8800GT not working with my mobo

[mc6701]

Hi All,

I am new to all this stuff so please go easy on me if i ask any 'stupid' questions.

It arrived my Gigabyte 8800GT after 3 weeks of waiting, but when i put it in no picture.

The card is replacing a Ati Radeon X1600.

My PC is a PackardBell Imedia 2770 (yeah sorry) intel core 2 duo (E6400 2.13ghz) spec here running Vista and i have done all the lastest update and updated the Bios for the motherboard which is a MSI (ms 7301) cuba board which does have a PCI-E slot for the graphics card. The card fits in all ok.
I have even bought a new PSU (Thermaltake 470w) with a dedicated power out put for a graphics card. Also tried using the cable supplied (2 molex to single pci-e).

Normal when i turn on my PC the fans fire up and it 'beeps' once and starts to load.

With the new card in the fans all fire up but it 'beeps' 3 times quickly and starts to load but the monitor said 'no signal' i also have it connected to my pioneer plasma and no picture on there ether???


So is the card DOA or is there anything else wrong???


Thanks in advance

Mark

Welcome to the forums
Could be a power supply issue
OUTPUT

Max. Load 22A--32A 14A 15A 0.3A 2A

Min. Load 0.5A 0.5A 1.0A 1.0A 0.0A 0.0A

Load Reg. 5% 5% 5% 5% 10% 5%

Ripple 50mV 50mV 100mV 100mV 150mV 50mV

the psu only has 14a and 15a on the 12v rails that may not be enough for a gt. I could be wrong though but someone on here should know?

Is it possible to try the card in another computer?

Thanks for the quick response,

This forum seems to have loads of info and some very Knowledgeable/helpful posters.

Anyway after a bit more research it seems my mobo is a bit crap and won't work with any mid to high end graphics cards, it seems Packard Bell only want you to use there systems stock and are really for the ' i know how to turn it on ' type user.

So have posted my story here. Any further advise would be great.

Do you really think the psu is not up to the job?? and before you read my story could you recomend a micro atx board that a 8800GT will work with so i can salvage my current set up.

Again thanks

still think it could be psu related (or at least it could be part of the problem). Everything i can find says 8800gt requires between 24a and 28a on the 12v rail, yours has 15a.

I will read the other thread bud and if i have any more ideas will post there.
Best of luck getting it up and running.

motherboard proberly doesnt support it or not enough juice to pci-e slot my mates medion pc with via 880 chipset did this last week with his asus 8800gt and he ended up getting a new mobo as i found out medion would not issue new bioses because it worked fine with the supplied card (7650gs) when pc was bought sounds very similar to what packard bell are doing,stinks abit tbh but thats what u get when u buy pre made mainstream pcs and why lots of us build our own.
edit : his board was the ms 7318 with the via 890 chipset not 880 so looks like exactly same problem

Thanks Will take back psu tomorrow and get a bigger one and give that a go.

What size do you think i need???

 

[Cyber-Mav]

even a corsair 450w will be more than enough for that setup your running. and those corsair 450w psus have 30a+ on the 12v rail and cost around 40 quid.

Got another psu today - a corsair one as recommended, but still now joy.

Have RMA'ed the card now - see what that comes back with. Hopefully a new one.
