Why does my computer show a Blue Screen for only a half a second, then doesn't start up?

Well, when I try to start my computer which is a Windows XP Home Edition, There is a blue screen that has all these assorted letters and numbers on it. It is only there for not even a second. Then startup repeats over and over again. It never goes to the login page. I have to make it go onto Safe Mode with Network. I don't have my computer Administrative Password. I restored my computer.--The first time I restored it worked and I was on the normal mode.. The second time it didn't. I need help I can't play any of my games. I have defragmented my computer, I have ran anti-virus software. Nothing is working. PLEASE HELP ME!!!

ONce you get in safe mode delete the graphics card. Then start the system back up, if the system can go into windows normal then reload the graphics card drivers. If after you reload the drivers for the graphics card then you might be in a new world of having to either find older drivers for the card or just getting a new graphics card.

Udate your antivirus and scan your coputer in safe mode. After you remove virus, I recommend you use firefox browser. It is safer than IE. It can prevent viruses such as worm,trojan and etc. The newest official edition of firefox can be downloaded from http://www.mollzia.com
