Hey guys, lately my computer has been getting really laggy after it boots up. I try not to restart it for this reason. When i turn it off, or reset it, it will boot up, sounding like its working REAL hard, then when it signs me back on, it will take like 10 minutes for everything to load. Also when i first sign on, it will say my computer is at risk, but then it will be fine, and when msn is loading, it will sign me on, then ill lose my internet connection for a min. But after i give my computer about 10 mins or more to settle down, it will work a bit better, but it still laggs real bad for a long time. I have read up on how to optimize my computer, and i did a Disk Check, and Disk Cleanup, but that has done nothing. I was going to defrag my comp, but it wants to take files that i use away. The computer is have, isnt good, but its just been acting up in the last little bit. Im thinking i just need to upgrade the ram and hard drive because right now i only got a 160 gig hard drive and 448 mb or ram. Any ideas on why this is happening, and what i can do to fix it?
