USER QUESTION….
Windows 7 Computer won’t start, keeps rebooting, help?
http://answers.yahoo.com/question/index?qid=20120626135518AAuS8tK
The other day I was using my Toshiba Satellite L655, when suddenly it froze on me, as I tried to reboot it, it would just show a black screen. Now, I figured out that it was my Master Booter repair that had been corrupted. I have been trying to use a system repair disk, but when I use it, it comes up with country select, then I click next. After that it comes up with System recovery options, choose operating system, but it is frozen on the screen, when another box appears and is System Recovery options: Searching for Windows installations… and it is stuck from there. I can NOT get into Safe Mode on my computer, it just takes me back to reboot loop that i’m stuck in. Please help! (I don’t know much about computers so please put into simple terms, thanks)

MY ANSWER / antibotnet yahoo handle by bluecollarpc…….

You are talking a highly technical area as the MBR being fumped. (Master Boot Record). Though you say keep it simple, this is a highly technical area needing at least an Advanced User to professional to diagnose and fix. However, apparently you are aware enough to have seen or detected something and perceive the general area of trouble. The BSoD (blue screen of death) is one event. The black screen generally appears when critical and fatal corruption has occurred and other than the normal black screen appearing like when you boot into Safe Mode with Options.

If there has been irreperable damage and corruption to the system and a Black Screen appears – it will generally have a one or two liner explantion that something is totally screwed like especially something ending as SysConfig not found or similar. UNLESS you are seeing a one or two line explantion on a Black Screen and can not use the computer then it is probably not any fatal error requiring the Windows system to be reinstalled via CD Recovery Disk. So that means still a chance at a fix.

I recommend you continue in the efforts you began as reinstalling Windows as you apparently have already initiated and review online information and help about this task. If you are convinced you are performing the reinstallation process properly then this is going to wipe the disk and reinstall Windows to Factory Fresh. I own two Toshibas and they have excellent CD Recovery Disks that work flawlessly. You should NOT be running into problems with these – should be two disks either included at purchase or made from Toshiba utilities in the PC added free to make these.

As the PC has virtually become unusable – I would take the hail mary approach of attempting the drastic – wipe the entire disk and reinstall. Myself, at the point you say you are in, I would not even bother with some fix/repair option. I would go with wipe the disk and reinstall. It may be the only chance you have at getting the computer back the way you describe the situation you are in.

POSSIBLE DIAGNOSIS….
It sounds like perhaps the problem is that your computer has been infected with a rootkit/bootkit. These are about the ONLY malwares that affect the MBR area. Of course with these the ONLY cure is generally to reinstall windows after wiping the disk (completely erasing everything on the computer – windows and personal softwares and files installed). The CD Emergency Repair Disks will do that automatically and malware does not prevent this. The other repair option is an attempt to fix just an area that may have been corrupted or mistaken file deletion without wiping the disk at all – which saves all the softwares and files you have installed or created – personal files as audio and video clips, pictures, documents etc.

POSSIBLE SOLUTION….. This area is the exact new security solutions being released in Windows 8 – the new anti-rootkit anti-bootkit technologies which prevent these malwares from start up in the boot sector. There are TWO possible solutions as these two antimalware USB CD Drive products. One is the full antimalware product from well known and well awarded Emsisoft Antimalware products and FREE. The other is from Microsoft. These are first placed on a USB Drive (about 15 bucks and NOT a usb media stick – the USB DRIVE – same price) with at least 2Gigs space get 4 if you can. These will BOOT cold cokced against these very malwares (rootkit/bootkit) to quarantine them from starting up in the boot sector before the actual system is booting up. Traditional antimalware does NOT protect in this manner – but after the system start up is occurring. Make the USB Drive and stick it in and cold cok boot it with fingers crossed that this is indeed the problem experienced. If so, these should remedy this and will return the PC to normal – malware free.

Generally IRQL errors are hardware or driver related. We’d suggest
checking to see if any drivers have been updated recently and either
roll them back to the old driver or see if an even newer driver is
available (the vendor may have released a driver to fix the crashes). If
that doesn’t help you’ll find BlueScreenView, a crash dump analyzer,
rather helpful. We have a guide to using BlueScreenView to help get you
started……

It would help everything if you noticed any name of anything and go to BleepingComputer.com. I hear you and understand you understand that you knew better than to keep using the computer without taking the few minutes to create an Emergency CD Repair disk to reinstall Windows to factory fresh after wiping the disk (erase all on it). Generally with the BSoD (Blue Screen Of Death) means you have to reinstall Windows unless you are really savvy with security.

You could try accessing the Windows Registry to delete malware entries manually. Fish through system32 and unknown program installations. HiJackFree can help with these things even though you may not yet be that advanced http://www.hijackfree.com/en/ …..We are talking start up processes items (executables and others) unfamiliar and autorun entries (if worm involved) Active X items as unknowns…. HiJackFree can help simply as it lists all these – what is actually loaded and running in your pc – in each section when you install it and use it anytime.

TRY USB DRIVE PORTABLE ANTIMALWARES…. You will need a USB Drive (sometimes called a thumb drive) and these look just like a USB Media stick but make SURE it is a DRIVE to operate these. They will NOT work on a USB Media stick (same price). About 12 to 22 USD (US Dollars) depending on size. A 2Gigabyte size is plenty of room for these and usually the smallest ones and they sell up to 8 gigs and higher. (These also store files like the usb media stick).
