Mom's run out of things to try to fix her computer at home

Our mom wants to ask for everyone's help with solving our problem. We've spoken with a few of our friends and they have tried to help us and we thank them so much. However we still cannot see any color in our boxes or see the background photo of the woods in our backyard while we are on our home computer. Any changes that our Mom makes on it show up on some other computers, (even our Dad's cheapy deepy MSNTV viewer on the TV in the living room.) We cannot even see the little bisquits load under friends photos to vote on them. Mom uses Windows XP S2 and we have tried both IE7 and FireFox browsers. Mom did have her security settings at med-high, then she lowered them to just medium and it didn't change anything. She put them back to a Med high custom setting. She has tried deleting the temporary cookies and then enabling them again. We keep getting an error  (yellow triangle) message saying that an item on the page did not load properly..Line 46 char 1 object expected code 0 .., and object on page line 62 not directed..I think.. whatever the heck all that means... we tried putting everything back to a windows default setting, everything still looks the same on our end. Mom has spent most of the weekend messing with the stupid thing and she's ready to chuck it out the window and buy a new one , Dad vetoed that idea ,too expensive!..well, for right now anyway....grrrr.. If any of you out there have any ideas on what she should try please let us know. And could you all bark at us and tell us what you see here too? Some of you did earlier and we want to make sure nothing else got messed up with her obsessing. Can you tell our Mom's not really much of a techie?  On her computer at work everyone's pages all look so beautiful and she can vote on your great photos and everything...but she's not really supposed to be surfing the net from there.. so she has to quickly browse only during her breaks.... jeeze it's stressing her out...and you know what that means.. we get stressed out too cause she doesn't give us our cheese snacks on time when she gets home...take pity on us cheese deprived doggies.. please help her become more MDS savy. Kes, Gracie and Pearl.
