Hi all of you, how are you?

I have TOSHIBA 505L Laptop, it has ati radeon 5145 gpu, and i3 2.13 ghz processor.

For past 4 weeks,i am getting display problems which includes no/bland displays, and some insect like bright yellow and white lines across the whole display.

I have installed every version of the legacy and beta drivers drivers from AMD but to no avail. I went to a technician and he suggested that it is the lcd/led's problem and so i changed the led monitor, but then again to no avail. The problem is getting sucked.;. Now whenever i startup the windows 7 64 bit, a BSD pops out every time. sometimes its written a TDR/TDA problem, and other times i don't know what is displayed...

Is my GPU is out of order??? or my CPU?? i think my GPU/CPU are overheating and i also noted through GPU-Z that in standby/stable condition my GPU clocks are getting high at no load at all. May that be due to clocking problem i.e., irregular and overclocked GPU??? OR may it be the AMD driver overclocking the GPU.???

So what do you think guys? any one having this problem and getting through solving it??
Give good expert solutions only, and no Guesses...plz plz plz

thanks & best regards,

eng. aamie.

first, to see if it's a windows/driver problem, or hardware, either bootup a linux CD, or your windows install CD and see if you get the problem. If so, has nothing to do with Windows/drivers and it's a GPU problem.

Now before I would have went out and bought a screen, I would tried the above, and if had the same problem as in Wndows, then I would tried an external monitor. If it did the same thing, it's GPU, if external was fine, then it's the LCD screen.

If it's the GPU, it's either overheating, dying, or needs a reflow.

Hi,

BTW i have tested it both by booting in Windows installation disc, and every other known boot disk available. and also tested id on external monitors as well. i did have some clue that it is a GPU problem but i thought i should also double check by replacing the screen but to no avail.

So it might be a GPU prob.. what is reflow? I also got some china made cheap ( a $1) thermal paste and by self applied it, but GPU temps didn't come down, they remain at about 55-60 C at no load, and also obviously it doesn't solve the problem.

So tell me how to correct the GPU, can i replace the GPU with a new one on the LT mboard.
or should i send it to the TOSHIBA CSR. will they correct it? what is the procedure for sending it to TOSHIBA mechanics. I bought it in a gcc country Oman...

thx
