Sounds like your RAM has died the slow death. You need replacements from us.
Here's our replacement procedure for memory.
Please go to http://www.buffalotech.com/files/Buffalo%20Replacement%20Request%20Form.pdf
Fill out the form, print it out, and fax to the phone number on the form. We require a US or Canadian shipping address.Fedex requires a signature in person and a phone number for our shipments.
Once we receive your fax of the Buffalo memory replacement form, we can initiate a replacement in our database and fax back (or email if you don't have a fax) your RMA number. You will need to put your memory in an anti-static bag/box and put that inside a crush-proof box.
Please use Fedex or any reputable carrier with tracking (scan at destination) ability. We advise that your package be insured on route to Buffalo Technology.
Buffalo Technology can not be responsible for the package until the package is delivered to Buffalo Technology USA. Product must arrive in original condition.
Ship to: Buffalo Technology

Once we receive your package, we normally take 3 business days to process your RMA, then we ship the replacement (provided that memory is in stock that day), using FedEx second day shipping. If you don't have access to a fax machine, you can email us back (to support@buffalotech.com) and supply the information requested on the form, in your email - your email request will mean that you have read the entire form and agree to comply with Buffalo Technology requirements for a replacement.
