Computer stutter after installing a new graphics card

xX-Gh-Xx · Oct 29, 2015

Good day people, i got this really annoying problem (not for the first time).

I've installed a new graphics card (Nvidia Geforce GT 440) almost 3 months ago but from the beginning it had weird stuttering problems in games. I was running games on max settings at 60+ fps (Terraria, Dark souls II), but it had frequent stutters and it was quite annoying.

Month ago, games started to stutter occasionally but not the computer overally, just the games.
It got fixed by itself later. Now i got that problem again, but now even desktop stutters and it's really unpleasant. The programs are stuttering and hitching too..

I've installed windows 7 64 bit, but it didn't helped.. by the way, that problem started after restarting computer because of glitched desktop bar. After that restart, everything was lagging and unresponsive, i had to restart again.

Specs:
OS: Windows 7 Professional 64 bit
Processor: Intel Core 2 Duo E7300 2.66 GHz
RAM: 4 Gb DDR3
GPU: Nvidia Geforce GT 440
PSU: around 360 (i think)
Motherboard: ESPRIMO P3510

Do somebody know what could be the problem, please?

You may have gotten a lemon GPU or you might not have enough power, that wattage is very low.

Its possibly that PSU, it maybe able to do 300w

That actually may be the problem. I'll try to get some PSU with higher wattage. And thanks for the answers

, i really appreciate it.

By the way, by "lemon Graphic card" you mean what exactly ?

xX-Gh-Xx · Oct 30, 2015

I've tried 400W PSU, but the computer still stutters.. Does it need even more?

So this stutter happened, then you installed a clean version of Windows 7, installed drivers, and it continued? Maybe a failing hard drive.

Meh.. probably not. My computer's HDD is working as it should, and it isn't even that old.

xX-Gh-Xx :

Did you do a HDD Test in the BIOS?

xX-Gh-Xx · Oct 30, 2015

TheDankMemer :

There is no option to do that.. But i've ran HDD error check in the disk properties and it haven't found nothing.

I'll describe that problem a bit more, so..

Both my desktop and my games stutter..
In desktop:
-When i move a windows to edge, it heavily stutters sometimes while it's opening that glass like effect
-When moving windows it stutters sometimes
-When drawing: Micro stutter can appear
-When opening something or clicking on something, it's unresponsive sometimes

In games
- It's stuttering almost everytime
- Lags spikes are showing up very often
- Frame skipping very often too

Do you have up to date drivers? Are your fps good while your are playing? Sounds like a driver issue to me.

xX-Gh-Xx · Nov 1, 2015

blakem :

Yes, my drivers are up to date. And yeah, my fps is actually good:
- Path of Exile (Max Settings): 80 FPS
- Terraria (Max Settings): 60 FPS
But it's having that stutter as i said.

With that Hard drive as Hang-the-9 previously said.. it actually may be the truth..
I was running some programs, and every one of them showed me that one sector isn't stable
and one program showed me that data is damaged too.. so it actually may be the problem of
HDD.

A lemon graphics card is just one that might have been messed up in shipping or manufacturing and something is wrong with the physical aspect of the card. It can be hard to tell.

That_Person :

Oh okay, thanks! But i don't think it's a lemon graphics card, there weren't any other problems than a stutter... I guess it was HDD all along, i've checked it and one sector is unstable, and some data was damaged too, i guess i'll have to wait for a new one.. anyways one more thanks for the answer
