problem with ati radeon9800?

[outro]

Hi all...

İ have a problem with my comp. but dunno what the problem is.
I have a note on my lcd tv ( hyundai l19t ) video mode not supported
and sometimes the monitor turns its self off.. and sometimes its frozens. i cant move the mouse or my keybord does not work.

i have tried to change the resolution and refresh rate ( 60 mhz to 75 mhz ) it did not worked.

i have tried to re-install the windoxs xp, download the latest version of video card driver and latest driver of my lcd tv.
but they didnt help either...

i have tried to start it safe mode but sometimes the same things happen in safe mode.

i just think that some of the settings in bios might be changed.however while i was in bios checking the settings it gets frozen.... and i have to push restart button but it didnt worked too. i turnd off the comp and wait about 5 min. after that the comp seems to load the windows but in a few minutes samething happens again.......

is the problem my video card or the lcd tv or software...

can someone help pls....

Hardware wise the 9800 has always been a pretty reliable bit of kit for me. The only trouble I had with mine was the cooling solution recently crapping out, fan was still spinning up but a little noisily. I would get corruption and lockups in 3D and dvd playing and other weirdness.

Might be worth ruling out heat as a problem, just take the case panel off and point an 80mm fan or whatever you have laying around at it and see if it improves.
