A bit confused here guys.

I've replaced the graphics in my girlfriends pc went from a x600 to a 4670, now the card went in ok and windows booted up, then i installed the latest ati drivers and window2s rebooted. Nothing unusual so far.

Then after a reboot, the pc slowed down. I mean really started crawling... took ages to start up.

Would this be a symptom of a psu not being powerful enough to run the new gfx card.

Any other things i can, should, check.

TIA

Yeah sounds about right, a 500w would probably do you fine for that gpu, maybe even 400w depending on your cpu and other parts. [might be pushing it a little though]

Good luck!
 
well i brought a 450w psu and its still the same.

The processor seems to run at 50% on one (pentium4) and the actual pc proccesses are doing otihing at all.

The only thing i have is the mobo is a pci+e 1 the card 2.0, i didnt think this would be an issue for th eprocessor though.
 
300w would run that easily assuming it's half decent. PCIe 1 wont makea difference either.

Whats the 12v ampage on either PSU?

Tried removing and reinstalling drivers?

Click to expand...
what brand is the psu?

its not just about watts. u need enough amps on the +12v line too.
 
you say it works fine with your old card bk in the system maybe its a heat issue , i had an old 1900 xt card and the fan stopped working on it and the temps got way to high and the pc kept slowly grinding to a halt and crashing ,check the temps of you gfx card see how high they run idle and under load ( use gpu-z it will monitor your gfx card temps while you stress the card in a game or bench mark) you can get gpu-z here http://www.techpowerup.com/downloads/SysInfo/GPU-Z/
 
uninstall drivers completely, then download and install the very latest one from ati site. Also how hot is it running?
 
the card itself does crank out heat, the fan never slows down, i have actually taken the card out and running back on the oilod one, after lunch i'll have another dick around, get you some system stats. What i do find odd is the cpu, its a dual core, one core runs at 50% constant with nothing actually running.
 
clean out of ideas now. Formatte dthe machine witht he new card in no problems. As soon as i install any drivers it goes nuts again and the pc grinds to an almost stop.

Get tthis though, its not just the gfx drivers. When i started over and installed the nic drivers first..... same thing.


Think i'll just give up lol... anyone wanna buy a hd4670 LOL
 
That is rather bizarre, you'd expect crashing if the PSU was not up to scratch rather than just running slowly hmm.

Have you access to a friends machine so that you can try some organ trading?
