Time frame: It will stay blank until power is removed. Today, for instance, it's frozen up three times, doesn't matter whether I'm online or not.
It's random, I never know when it will freeze; sometimes I'll have been working for an hour, other times it's ten minutes after I turn it on.
This first started a while after I bought it brand new (about 10 months ago) and has gotten worse recently. I was told that new computers often have problems; the hard drive had to be wiped about four months ago, and I assumed the problem would be fixed afterwards, but it continued.
No recent changes.
What should I look for in my graphic details?
