Laptop Dying

MERDE!!!!
My laptop is giving me the shits! Locking up at times, claiming the RAM is bad, sometimes saying it can’t find a boot device (eg: no HDD).
MERDE!!!!
The current DELL Inspiron 4100 is a replacement for my old Inspiron 3800 that kept having keyboard hassles. DELL replaced the 3800 for me under warranty. Now, 1.5 years later, this one’s starting to go belly up. I’m in discussions with DELL to see what we can make of it (other than “Don’t buy DELL!”)…
