Hello. I have a computer that someone built for me so it doesnt have any registration numbers or anything.I was at a friend's house the night before and when i came home i discovered that there had been a power outage from a power surge.So i just reset everything and carried on as normal. I turned on my computer later and it was operating normally. About 2 hours later my computer began freezing up when i was checking my email. It froze for a moment and then carried back on. At one point my computer made a noise like it was shutting down but the screen remained active and i was still able to do things. Then my computer restarted by itself and would not boot back to windows. I tried turning off the computer and it did not change where it left off. I tried just letting it sit overnight and trying to let it work itself out. When i checked it the next morning the screen was black and there was a message that read. "CLIENT MAC ADDR: 00 19 21 38 8A 24 GUID: FFFFFFFF-FFFF-FFFF-FFFFFFFFFFFF PXE-E53: No boot filename received." It repeated the process for a bit and when i checked back even later it said. PXE-MOF: Exiting NVIDIA Boot Agent. DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER. The only problem is i dont have the system disk and even if i did my disk drive isnt recognized by my computer. Any words of wisdom would be helpful. Thanks -Michael

get into the bios by hitting delete on bootup, look for the boot sequence, change to the harddrive. f10 to close and save settingd

I dont see a hard drive option. I only see Hard disk. And when you say look for it. Does that mean change the default settings it was booting to before?
