    Power surges can and do fry PCs, or parts of PCs.
    I look after a lot of computers and have never had any serious problems with Dell. You can also talk to humans at Dell!

    Arguing about surges is getting sidetracked from the problem, the description more likely indicates a corrupted windows install rather than a hardware failure at this stage. Whether it was cause by a surge or a interrupted power supply is largely irrelevant, if the PSU is faulty and caused it that's a different story. Perhaps the OP could describe what he considers a "surge" to help decide if that's what it was.

    KarameaDave's post was the only very helpful looking one to me, Wainui's was accurate and informative but doesn't help with the problem.

    Getting back on topic, the prompt to do a repair install is usally caused because windows has failed to start-up or shut-down properly previously. As pointed out you should always try the start windows normally option first before attempting a repair. Having tried the repair and failed you now need to try again. Using a linux CD and retrieving files first is a good Idea.

    If possible another option would be to connect the drive to a working machine and run some hdd diagnostics to confirm it's ok, even a simple scandisk/ checkdisk scan can sometimes fix these issues (but probably not after attempting a repair).

    If windows is failing to boot even in safe mode you probably need to boot off the windows CD and do a repair install from there, or possibly even start over and install fresh. Running some diagnostic tools to check the memory and hard drive would be a good Idea also. If a repair or install keeps failing without completing then you possibly do have a hardware problem.

    KarameaDaves post has good suggestion, but the OP still has not replied after doing the original post.

    What is a bit of a worry was the comment:
    There is also a descending high pitched sound that sounds like a cd rom failing to read a disk (No I'm not booting from disk either)
    Not good. could mean parts failure, but without more info its only a guess.

    A power outage, or blackout as westom puts it, -- More like a whats know as a brown out, (drop in voltage in an electrical power supply) as a blackout is usually referred to with a total power cut cant do any damage, the damage is done when the power comes back and the is higher than normal. Saying it doesn't happen is rubbish. I have a PC here, they had a spike/surge ( no ups on this one), it blew the PSU in the PC, blew the Microwave, damaged the TV and tripped the UPS surge protection on another PC, and tripped several overloads in the main fuse board last week. I have since found out that several of their neighbours also had items damaged.

    Yep, happens frequently here in Karamea (brown outs and surges) and lots of lightning lately.

    Nobody said a surge 'doesn't happen'. A surge probably existed due to hard facts. Such as multiple damaged appliances and neighbors with damage. Damage was not due to power loss. Power restoration also does not cause a voltage spike. Damage is typically due to a surge that preceded and may have also caused a blackout.

    OP has no reason to believe his damage was from a surge or from a power loss. His failure is typical of a manufacturing defect. To say more requires hard facts. For example, from the manufacturer's comprehensive diagnostics or diagnostics from bootdisk.com. That quickest, easiest, and most informative solution also does not put existing data at risk.

    Solution starts by not even disconnecting one wire. Best solution means immediately knowing the anomaly is only in hardware or software. Until the OP provides those facts, then further discussion is only hypothetical speculation.

    So going by Westoms theory, power surges dont actually exist except and I quote
    Destructive surges occur maybe once every seven years
    and every electronic component that has failed due to some sort of power fluctuation is actually a manufacturing Defect -- give me a break.

    While power problems may not be a surge in the OPs case, a power drop, brownout CAN damage a operating system and cause corruption.


    Lots of data recovery programs, dont come from bootdisk.com. There are many from various places, its a matter of using what ever works best along with the knowledge on their use. Sometimes if a person doesn't know how to use a program, no matter where it comes from they can actually do more damage and lose data.

    Some statements quickly identify urban myths purveyors. A denial without numbers quickly identifies myths. For example, what is normal voltage for any computer? Incandescent lights can dim to 50% intensity. Every electronic appliance must even startup when voltage is that low. It was required even with the very first PC. Computers must startup normally even when lights dim to 40% intensity.

    Why do lights not dim that low? Utility cuts off power if voltage is that low. Because a voltage that low is potentially destructive to motorized appliances. But not to any electronics.

    Again, international design standards more than 40 years ago describe all low voltages with an expression in capital letters: No Damage Region. If low voltage did cause hardware failure, then his computer would not even power on. Llow voltage never causes electronics damage. Unexpected power loss did not damage any disk drive even long before PCs existed.

    OP's best and most useful solution started with diagnostics such as from the manufacturer or bootdisk.com. Diagnostics are not for recovering anything. Best is to never fix anything until a defect is first identified. Otherwise data is at greatest risk. Best is to use recommendations from someone who was fixing this stuff long before the IBM PC existed. What works best always starts by discovering a defect long before trying to fix anything. Otherwise a problem can be made exponentially more complicated.

    Too many want to fix something without knowing what has failed. Then assume the resulting data loss was unavoidable.

    Stop being such a twat -- You seem to believe that any power drop, cant cause corruption which is what I said.

    Well sorry sunshine, no idea what planet you're on, but I've seen it happen hundreds of times, power drops for what ever reason, computer crashes, corruption occurs. Data corruption also can happen if a computer is doing some updates or altering settings and power is cut turned off, once again seen it hundreds of times.
    Why do you think Windows displays a message sometimes when installing updates " do not turn off your computer - it will turn off automatically" MS dont put that in for fun or to annoy people.

    Since you seem so sure of yourself, then you had better contact http://67.199.80.115/Power_surges.htm and tell an actual power related company that their entire website and company is wrong.

    Too many want to fix something without knowing what has failed. Then assume the resulting data loss was unavoidable.
    Thats about the only thing that makes sense. I have a Drive here, a friend in Auckland took it to someone who works in a computer business, they said it was totally destroyed, all data lost. So Far I've recovered 20 GB worth of family pictures, and there's more to come yet. The drive has many unreadable sectors.
