LAPTOP Video RAM Sometimes Changes??

[jcX4ever]

Hi

Im using A presario 2700 laptop

It has a Mobility Radeon (LY) with installed 32 Mb Memory chip.. So it has 32Mb Memory, but sometimes when I check the Video Adapter Information It says it has only 16Mb of memory.. When this happens, There are vertical lines when booting but they disappears as soon as windows is loaded, and when watching DVD (using WinDVD or WMP) vertical lines appears only in that window. But sometimes it detects it has 32Mb and everything goes fine and excellent-- no vertical lines at all..

Its a hardware problem? am I right? because this also happens when booting Knoppix on CD.. Thats why I know its not software related problem.. Maybe someone could help me here, I check the BIOS but there's nothing to be adjusted in there..

I just wonder why this happens.. is there something lose in my system??

tnx..

sounds fishy enough, check your laptop's bios utility for any setting you suspect to be causing the discrepency. how are things on the performance/stability front when it comes to the card showing different amounts of memory?

Overall my system is stable whether my video card works as 16mb or 32mb.. their only difference is in 16mb there are vertical lines when booting but when windows XP is initiated/started everything goes fine except watching DVD, vertical lines will only appear on the DVD window not on my desktop background or anywhere..

sometimes tilting in different angles (moving the laptop in different positions) when watching DVD and there are vertical line, pictures goes fine and excellent, maybe there are internal parts that is loose.. Is this posible..??

Regarding its BIOS, this laptop has a very simple bios not just like my desktop that has all power adjustment or whatsoever..

Tnx!
