Hey guys, when I got home from school, I went to turn on my computer which was off at the time of the outage and it took a very long time to boot up but after it booted it was fine. I had known about the outage because my I often was flashing and also my microwave was also flashing. I Rewrote my bios and ran a chkdsk /f and a ssc /scannow but they scan didn't fix the problem and the rewriting of the bios didn't fix it either. However I did notice that the rewriting did seem to take longer than usual. The bios takes a long time to recognize hardware and after the four windows blobs meeting clip there is a black screen that last very long until the login screen. And ideas? Thanks. I am on windows 7 ultimate. I do not suspect hardware damages since I had a surge protector with the computer.

What kind of power supply do you have, some power supplies have built in anti-surge protection. Also, is your computer plugged into an anti-surge power bar, these are factors to prevent voltage spikes. Does your computer still operate normal i.e temps, fan speed, voltage of the PSU, voltage of the CPU...
My computer was turned off at the time, and I have a shuttle system so I use the included power supply. The power plug that was plugged into my power supply was indeed plugged into a power strip WITH surge protection. Temps are fine, and once i login everything is normal and not slow.

What type of internet do you use? Cable, DSL, Fiber, other
If cable or dsl, is your main connection from the outside plugged into the surge protection? So the coaxial cable or the phone cable.
Was your cable modem/router plugged into a surge protector? Where they on or off when the outage occurred?
A network interface can be damaged very severely if all the paths leading to it are not safe.
I lost a modem, router and 1 nic when a lightning strike hit on my block about 3 years ago.
It can also still work even when damaged and might case the system to take longer than normal to boot.
Put your internet connection under stress and see what happens.
After that you will have to start checking individual components with software to make sure they are running at the rates they should.
CrystalDiskInfo for your HDD would be useful to have anytime.
Something to confirm that your CPU and ram are all recognized correctly, like CPU-Z.
Good luck. At the very least your system still works reasonably well.

Hello, I don't think the networking would have affect my computer since it was not connected to the network at the time of the outage (since it was turned off) I have ATT U-Verse. Should I re install windows if nothing else works, since it is the most likely solution that will work? Thanks I just check CPU-Z and everything is fine. so that does lead me to think that I may need to re install windows.

Ok so you have fiber, great. A charge would not travel over the line coming into the building.
The connection to your computer, is it wired or wireless?
If it is wired, then I would still suspect the nic if the external modem was on during the surge. Inside your home you use Ethernet cables.
Is your modem and router plugged into a surge protector?
A reinstall of windows seems like it would be one of the last steps to take if like you say "The bios takes a long time to recognize hardware".
But in general the timings you are giving for it taking longer are hard to interpret. It could just be that you think there is a problem so pauses seem to take forever.
TLDR: If your router and external modem are not plugged into a surge suppressor AND you use a wired connection for the machine, a surge can effect a computer with the power off because the network cable is still plugged in.

Hello, I have a wireless connection between my ATT router/modem and the computer, so that is not an issue and my Router is connected to a UPS, so even if my computer was connected it wouldn't be an issue. However, I can agree with you on the "seemingly slow" moments, however I can CONFIRM that it is slower. I know the BIOS takes a long time to display the hardware, but the longest that the system takes to boot up is from the 4 blobs making a windows logo to the login screen where its just black screen for 2 min, system usually takes a couple of seconds since my ssd.
Hello again guys, I played around with my computer and managed to get it to boot normally a couple of times by swapping the SATA power (and maybe DATA) connectors, but however, right when I put my case lid on, it would go back to booting slowly. I have no idea why this is happening; any ideas before I re install windows?

I'm having this same problem now after power failure. Curious to know if reinstalling will fix it.

Hey dudibd, I fixed my problem but I can't remember if it was because I reinstalled my OS or because I replaced my RAM. I did those around the same time because besides Windows booting slow I was also dealing with blue screens caused by faulty RAM(which memtest86 found no errors with by the way).
If you have multiple RAM sticks, try booting with only one of them and unless the problem is fixed try the next one. If that doesn't fix it reinstall Windows. Good luck.
