My mom has a Dell Dimension 2350, It has the 2 ghz Celeron, My sister decided she wanted a cd burner. So she had one put in by a local shop. The next day the pc crashed and she could not do a lot of stuff like use her modem etc...She only has 128 MB of RAM, with Win XP home. I figure it is way under rammed

for lack of a better term. I went to dell's website it says the ram it uses is pc2100 DDR could this be true with a 2 gig celeron? Any input would ber appreciated.
BTW I am like 1500 miles away from her so I have no way of looking at the ram it has
Thx,
