No signal from computer to my monitor???

[basil78]

I'm building a new PC (have done a few in the past, with ease!).
I've got a new ATI Radeon 9250 256mb AGP graphics card, Asrock 939 Dual-SATA2 motherboard, AMD athlon 64 3500+, and 1Gb DDR400 RAM. With 80GB IDE Maxtor HDD (formatted and new) and NEC DVDRW.

I know that the graphics card is sound as i tested it in my other PC.:)
I know that power is getting to the AGP Slot on my motherboard.:)
I know that the CPU and motherboard is recieving power, as to is the DVDRW and HDD.:)
I know that the monitor is also sound, tested on my old PC and works fine!:)

So why is my monitor not recieving a feed from my computer. All connections look good. I can't work it out, am I missing something??:confused:

Any help would be great, the quicker the better - have spent 3 hours just staring at the computer hoping it'll fix itself - alas that didn't work!!:banghead:

check in your bios and see which display is set to load first, it may be set to your onboard graphics if your mobo has it.ussaully when you install a graphics card, the onboard auto disables, but maybe in your case it didnt.you could also try plugging your monitor in to your onboard and see if it works.also chech to see if your chipset drivers are installed and updated...could also be that that g card is not supported with that mobo:wtf: does that card have a aux power conector?

try to boot from a pci card while the 9250 is also in.

[basil78]

I can't see my bios to change any settings, as there is no feed to my monitor. There is no onboard graphics so i cannot connect my monitor direct to the motherboard.
I only have 3 AGP graphics cards (no PCI ones) all of which have the same problem with the monitor - but when used with my old computer are fine - I presume it must be a motherboard problem? Anyone agree or have another idea??

Cheers

you are using the card on the old computer? and it works?

[basil78]

Yes. Graphics card does work on old computer when connected to monitor. That's what makes me think its either the motherboard or the RAM.
The computer does not beep on startup.
When i hit the on button I know the following:
Power gets to all components of my computer.
CPU and fan is working.
HDD fires up.
DVDRW is operational.
Monitor does work but no picture displayed??
Graphics card does work but no picture displayed on monitor??

Any ideas?

If you have two sticks off ram, take one out. I had this a few times and each time it was my memory modules either in a bad slot or just not wanting to respond.

So, if you have two sticks, then take one out and leave one in DIMM1 and try to see if it loads up, if it does, do the same for the other stick and try booting up with the second stick in DIMM1 as stated.

If both load up in DIMM1 then try both in together, DIMM1 and DIMM2, if that doesn't work, then maybe DIMM2 might be faulty, so then try moving the stick from DIMM2 into DIMM3/4 and try booting that way.

I hope you get this sorted mate, good luck!

Take out all ram, and turn on your computer. The PC speaker should beep (no memory). If it doesn't your motherboard or CPU is dead, it's usually the motherboard in such cases though.

You could also remove every non essential part and try to boot. So just use mobo+cpu+vga+1 memory module.

Get yourself a PCI graphics card, AGp port might also be defective. It could be quite a lot.

Took all ram out and PC did beep. I take it that this means the ram is dead?

Would be a fair guess. Can you test it in another comp? Or have any other ram o test the system with?

[basil78]

That is the problem. My old computer is PC133 SDRAM so can't test it in there and only have the 1 stick of 1GB ram so haven't got any more to test!
Vicious circle. But if you think that it is the RAM I'll go out now and buy some more to test??

[DanTheBanjoman]

Try to borrow some from a friend, that's cheaper :)

though if it's your last resort buying would probably work. Not sure how it works in the UK but here we can return bought stuff quite easily:)

try sticking them in one at a time because some ram dose not like some motherboards i had that problem with mine it just would not start though also are u using slot 1 &2 not 1&3 because that will cause stuff to happen so try that
