Infinite loop fix!

Hello!

The ati2dvag infinite loop error always occur everytime I play Sims 2 Seasons.. I have ATI Radeon x1550 (it's a PCI Xpress card) and Catalyst 7.4.. I tried the fix but I couldn't seem to find the CPU to AGP Controller in System Devices.. I read the thread and I wasn't able to find any answers for PCI cards.. Please help..

So Excited!!!

This worked perfectly for me from what I could tell. Just went through the process & booted up w/o blue screen like a charm! I was so excited I had to post this even though I may never use this login again. THANKS VERY MUCH!!!

P.S. This was an eBay gamble is why I'm so excited

infinityloop loop fix.

hello,

My HP NX7000 works perfect again, thanks to you!!


cyberlub.

well i have a similar problem every time i play a game after a while my screen justs goes black like its in stand by then im froce to manully shut down my computer do you think that this fix would help me

Man, u r awesome. Sony VAIO users and V game players, look at here

first, great thanks to cobrakaun. At least, so far, my laptop back to normal.

I have a Sony VAIO crap S260p laptop (never buy sony again). It began show blue screen from this morning and crushed many times today by the ati2dvag error. By the end, it can only last less than 3 min after powered up.

I followed cobrakaun's steps and finished in <3 min (not easy, try a few times). Now it back to normal (at least for half hour).

What I figured out is, a few days before, I remembered I changed some setup for my video card in some game setting!!!

If you have the same problem, see if you also did some changes when you just install a video game recently. I don't know how to change your setup back, every game differs from others. You need figure out by yourself.

Probably what happen is that after the setup first changed, your video card conneted to cpu in a wrong way (at least not prefect way for your computer). The system can last sometime in this way, but some hardware (capacities) may be burned. Then, this way can not work anymore. This is just something I guess, sorry, my major is not in hardware.

Good luck, folks.

This solution didn't work for me, at all!
My specs:

Gigabyte main/motherboard - can't remember the version.
1GB DDR2 RAM
250GB Seagate HDD
Club 3D ATi Radeon HD 2400 Pro AGP

Can it be, because of my graphics card is AGP?

ATI2dvag.dll infinite loop fix needed!!

I have a Sony VAIO VGN S260 and has been good pc till few weeks. Now it is acting wierd and have problem booting up. Plus just shuts down after 30 mins.

I tried to follow CobraKaun 's fix but i couldnot find CPU to AGP controller.

Please guide me. I cannot affort a new pc at this time.

thanks

Hello! New member, and I hope I have something to contribute on day one...lol

I recently purchased a Dell Inspiron 9100 (XPS style) laptop that has the 128Mb. ATI Radeon Mobility 9700 graphics card in it. The first time I booted it up, I got the ATI infinite loop BSOD. It would boot up to the point where the login screen was supposed to load, and it would pause there for about 20 seconds and cough up the BSOD. So I held the power button down to shut down and then restarted the laptop. It went right in the second time.

I changed drivers, no good. I tried Omega drivers, no good. I reinstalled XP Pro, no good. One day I tried to start it up off of the battery instead of the power supply, and I got one infinite loop BSOD after another. I could not load XP while running on battery. Later that day, the laptop coughed up the infinite loop BSOD while just sitting there idling in XP.

I researched this on the net, and I am surprised that I have never encountered this problem before. I build custom computers for a living (own business), and I use ATI exclusively unless a customer specifies otherwise. Out of hundreds of systems I have built, none have had this problem. So that caught my eye right away. Why have I been the exception? Also, I know Dell never would have sold this laptop if it ran like this from day one. These clues led me to find and fix the problem with my laptop, and now it runs perfectly. On battery and on AC power.

In all of my reading, one thing that kept coming to mind was heat. The Dell 9100 laptop I have has a 3.2 GHz Prescott processor and Intel chipset package, on top of the Radeon. It is a small furnace when gaming. When I build custom gaming PC's, I use aftermarket GPU coolers and thermal paste (AS Ceramique on the GPU and AS Thermal Adhesive on RAM sinks) and large, well ventilated cases that are equipped with way more power supply than is necessary. So my systems run cooler because they are designed to do so.

I installed a temp monitoring system on my 9100 laptop, and I recorded the temps at idle and full gaming loads. The cpu was hitting in the mid 150's (F) under load and idling at 129. The chipset was hitting the mid 150's under load, and idling at 136. The GPU was hitting low 160's under load and idling at 134. All of these temps are high, at idle and load. I pulled the three fans out of the laptop, cleaned them (they were pretty clean to begin with) and tested again. The temps barely dropped (1-2 degrees).

So I pulled the laptop apart, pulled the thermal pads that Dell used and checked the heatsinks for contact. The cpu and northbridge heatsinks sat right on the chips, so I reassembled them with AS Ceramique thermal paste. I pulled the RAM sink and heatsink from the ATI 9700, and removed the thermal pads from them. I noticed that one of the two RAM thermal pads were discolored. Interesting. After pulling the GPU thermal pad, I placed the heatsink back on the GPU to check it for clearance.

I found the problem! The heatsink on the 9100 is almost .050 of an inch off of the GPU chip. The thermal pad showed that the GPU and the heatsink were not in close contact. I laughed my rear off when I saw the gap. How in the heck Dell thought this was ok is beyond me.

The way the heatsink mounts, the only way to bring it closer to the GPU is to shave the four mounting legs down (shorter), so the heatsink is closer to the GPU. My heatsink legs were .247 inch long, and I cut them down to just under .200 inch. The back brace the heatsink legs screw to also has to be cut down a like amount so it clamps the heatsink in place properly.

I carefully dry assembled the RAM and GPU heatsinks, and bent the tabs on the RAM sinks so they would line up with square with the RAM chips and to take up the space that the thinner adhesive strips left. The RAM sink is very thin and you can bend the legs (carefully!) on it with a pair of needlenose pliers. Once everything lined up, I replaced the thermal pads that were on the RAM sinks with thin thermal adhesive strips for computer memory heatsinks. I put a dab of AS Ceramique on the GPU and then reassembled the video card.

I put it back together, held my breath and fired the laptop up. It went into XP without hesitating. I shut it down and pulled the power and then started it up on the battery. It started and went in to XP fine. I have been using it for a week now, and no more problems. The cpu temp is 134 under load and 112 at idle, the GPU is 138 under load and 114 at idle, and the Northbridge chip is 145 under load and 115 at idle. This is a huge improvement over the original readings.

High end graphics cards are heat and power sensitive. Heat is resistance, and resistance means less power. That is why overclockers commonly mess with voltages on their system to stabilize them. Well, the inverse is true too. If you have just enough power to get the job done with little headroom left, overheating will cause problems where none existed before.

I hope this helps some people out. I do not think that this is the sole answer to the problem, but I bet it is a major factor. Another point is that switching to the PCI to PCI bridge does not push the video card as hard and that explains why it helps some people out. Temperatures are reduced with less drive, and it only masks the real problem.

Heatsink pads and compounds will eventually dry out. Service your computers, and do not assume that Dell (or any other manufacturer) did everything right the first time. That GPU to heatsink gap on my laptop was a clear mistake, and Dell expected the crappy foam thermal pad to do the job. It failed.

Thank You!

I just wanted to send a note of THANKS! I had started troubleshooting this problem and started the normal ways - updating video card drivers in Safe Mode, etc. Luckily your post came up first on Google and I tried it and Voila! pc problem fixed. This saved all kinds of time - so I just wanted to drop off a note of THANKS.

Hello there, can you please look at these pictures and what here is an CPU to AGP Controller? I have been experiencing the infinite loop problem for months, becuse of it i could not play and advance game or anything. So i am just hoping that you can help me to find my problem.

Wich one of these is the CPU to AGP Controller?









I do not know what AGP TO CPU Controler means (I know AGP Stands for Accelerated Graphics Port and CPU for Central processing unit, but i do not know the names of either of these in my sistem, so please tell me what they are XD, and if i don't have them can you please tell me how to get it?)

Thanks a lot!!!

mine was VAIO VGN-S360P
ati2dvag/ ERROR / BLUE SCREEN

PCI TO PCI OPTION WORKS GREAT!!!
THANK YOU.

YEAAAAA! ATI2DVAG fixed indeed!

it worked! this finally fixed the infinite loop problem! I love you sir, really, really I do!!

Thanks again, your post was probably the last I would have ever read on this topic, after 10 hours of non-stop frantik searching on google, you saved my day!

Again, a million thanks, hope google picks up on this thread since it's by far the best solution to fixing that infinite loop ati2dvag bug for the x1650

God Bless you for this!

I've been at this for 2 days straight. Promised my 7-year old nephew that I could install a video card so he could play his Roller Coaster Tycoon 3 game. ATI Radeon 9250. Was even the card suggested by the game maker. I think he was afraid Auntie had lost her touch. You've given me the chance to be hero again. I've forwarded your fix to microsoft so you can save others from hours of frustration. A thousand thanks.

Thank's dude

Nah, it still doesn't work for me. I'm still getting infinite loops...

My Specs:
Intel Dual Core 2.0 Ghz
ASUS P5VD2-VM SE Motherboard
1 gb DDR2 Kingston RAM
ATI Radeon X1550 512 mb (with latest driver version)

hope this helps someone

i had the infinate loop displayed on the blue screen of death

the only was to get into windows was via safe mode in vga

removed all drivers and started it up again, reloaded drivers... no fix

after turning it off a few times it just would no longer load and restarted prior getting into bios and failed to turn on monitor.

obviously i freaked out at this stage.

tried running one car instead of 2

no fix

swapped cards etc

no fix

tried starting with no video cards at all (no onboard)

still no fix so it couldn't be the cards - possibly motherboard?

i tried whilst still able to get into windows all the above fixes with no luck

spoke to my it bloke at work, tried a few things and got it working

problem was my ram had given up the ghost. i was running 4 sticks of 1gb kingston ram

to find this out

i removed slots 2 and 4

no fix

swaped the removed ram with 1 and 3 and started up fine

reloaded the ati drivers and works!

basically the ram was shorting out creating wierd stuff to happen then gave up completely which wouldn't allow a boot

bit slower now i'm on half my ram but happy the cards are fine.

thanks to all those who posted previously.

assisted me to find the fix - just posting this as an alternative possible solution... worked for me

system
4gb ram
3ghz intel core duo
2x ati radeon pci 512 vid cards in cross fire
win xp

looking for proper gaming ram now with heat sinks

may have been the cause of the failed ram although i have 5 fans in the system in total!

Cheers guys for the previous posts and i hope someone can make some use of this

ati2dvag frustration

Ive tried the fix but nowhere under system devices does it say agp to cpu controller or even remotely close please help im gonna throw that card on the road very shortly.....

I CANT FIND "right-mouse on CPU to AGP Controller (or whatever your controller is called, mine was SiS AGP)" PLEASE HELP!

Meeee toooooo!!!!!!!!!!! Argh!!!
