Guild Wars 2

I have my pc overclocked and was wondering if this could be the cause. Whenever I start the game up, I can choose my character, but once I get in game, I either freeze or receive an error. This is the latest I received.

—> Crash <—

Any help would be appreciated.

Whats your system spec? Drivers up to date?

Motherboard: GA-Z77X-UD3H
CPU: Intel i5-3570 @3.4, OCed to 4.5
Heatsink: CM Hyper 212+
GPU: EVGA GTX670 FTW 2048MG GDDR5 256bit
Ram: Patriot extreme masters 2x 4GB
PSU: Corsair TX 750 W
Storage: ADATA Sx900 256 GB SSD
Secondary storage: Seagate Barracuda 1TB
Case: CM Scout
OS: Windows 7 64-bit.

I believe everything is up to date; everything in Device Manager looks fine.

I just ran memtest86 for almost 2 hours, and it passed 3 times with no errors, but on the 4th, it froze at 18%, time and everything. Not sure if this means the stick is bad or what, but I seem to only get this error when I would try to OC. I do occasionally get random BSOD on stock settings, so something is making my system unstable, but I don’t know what.

I forgot to add, I am back at default settings. I lowered the vcore voltage too much and had to reset settings via CMOS.

grab the latest version of evga precision if you have it running.

older versions cause a crash because of the overlay
