It was running fine up until a few days ago when the colors went screwy. Everything would be pink. My son would repeatedly reboot until it worked. Manny many times he just used the reset button.
Then it slowed way down.
I replaced the video card and all is good with the graphics but the computer is still way slow.
CPU usage stays pegged at 100%. It takes 5-10 minutes to boot. I ran chkdsk in safe mode and it didn't report any problems.
I am running Spybot on it in safe mode but it's taking forever. It's been 12 hours now and it's about a third of the way through with no problems reported.
Norton antivirus is on the comp with scans run every night.
At this point I don't know if it's a software or hardware problem. Any help or advice would be greatly appreciated.
