very strange 3d Problem.. help please!

[rocky45]

Hi everyone.I am new in this forum and I need help please.

I bought a new HP DV7 laptop a few months ago with a Nvidia Geforce G105M graphics card.

I have a strange problem , wich began a few weeks after I bought the laptop, with 3D games and 3d applications that run with DX9 only (I don't have this problem with DX10 applications).

The problem is when I start any game wich support DX9 only, I see glitches, flickers and every 3d object in the game flicker.

here is a video wich I have recorded using Fraps from my laptop when I started Section 8 prejudice (the game support dx9.0c only)

Also, when I run some games I can see only a black screen and hear the sound (games like dead island, men of war vietnam...)

As I mentioned below, DX10 games works very well, I played Resident evil 5 DX10 and red faction Armaggedon DX10 without any problem.

I have the latest driver installed (280.26 WHQL).

here is the laptop's specification:

Intel core I3 330 2.13GHZ x4

4GB RAM

Nvidia g105m mobile GPU 512MB VRAM

640GB hard drive disk

Windows 7 64bit Home Premium SP1 edition with latest drivers updated

Should I change the video card (if it can be changed of course) or what?

Any help will be greatly appreciated

This is defiantly a GPU issues. What are your temps temps when playing? If they are within reason say under 70c then your GPU is most likely fried. You could if you wanted to re-install drivers most likely wont help but it's worth a try.

What settings do you use when playing? It might be that you are running out of Vram if you have AA and other settings on very high.

Hi,

Don't think that's anything to do with vRam. It looks like a broken GPU to me, my guess being that the DX9 titles are maybe heating the card up more. In some cases, as a DX9 title might be "easier" to render (both GPU and CPU wise) the card can achieve very high frame rates, this causes the card to heat up more and might be what gives you such bad artifacting. A newer DX10 title might be more demanding, giving lower FPS and not work the card quite so hard. This might sound odd but I've seen this for myself. Indeed there have been bugs (most notably Starcraft 2) where one of the splash/menu screens had no FPS limit in place and REALLY stressed GPUs because of it, even though the scene rendered was "easy"...

I've seen artifacting like that myself and it's always been caused by a bad overclock for me OR when the card is dieing.

Either way, something really isn't right, I'd be inclined to be seeking an RMA of the laptop - or call out support if it's on-site. HP have been VERY good in my experience providing on-site support with a faulty laptop.

Cheers & best of luck.

Scoob.

My temps are 82c or above (sometimes 85c).

I've reinstalled drivers and tried lot of them, but the problem persists.

I play DX9 games with medium and low settings, but this doesn't help me...

I think this is right because I launch some games with 3D analyzer tool and I choose limit DX9 hardware caps option and it helps to fix some artifacts.Could I change the overclock options of DX9?

Do contact HP support, they've been brilliant with the laptop I bought the other half a while back. Her GPU failed totally (blank screen) and they replaced it on site. Her HDD also failed and that got replaced on site too. Ok, it's not so great that the laptop had two major issues like that, but they were resolved pretty much next day.

i have found that when running starcraft 2 on any of nvidia 285.XX drivers i get crashes and artifacts system freezes and just black screens with sound but not when i use the 275.33 driver i have 2 n460gtx hawk talon attack graphics cards

Nvidia Drivers and graphics cards have lot of problems and issues. I think ATI is much better!

have you tried running this in windowed mode?

helped me for example when running crysis 2 on a 5970.

certainly no permanent solution but you will be able to determine if your GPU is running properly or not.

always a pita those notebook gpu chipset because brands like HP do like to tamper with them in order to prevent the use of reference drivers.....
