In other words, my laptop's smurfed.

If that's hard to read...
Code:
Memory address line failure at 00204040, read DFDF4FDF expecting DFDFDFDF
To resolve this issue, try to reseat the memory.
Decreasing available memory
The amount of system memory has changed.
If you did not change your memory...
To resolve this issue, try to reseat the memory.
What do I do? I've already tried reseating the memory, and nothing changed.
I really need a fix to this ASAP-- the 12-page report I typed last night that's due tomorrow is on my laptop!
Please help me, and fast! ;;
EDIT: After spending an hour with a tech support guy, it turns out that one of my memory sticks are fried. The other is fine, but I have to run on a pathetic 2GB of RAM until I get some replacements mailed to me. Please disregard this thread.
