vid problem on xpsm170 :(

hi all,

 

my m1710 is acting weird like this:

 

 

At first I thought it was some sort of virus but, after formatting reinstalling etc. I only get blackscreens, and even when I can Start Windows XP properly, it will only work for 2-3 minutes.

After that it reboots itselfs and eventually going black again ( @ login screen).

 

I ran a diagtest @ boot ( F12 during Dell Logo ) and it appears that my Video memory cannot be accessed:

 

Errorcode 5300:0119

Detected a failure while writing and reading video memory

Video mode : Dh (320x200x16)

Address a4a60h, expected to read 0h, but red FF000000h instead

 

what can I do to make it work properly again?
