CRC errors, -repair leading to same results

After a game crash, I was prompted to “-repair” corrupted GW2 data files…. Which lead to a VerifyResults.log detailing a 8 specific bad file entries.

Duration: 417 seconds
Examined 228463 of 228463 files.
Deleted 8 bad files.
Skipped 2 files (local files, different versions, etc).

Then, the game can play with no issue.

However, trying manually again and again the repair option will lead to the exact same errors (sometimes with a different order for the error lines).

So, unless this is a known issue, I’m pretty sure that my computer hardware is flaky somewhere, but only GW2 is triggering such issues (yes, I had other programs crashing, but occured mainly while GW2 was running).
GW2 is probably quite intensive in its CPU/RAM/GPU usage and something is flaky, but not enough to bring the whole system down.

But:
– memtest86 and other RAM tests are all flawless
– CPU torture tests (prime95) dont fail
– HD bad sector check = OK

GW2 “repair” mode seems the only diagnostic tool that is able to repeat reliably the issue, if any.

(hardware being a 4 year old quad-core2 and a GTX260, rock stable up to now)

I fail to figure out the faulty component! Anybody with a clue or similar experience?

Hi Torognek

If your Crash logs are showing CRC errors, what this means is that something has caused a file to be the wrong size and corrupted the installation. The first thing we want to rule out are issues on your drive.

Please do the following first to check and repair your drive:

1. Open Computer by clicking the Start button , and then clicking Computer.

2. Right-click the hard disk drive that you want to check, and then click Properties.

3. Click the Tools tab, and then, under Error-checking, click Check Now. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

4. To check for both file errors and physical errors, select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors.

5. Click Start.

Depending upon the size of your hard disk, this may take several minutes. For best results, don’t use your computer for any other tasks while it’s checking for errors.
