I got that yesterday as a friend came with his machine. Changed the Memory, he used Kingston Hyper X, to Geil and things were working well!
Got this on my desktop, which isn't setup at all yet (no graphics drivers, hasn't been connected to the internet, and was idle for a day or two). Haven't seen it on my laptop yet (updated, drivers, set-up).
Desktop x86 and x64 Activated - none activated, VM only. 2GB, 4GB. 8GB ram, Modified, none modified - no matter what,
