I also purchased Windows 7 and got it installed on the new HDD just last night. The main things I use my PC for is gaming, Windows Movie Maker, and Fraps. I almost exclusively play Dark Age of Camelot; for those of you who aren't familiar with the game it's 10yrs old debuting in 2001. So it's not exactly a strain on my system.
Now to my problem... I've been getting lock ups randomly while either playing DAoC or sometimes just sitting at desktop. My only option being to manually restart. I assumed it was a result of a failing HDD. CrystalDiskInfo showed the HDD as "Bad" and posters here had the same suspicions after I listed all the symptoms. This problem intensified within the last 6 months and eventually resulted in my computer no longer being able to boot and thus my purchase of a new HDD.
Unfortunately I've had my new HDD and OS less than 72 hours and I've already had 2 lockups; one in game and the other just idle on the desktop. I'm at a loss to what can be causing the problem. Is it time to upgrade the 5yr old Mobo and Processor or am I missing something???
Here's a list of all my hardware currently in the system.
