Windows 7 keeps rebooting

Hi Guys

I have a windows 7 machine which keep rebooting and tries to repair startup. Although it is a fairly common problem the odd thing about this one is when I go in to the repair options and select memory test, it runs and I can logon after a reboot?

I can logon and do what ever I need but each time I reboot it does the same thing, reboots and wants to repair. It has 2 memory dims, I have removed each one but still the same thing?

PLease check the RAM with local vendor.
Along with this have you read the error when the memtest completed?

Also You can use hiranboot CD to test the memory again.

Along with this can you verify below registry key once it should be blank:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\BootExecute

As already noted - this could be caused by heat and it could well be that you are infected, although that doesn't seem likely.

I would start by opening the computer and using canned air to blow out all the dust. Be sure to blow it through the power supply. Keep blowing from different angles until no more dust comes out.

Remove the memory from the motherboard and blow out the channels those go in. Blow off the memory itself and then reinsert be certain that you hear a solid click when they go in. Note also that they can only go in in one way, that there is a notch on the part which goes into the channel that will not let you put it in backwards.

Make certain that the fan on the CPU is functioning properly and not locked up. Blow the heat sink free of all dust.

Disconnect the video card and completely blow it free of dust, paying careful attention to the heat sink and fan. Again, blow out the slot it fits in. Reinstall the card. with the case open so you can see in, plug the machine back in and turn it on: does the fan on the CPU turn as it should? Does the fan on the graphics card turn? If either of them don't then that is likely the cause of your problems and the fan needs to be replaced.

Failing all other solutions, I suggest backing up your data and performing a system restore to factory condition and checking the performance after that

Ammm.... I understand what you are saying however if it was hardware & in particular heating or the seating of memory I would suspect the machine would behave the same way no matter how I boot.

the only way I can get in to the computer is for it to reboot, then except the option to repair startup, then from System Recovery options I select "Windows Memory Diagnostics" it runs once it does a reboot and says that a log will be displayed - which it doesn't.

After it reboots once the memory diagnostics has completed I can logon in normal mode - if it was heating or anything else physical I would not be able to logon and stay logged on for as long as I want

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Use the official DVD and do the system restore to previous month or oldest restore points.

the repair comes probably from a disk problem, so i suggest testing the disk with the manufacturers dis diagnostic
you find all on the UBCD;
 i suggest the UBCD  to run some diags first - to be sure about the basics

Hardware diagnostic CD    UBCD

go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP : http://cdburnerxp.se/

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
 
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)

OK not really helping, thanks anyway. I will do a rebuild - was hoping to avoid this.

Sorry - a bit hasty..... I didn't see the response from "nobus" - will try the disk tests.

Ergs--
Did you do a System Restore as was earlier suggested?  Now that you are able to get to Desktop you will not have to use the Windows DVD to do this.  But you will have to choose a date before this all started.

And here is a procedure to use if you are still in an infinite loop when using Startup Repair.

The System Restore should help if the infinite loop problem started right after you installed a new program or hardware.

Guys I spent too much time on this problem, I have since done a re-install. I do have a certain amount of knowledge, I am an IT consultant, this was a job for one of my clients.

System restore was failing, I couldn't do anything.
* Unable to login to safe mode
* Unable to perform a successful restore
* Check Disk - no go

What I found was that the system would allow me to logon if I did a "Windows Memory Diagnostics" from the recovery options (tried everything else without luck) - never seen this before.

It was for this reason I believed it was not a hardware problem, I would expect the error/problem to be consistent. I'm sure it was some sort of software problem as I have done a reinstall and it's been running fine for many hours.

>>  Check Disk - no go   <<   what disk diag did you try?  did you make the cd and boot from it?  what happened ??
i'm sorry to say, but you gave no info; no go does not tell us anything to go on

A Repair Install might have been less painful.

You did not give us much time (less than two days) and only leaked out info little by little.
