No desktop progams

I don't know what I've done but when my computer boots, all is fine until I usually get my desktop. Now there are no available programs whatsoever. An error message comes up : The instuction at "0x7c901e76" referrenced memory at "0x00880000 ". The memory could not be "read ". Click OK to terminate program. I click OK and I go back to a blank desktop. I hit Ctl-Alt-Delete and it says that it has been disabled. If I try in safe mode I get a blank screen that just says safe mode in the corners. What have I done???

 

Does Task manager work in safe mode?

if so find > explorer.exe > end task, then go to
Start > Run > and type in "explorer.exe "

I dont know much about computers mate, im trying to help you as much as i can so dont make fun of me, hope this helps

 

Or when its starting up, rapidly tap [F8] then it will take you to an adavanced option selection, try going in debug mode, should restore to normal state so you can fix i think, not sure.

 

Unfortunately nothing works in safe mode. I tried debugging with no luck as well. Thanks for the suggestions however.

 

well i guess you need a windows xp CD to repair, im guessing you dont have it?

 

Just moved and cant find it as of yet... not sure if I do
