Hi i just put together a pc, and it doesnt seem to output anythign to the monitor, the specs are as follows

AMD sempron 2800+ socket 754
winfast 760gxk8mb motherboard socket 754
1gb ddr400 RAM
80 GB SATA western digital hard drive
dvd drive
radeon ati 9550 AGP8X 256Mb tv in/out DVi video card

im not much of a hardware person, i was just wondering if there are any common issues that might result in no video being outputted.

the computer turns on, and i can hear it counting the RAM, but it doesnt show anything on the monitor.

Any suggestions would be greatly appreciated.


Thanks

Bobbie

first check the cable going to the monitor is in correctly and the monitor has power and etc. Make sure the processor and the ram and the video card are all seated properly in the MOBO. Disconnect the hard drive and the DVD for now.

Use all standard precautions when handling boards and working inside the computer, mostly make sure you are grounded: touch a bare metal part of the case with one of your hands at all times if you don't have a grounding strap to use.

if you have another graphic card you can try (pci or agp) try  it in place of the one you have now. If that gets a signal to the monitor then you probably have a bad video card. If you can try your AGP in another computer give that a try too.

yep monitor cable and power is all good.

No hard drive or dvd, i also placed the monitor cable into the onboard output, ive also taken out the video card and tried this to no avail.

ive bought two parts of each so i can make two identical pcs. and they both do the same thing. ill the graphics card in another pc tho.

cheers

Does your MOBO have a manual? Any instructions for adding a video card if there is onboard video?

I put the graphics card into a sempron 1200 and it all seems to work fine.

ive checked to see if the cpu is in properly and it is.
 the power led for the case isnt on, coz its an old case and seems to take three pins instead of two, but i dont think?

It has instructions

but it doesnt say much except how to put the card in, doesnt say about installing the card while the onboard is present, anyways i took out the graphics card, and used jsut the onboard video and it still had the same results

No video common mistakes

1) when the motherboard was fitted into the case too many brss mounting "standoff" posts were used or one or more have been put in the wrong place shorting the board to ground.

2) The builder has not used additional required power plugs, lots of newer motherboards have the additional P4 12v connector, some have a fixed molex on the mainboard, others even a floppy drive type connector, basically if any additional power connectors are fitted they are likely to require power.

3)The video card itself requires a power connector of some sorts (not sure about the Radeon 9550) but it may need a floppy type connector like some of the 9600's

4)cmos clear jumper is in the wrong position, simple 3pin header with 2pin jumper, has to be set to run position
Clear that cmos anyway! reset etc

5)New build? but insufficient power, builders using old power supplied not upto power their new hardware

6)Some addon card or periferal preventing boot

7)Any history? a blown power supply can damage hard drives and CDroms basically making them short to ground (when connected these damages devices will prevent boot)

8)A bit dramatic but a damaged CPU will often give the appearance of all things powering except video but socket 754 CPU's are pretty hardy and this is unlikely unless the system was powered up without a cooler fitted

9)Lastly and obviously, a damaged video card but you say it works on another PC

hi thanks for the reply

ill check the brass fittings, but that means i would have done it on two pcs, it is an older power boxx, its only 230V ? ill buy  anew one just in case, all other components are brand new so i dont think that there should be any problem there.

Yep the video card works fine on a p3 733 i have. ill check these things over tthe weekend. hopefully one of them should fix it! and ill get back to you

cheers for your help.

I believe the problem you are having is due to the AGP video card you have purchased and the AGP video card required by the motherboard.

Your ATI 9550 is a 3.3V AGP card while your motherboard specifically requires a 1.5V card.

While not 100% certain I think that the motherboard has been damaged by the use of too higher a voltage in the AGP slot.

A Radeon 9550 is a fairly new introduction and basically uses a lower clocked Radeon 9600 core.
The 9550 is a 4X/8X (1.5V/0.8V) card, not 3.3Volt which is the much older AGP 2X standard.
http://www.ati.com/products/radeon9550/specs.html

Also this motherboard is installed with an 8X AGP slot (0.8V) so I'm not sure where you are getting your information from?

The main features of Foxxonn WinFast 760GXK8MB are:

Socket 754.
Chipset: SiS 760GX (AGP 8x, ATA-133)
Super I/O: ITE IT8705F
Parallel IDE: Two ATA-133 ports.
Serial IDE: Two SATA-150 ports.
USB: Eight USB 2.0 ports, four welded directly on the motherboard and four available thru an I/O bracket.
FireWire (IEEE 1394): None (it’s optional, however).
On-board Audio: Produced by the chipset together with the codec Realtek ALC655 (six channels, 16-bit resolution, 90 dB signal-to-noise ratio).
On board Video: Yes, produced by the chipset (Mirage 2 graphics engine).
On-board LAN: Yes, Fast Ethernet (100 Mbps) produced by the chipset together with the Realtek RTL8201BL chip.
Buzzer: Yes.
Power Supply: ATX12V.
Slots: 1 AGP 8x slot and 3 PCI slots.
Memory: 2 DDR-DIMM sockets (up to 2 GB up to DDR400/PC3200).
Number of CDs that come with this motherboard: 1 CD
Softwares that come with this motherboard: Norton Internet Security 2004.
Extra features: None.

ATI’s RADEON 9550 is down-clocked RADEON 9600 featuring 128MB of DDR SDRAM memory with 128-bit bus,Graphics cards based on the RADEON 9550 will work at 250MHz/400MHz speeds for chip/memory, 75MHz below core clock-speed provided by the RADEON 9600, All graphics cards based on the RADEON 9550 and RADEON 9600-series VPUs are based on processors code-named RV350 and RV360. From architectural stand-point these two chips are same and feature 4 pixel and 2 vertex pipelines, but the RV360 is made using more advanced 0.13 micron low-k fabrication technology.

ATI and its add-in card partners would offer 6 solutions based on the RV350/RV360 chips with different clock-speeds, but the same DirectX 9.0 capabilities:

RADEON 9600 XT – 500MHz visual processing unit, 128MB/256MB 600MHz memory with 128-bit bus;
RADEON 9600 PRO – 400MHz visual processing unit, 128MB/256MB 600MHz memory with 128-bit bus;
RADEON 9600 – 325MHz visual processing unit, 128MB 400MHz memory with 128-bit bus;
RADEON 9550 – 250MHz visual processing unit, 128MB 400MHz memory with 128-bit bus;
RADEON 9600 SE – 325MHz visual processing unit, 128MB 400MHz memory with 64-bit bus.
RADEON 9550 SE – 250MHz visual processing unit, 128MB 400MHz memory with 64-bit bus;

ok Thanks fellas

that all sounds like the hardware i got. Im not sure whats going on here.

i couldnt make it into the office today, but i will be in the office early tomorow morning and ill go through the list proposed by paparazi. If there is anything else that might pop up that might be an issue, it would be great to know.

Cheers for the help

I appreciate it.

I tried loosening the motherboard but no avail, my guess is that the power supply is not strong enough its a 230 V??

ill try borrowing a mates and then get back to yous.

Cheers For the help

@Bobbie - the Voltage is not the power behind the PSU... depending on where you live, ie. US and CAN (some parts of CAN use 240v) they use 115V (+ - 5v)as standard, where as in Europe they use 230v on the mainland and up to 240v in the UK... about OZ I would not know, but I presume also 230v...

having established that...

now we look at the WATTAGE, for the system you described you may need at least 350w the more the merrier...

NOW comes the hard question: Does your PSU have the extra 4 PIN power connector and did you have it hooked up?

Indeed it does! you are a saviour!

it seems it needed more power, works perfectly now.

Thanks Very much for your help

Glad to see you found the problem although I did point this out in my first thread 3 days ago but you obviously missed it lol.

@Bobbie - Glad you got it running... In case you need any further help, please do not hesitate to call back here...

btw. I think Paparazi deserves the Star...

@Paparazi - I missed it aswell... LOL... I guess you gave so much good information that it just overwhelmed... :)
