Massive slowdown after 7800 GS install

bjdj82 · May 23, 2006, 12:42 AM

ARGH!

I just installed a GAINWARD BLISS 7800 GS 512 MB in my 3.06 GHZ Celeron with 1 GB worth of RAM.

Seems like everything is slow now. Boot time is slow (3 minutes), application loading time is slow, games are running incredibly slow...

I ran a defragmenter, a CCleaner, a registry cleaner and generally spring-cleaned my hard-drive. No result

Could this be a question of power-supply?

Nothing seems to work. What kind of info do you guys need so that you can help me solve my problem?

What kind of power supply do you have? But, I don't think that that's causing your problems...
Which driver set do you have on your system?

bjdj82 · May 23, 2006, 02:06 AM

a 250 w genereic - I think - without opening the cabinet.

The driver is an Nforce 8.3.4.0

Okay, well, that PSU is just not enough. Period. You need at least a 450W if not 500W PSU to run your card. End of story.
And do you mean ForceWare and not nForce?
Did you also make sure to use DriverCleaner Pro when you uninstalled all of your old graphics drivers?

bjdj82 · May 23, 2006, 11:23 AM

Yup, installed Forceware (sorry 'bout the nForce thing) and used drivercleaner.

But could the lack of power cause such a massive system slowdown. Everything starts up normally - it just takes ages. I mean, sometimes my mouse "lags" on the desktop when I only have one program running like Mozilla.

So is the lack of a proper PSU what's causing this?

did u use driver cleaner to clean out the old stuff after u uninstall the old driver?. and ur psu not gonna cut it. so i recommend buying a new one. maybe tahts causing ur problem. i recommend u do both and tell us of ur results. btw 400 to 500w brand name psu will do. there not all that expensive

I suppose your PSU could potentially cause that problem since your video card may be starving other components for power. Try a different PSU out and I bet you'll see some differences.

That card requires a power supply with a strong 12V rail.
A power supply with around 25-30A on the 12V rail would have no problems handling it, but a 250W PSU probably has a feeble, 12-13A 12V rail.

The bottom line: get a decent PSU. Avoid generic, no-name ones, you can get a reliable 400-500W (Antec, Enermax, Chieftec, Seasonic, etc.) power supply for 60-80$.
It's not worth risking an expensive system's life with an el cheapo 20-30$ PSU.

A few good examples:

I'm getting a new PSU like you guys suggested. One with 420 w. Not a no-name product...

But what I would like to know - what causes a massive system slow down? If not the PSU (here's assuming that a small PSU would cause my system to shut down if it was overloaded), not the registry, not a fragmented harddrive, not lack of disc space, not a lot of programs running in the background what then? Any suggestions?

bjdj82 · May 25, 2006, 07:06 PM

Is it normal that you cpu (normally idles at 87-95 with a virus-program running) and then spends all of it's processing power on a single, not-so-ressource-demanding, program like (just an example) microsoft word?

fobis · May 25, 2006, 11:12 PM

No, it's not, I don't think.
