Assuming you have tried the usual battery removal/power reset. Did you burn the system disks? Since the manufacturers don't furnish them any more making your own is pretty much a given. If the unit is still under manufacturers warranty, that might be a viable way to go, if not I'd get the system disks or make a Linux/Ubuntu boot disk. At this point it is difficult to say if this is a hardware(HDD) issue or software but I am leaning more toward software/OS issue.
Hi, I have a Samsung Notebook, specs in the following link: http://www.newegg.com/Product/Product.aspx?Item=N82E16834131116
Whenever I turn it on, it won't progress past the initial screen that says Samsung. I cannot access BIOS or the recovery menu. Before this, I was running chkdsk, because I had been getting blue screens, but then it shut down in the middle of the check and now won't do anything. Please help.
