Hi guys I am new to this forum, but thought somebody could help me out with this annoying problem I recently had with my computer. Much appreciated. To start off, here’s my spec, AMD Phenom II x3 710 GIGABYTE GA-MA770T-UD3P G-Skill 4G DDR3 SDRAM 1333MHz ATI RADEON HD 4890 Recently I decided to overclock my computer a little bit, you know, just simply raising the FBS and test stability and stuff, just to learn more about computers. The highest speed I got to was 3.0 GHz, because I’m new to this so I didn’t want to go too far, and I only got stock fun as well. My last configuration on the BIOS was this (and I never touched other configs); Frequency: 2990 Ref*multi: 230*13 NB frequency: 2100 All others are in Auto mode. I then ran Prime95 for 12h without any error, and temperature is around 44c (however when I ran prime95, the temperature raised to almost 70c), so I thought perhaps the system is stable, I then go on and played some game, Dirt3 and FIFA11. However after I entered the game for 5-10m, my computer freezes, no blue screen though, just freeze. This happens only when I play big games. So I used the jumper on my motherboard and reset the BIOS, I thought the problem would go away but it didn’t, same thing still happening. So I did some research and ran Memtest86+ as well without any error. This is where I’m up to at the moment; I don’t know where to look for problems and how to fix them anymore. Please help me get my computer back to normal. I’d never do overclock again I think… If you need more information, I’d be happy to provide. Thank you!
