can anyone help me with my computer

you could try something else...what OS are you sueing?

if it's XP...you could try going into task manager ( ALT + CTRL + DEL) and ending all the programs from your username except for explorer.exe and tskmgr.exe close everything else...then try opening a program that usually doesnt work...see if anythig happens...if it doesnt help then just reformat...
