hello: i have a toshiba satelite pro 4270 laptop, and am having a few problems with the ram. i bought it off ebay and the ram was listed as 192mb. when i recived the laptop, it only showed up as 64mb. when i went on the laptop the next day, the ram was shown as 192mb, shortly afterwerd i got a bsod, then a "stack dump" error or something of the sort. The day after i decided to install xp, as the ram had shown up as 192mb (which is enough to run xp). I installed xp and it ran very laggy and slow, and when i went to "system" the ram showed up as 64mb. can any one post a link to a recent SIS Savage I/X driver, because the graphical performance, and the clearness in which xp is displayed is attrocious! Can anyone give me an answer as to why this is happening, could it be a ram problem or motherboard problem?
