Hey all, I like to do some of the racing games like nfs underground and F1 racing but now my pc is locking up. Well I guess the frame freezes for about 30 to 45 seconds on then goes on like nothing happened, then about 25 to 50 seconds later it does it again, so for a say 2 minute race it takes me 5 minutes. any ideas. here is what's in my custom build pc that i did 2 years ago.

win xp, pen 4, gig SiS-645 mb, 120 gig hd, 1024 meg mem with 1 open slot left, cd writer, dvd writer, vid card is NVIDIA GeForce4 Ti 4600, and a veiwsonic monitor.

Also just when I am surfing the web, when I have IE open sometimes my screen goes form white to yellow and sometimes flickers yellow then white. sometimes when I tap the my pc case it will go back to white like it should be. Time for a new Video Card? What is a good cheap card. this one lasted less then 2 years, if that is the problem.

Thanks Larry
