Radeon HD 3470 artifacts in boot up, works stable in Safe Mode

[Szaryswierk]

I have quite old Toshiba Satellite A300 with ATI Radeon HD 3470.
4GB Ram, Windows 7 Pro

I have a problem with graphic card (I think?) It is artifacting, red lines showing up upon boot up.
It started few monts ago, by freezing computer.
At the moment I can only run computer in safe mode, and it works stable.
I've tried running Ubuntu and it can load, but freezes after minute or so.

I thought about flashing/updating BIOS, but can't do backup in safe mode with GPUZ.
Is it good idea?

I'm wondering if it is GPU problem, or motherboard?
Ram appears to be OK.
Any idea, what else I could do to diagnoze and try to repair it?

Thank You!

Seems to be VRAM related. Bad memory chips and/or solder.

Is there something I can do with it, reballing? Or replacement of Graphic card?

Easiest is replacing the card.

Hardest is letting zetabit.lab or actually hardcore overclocking troubleshoot and repair the card, they are on youtube

Id upgrade to a modern laptop

Which gpu would be copatibile, is PCI-E DDR2 only criteria of compatibility? Phisical dimension, or card size.is.a.standard?

Guess its a MXM Card
while other MXM Cards will fit>>> getting it to work can be a ***** as often the laptop bios is white listed only to allow certain Cards.
You would need to Research the web to find more info.

good place to start
are manafacture's forums

Mobility Radeon HD 3650 and AMD ATI Mobility Radeon HD 3670 was fitted in some later spec versions

Thank You for help and comments. Problem was not GPU ( I've almost bought) but processor ( one of its cores)
I experimentally turn on laptop with only one core running, and everything works good.
No I need to find Intel Core Duo 2 T5800 2Ghz, or something better?

I know you fixed the issue but if you are using a card that old and haven't replaced thermal paste I guarantee it will be causing issues. It all drys up after about 5 years in my experience (except arctic silver).

Also was going to suggest under-clocking the card *due to thermal issues mentioned ^^ good to hear working again (odd CPU core would result in bad Display).

 

[Szaryswierk]

Yes, I will repace thermal paste in CPU and GPU.

Can You give me advice about CPU. Should I buy the same: Intel Core DUO T5800 2Ghz, or Can I upgrade a processor to better one?
Can You give me examples of processor better than mine I can use?

You would need a Socket P CPU 800FSB...

Supposedly a T9300 will work by TDB as well...
