power am3/am3+ cpu
(95w or lower)

[+TheGoddamnedKamina+]

Hmm okay I'll try that. So if the fans are spinning it isnt likely that my motherboard is fried?

And what if I get a weaker CPU and it still has the same problem? What else could it be?

Did you uninstall the integrated graphics before installing the graphics card & plug the monitor into the graphics card? Some people make these mistakes. Recheck that everything is hooked up properly. You might need to reinstall the CPU and make sure no pins are bent etc. If all else fails then you might need a new mobo.

How does one uninstall integrated graphics??

[Joker]

You should of uninstalled the driver in Windows Device Manager or Programs and Features, power off the PC, install the graphics card in the top PCI-E slot + power cables, power on the PC and then install the graphics card driver.

lol, no

without the gpu installed, go to bios, change the default video order to pci-e -> onboard
turn off the pc, install the gpu
plug the monitor into the gpu
then turn on the pc again

They will all work on a dead mobo, if the speaker works you should get a single beep just after power on that tells you mobo passed bios check, rapid beeps indicate memory fault. If you get no beeps and no bios display then i would think either mobo is fried or cpu is dead or both.

Faulty RAM or improperly inserted RAM can also cause the no display signal issue.
And also make sure the RAM you have is supported by the motherboard.
