Windows7 Won't Boot

I am getting the BSOD during boot. It says there's a hardware driver problem, or hardware attached causing the problem. I can't say what that would be. I am unable to boot into safe mode. Upon booting into repair, it is unable to automatically repair. I am able to get to the restore area and select a restore point, but I am unable to click next after picking the restore point.

How can I restore the registry to a previous version?
I have System7 and Vista on this computer, Vista of course boots ok, and I can access the files on the System7 Drive.
This problem showed itself after it was shutdown.
I have had some updates prior, and installed Speed Fix Tool.

How can I repair the trouble.

What is the BSOD codes?

You say you can access the windows 7 drive while running Vista the your drive is ok

How are the OS's configured? On the same hard drive?

Need to know which code it is before we can help you out
Tony GiangrecoCommented:
Reseat the memory chips.  If you have a add-in graphics card, pull it out and reseat that also.

Unplug the Pc, press the power switch and hold it in for seven seconds.  Plug it in, turn it on and start pressing F8 constantly until you see a menu of boot options. Scroll down and select Safe Mode with command Prompt.

If it won't boot into safe mode, describe what happens.

Restart into regular mode. if you get the BSOD, write down the code on the screen like 0x123456789 and post it back to us.

I will send the BSOD msg next. Nearly all the code are 0x0000

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.

Is this a dual boot system?
Frank DiPiazzaPresidentAuthor Commented:
Yes, I can boot ok into Vista as the picture shows the DiskConfig.jpg above. Trying to boot into system give me the BSOD, even trying to boot into safe mode.

Here is the BSOD codes:

Stop: 0x000000F4 (0x0000000000000003, 0xFFFFFA800485CB30, 0xFFFFFA800485CE10, 0xFFFFF80002350470)

Here is a Microsoft page listing multiple ways to recover from a BSOD situation.

Hope it helps!

This is your hard drive is going bad

0xF4 crashes are almost always due to hardware failure relating to drive I/O,

Since you have a second drive for Windows 7 I would copy all the data you need from the D drive onto your c drive or usb drive then replace the drive install windows 7
Tony GiangrecoCommented:
The first code F4 points to a hardware failure. It's interesting that Vista boots and not Win7. I'd boot into Vista and run a checkdisk /f on both drives. You may have bad sectors on the D drive partition.

Also, in Vista, check the System Log in event viewer for disk errors. Filter the log for everything except informational.
Frank DiPiazzaPresidentAuthor Commented:
As you can see from the DiskConfig.jpg, it is a 500Gb HDD, partitioned, with Win7 on one, and Vista on the other partition.
Thomas GrassiSystems AdministratorCommented:
As I posted your hard drive is going bad best to get the data off ASAP get new drive reinstall win 7 os
Tony GiangrecoCommented:
Yes, but your hard drive appears to be going bad. I suggest backing up your data before it does and doesn't want to boot at all.

I have discovered some potentially leaking CAPS on the mainboard. They are domed, so I suspect a failure may be due. It bothers me that Vista boots ok, but not System7. I am running a disk check on the System7 partition now.
Frank DiPiazzaPresidentAuthor Commented:
Results do not indicate a problem with the drive.
Thomas GrassiSystems AdministratorCommented:
Yes check disk will run and give you good results even when you may have a problem it is not the best utility to check the physical drive need that from the manufacture

What happened is you lost the boot sector for win 7 that is why you can not boot into safe mode

As long as you can access the d drive again copy backup your data and replace the drive
post the dmp file plse - find it in windows\minidumps, when booted into vista

This is what I found. a 131mb Memory.dmp, and it can't be uploaded.

Here is a compressed version.
it says :

it seems you found the problem:
"I have discovered some potentially leaking CAPS on the mainboard. They are domed, so I suspect a failure may be due.    << you cna repalce all the capacitors, or have them replaced in a shop - or install another mobo
>>   It bothers me that Vista boots ok, but not System7.  <<    that can be because the OS is very different, and handles hardware also different

are the OS'es on the same drive, or different ones?

you can run a diagnostic on the drive  (chkdsk is not a disk diagnostic; it's a file system diag)
i use UBCD a lot for this - you find all disk diags + lots of other software :
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 :

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)                        ultimate boot cd             download page

**  you can make a bootable cd - or bootable usb stick

for completeness -here's how i handle disk problems :

So disappointed the ACER mfg uses marginally acceptable capacitors. This has been a repeating failure from this company.
if these are electrolytic ones - theay have been used by every manufacturer - not only Acer

I replaced the mainboard, and I'm still getting:

I finally found the solution, and the problem was a corrupt Registry.  Here is the solution and I'm back running again.
I'm thinking a Registry defrag tool may have done this damage, but I'm not sure.

...this would be a last-last resort before reinstalling Windows 7.
Using a Windows7 Upgrade disk, I booted the system, and then went to Command Prompt, then C: from X:

CD \windows\system32\config

"dir RegBack". See what the time/date stamp is on the hive files there. If recent (use your judgment), do the following to restore that backup registry:

ren default default.bak
ren sam sam.bak
ren security security.bak
ren software software.bak
ren system system.bak
copy RegBack\*.*

Seems quite a few people have had my problem, back a few years ago.

Corruption occurs from disk problems

I would still look into replacing the hard drive soon
