PC will not Start Up

[Barnum]

Suddenly my PC will not startup. I get the screen saying "Windows Starting" but that's it..... When I shut down the PC (start button) it comes back to the repair/start normally screen but I am unable to use the down arrow to start normally.

So....I have to wait about thirty minutes for MS to try and repair the problem, which it cannot. I then do a system restore which takes another ten minutes and I am told that system restore did not complete successfully, and the error Ox800700b7.

The process closes, windows starts again and opens ever so slowly. I am then told that system restore DID complete successfully? I can then use the PC normally.

Last night I shut it down, gave it ten minutes and it started up fine. I thought okay it was just a one time glitch, but this morning the same routine all over again. Repair attempt, system restore (at least an hour total), and I am using it again. What could cause this, and how do I fix it? My PC has all the HD space all the memory I need and is relatively new.

Hi Barnum, may I suggest you open cmd prompt with admin rights and run sfc /scannow and after that install Microsoft Security essentials and run a full system scan.

I would run a diagnostic on the HD while you still have the chance to image your system off of it to an external. Which I would do in any case.

How do I run a diagnostic on my HD?

 

[Barnum]

And with the scannow I get the message I must be the administrator. I am the only administrator and user?

 

[Barnum]

Okay, I have no idea how to do either of these things. I tried the scannow and it says I must be the administrator and run this in the console. Can someone please tell me what this means. Again I AM THE ADMINISTRATOR AND THE ONLY USER.

Open command prompt as an admin and you will be able to run all the commands

 

[Barnum]

Let me try this again....I am the admin but when I go to the command prompt it say I must be the admin....so apparently it is not recognizing me as the admin.

Okay, I finally figured out how to run scannow as admin. I ran it and it said that it found corrupt files but unable to fix them as in see C:\Windows\Logs\CBS.log. Now what do I do?

You may need to run it 3 times with a reboot after each run.

You do remember the problem I have is starting my PC? How am I supposed to do it three time?

In addition to the excellent advice previously given I like to to start with the physical rig first and have you open and inspect for a good cleaning and to unmake and make all connections. Blow out all fans and cooling fins on CPU, PSU and GPU.

Did you use Option One in the tutorial?
However you ran SFC, can't you run it again the same way 2 more times...?

 

[Barnum]

Okay I was able to "restart". Is that the same as reboot?

 

[Barnum]

Is it possible that dirt inside the PC would cause this problem? Remember when I do a system restore I can open it. If it were dirty I would think neither would work.

Yes

 

[Barnum]

Okay I will run scannow a couple more times, but why does it take three times? Also I do not have a Windows 7 disc. It came preloaded on my PC.

 

[MourningStar]

?... Also I do not have a Windows 7 disc. It came preloaded on my PC.

This statement sounds as though you suspect you may have to do clean install. Hopefully you have a recovery partition. You should be able to burn your recovery discs from it. Do so ASAP.

Just saying you start with physical first as they tend to be 90% of issues. Heat fry's electrical components. PSU's start to go and short the mobo, voltage spikes fry ram and GPU's. It sounds like you don't know when you got into your rig to clean it or you'd have mentioned it. This leads me to think it's dirty and like many who come here for help a simple dusting is a minimum every 3-6 month routine that's almost never done. Inspection of the rig is key but may not be your issue but I'll guarantee won't hurt !
