I have been having a long term problem trying to install games and large programs on my computer, when its a game it stats the game is currpt (CRC) but it cant be, becase i have had the games/program installed before and some are org games / programs, i have tryed a number to things to try and fix it, many new operating system.... didnt work, i have looked all over this site for this problem and a fix but there are to many to read them all, Is there a free answer to my problem? If there is please let me know

I have tested the ram. i did a full diagnostic a few hours ago, all is running normal, but some parts have low power could i have a bad power pack?

I get the error with any program that is more than 400MBs

Operating System: Windows XP Corp SP1 AMD XP 2000 2x 256MB DDR 333 (name unknown) GVA7 Motherboard (on board sound) ATI 9800 Pro 250MB problem stats every time (Error CRC currpt file "Drive and Files location") its not the stated files installed its a computer hardwear/softwear problm,
