ok, heres my problem, at first games would crash often, then i couldnt even install games, saying a cabnit file is corrupt, or there is a problem with my networking. I took my comp into a shop, they said i needed a new operating system, so i bought windows vista premium 64bit installed it. First I installed wow which worked, then I had to download the patches, after downloading they wouldnt install, saying the download was corrupt, or there were too many errors in wow to reinstall it. I did a chkdsk in the command propmt, says theres nothing wrong with my hard drive, I have dual channel memory, so I bought 2 new sticks of 1g ram to replace them thinking that could be the problem. When i put the new ram in started the comp. it wouldnt boot, just a black screen and gave me the boot code of 1 long beep followed by 2 short over and over. I think that means a bad video card, i took it out, put it back in, same thing, so i used one from a different computer, same thing. does any one know what could be wrong with my comp? its like 3 months old.
