graphic card problem.

[kryton]

just wondering if anybody could shed some light on this please.

this morning i fitted a second hard drive to my pc.
i started the pc up and got nothing, the CPU fan was spinning like hell.

i finaly found that if i take my graphics card out and use the onboard graphic socket the pc boots as normal and everything seems fine.

if i plug the card back in (sapphire HD 4870) the CPU fan goes nuts again and i cant see the card in device manager.

strange thing is where i fitted the new hard drive was nowhere near the GFX card so i cant see why it would harm it.

the only thing i can think of is an overload on the power supply? its only a 450 watt PSU but why would this make the CPU fan speed up when the card is inserted?.

any ideas?

thanks

yeah could be a few problems there

try

go to bios turn off onboard graphics
insert Saphire 4870
disable smartfan (make sure you have low temps first)
turn on pc

if it is temperature im not suprised because ati gpu's get hotter than nvidia's but shouldnt be causing the cpu fan to go crazy

power issues: youll might have to check the power requirements because the GFX cards need decent power supplies nowadays and all the connections in the case should be checked.

just a little info

Sapphire HD 4870 512 MB - Bjorn3D.com

Thanks for the reply mate.

well i know my PSU is a little under the minimum spec for the graphics card, the PSU is 450 watts and the recommended spec for the card is 500 watts.
but it was all working fine untill i added the second hard drive.
this is what got me thinking, maybe the load has somehow weakend the PSU?
i can boot with onboard graphics with the card in.
i cant see the HD 4870 in device manager and also the CPU fan speed must be at its highiest rpm

soon as i take the card out the pc runs fine.

ive been through the BIOS several times, the only thing that was odd was the date and time had changed, it was showing the 9th of feb...and the time was midnight.

the onboard and gfx usually dont work together you need gfx card or the onboard graphics
and how new is that card? if its new new then id get a replacement if it carries on.
the bios change might of been due to a reset

Got it right there.

Your trying to draw 5 amp of power from a 3 amp source.
The hard drive doesnt weaken the power supply it just draws current thats already scarce, leaving you without adequate power to fully boot.

Plus the well known fact that ATI are completely poo, yes the word poo most accurately describes the material between the ears of the driver software writers, your problems begin with installation regardless of the PSU feeling queezy with the runs. The next time is wen u change OS

Should have bought NVIDIA, better components better cooling and better drivers or i should say working drivers

good luck with catalys ...

Well @roo001... i use both ati and nvidia cards... I'm going to go out on a limb and bet you didn't bother to check and see which brand would work best with your mobo. Ati are owned by amd... and you can bet your last ? they are not going to go out of there way to let intel or nvidia products sit along side there own without a fight. As already stated i use both brands... but with a little research i have no probs with my rigs at all.
