about 5 months after I bought it my computer started getting blue screen errors. I didnt know what that meant, i thought it was a virus, and i tried to run my virus scans, but it kept on shutting off earlier and earlier so that i couldnt even start windows. Now i was really desperate cuz i thought for sure my whole drive was corrupted so i formatted the c drive (I thought i had my important stuff backed up, but it turns out I lost many important things). still didnt help. then i found out that crucial memory is famous for this. To be honest when i called crucial they did exchange it for a new one, but i wasnt willing to risk it anymore so i got a different one. Beware!
