Windows 7: Computer freezing during bootup.

Computer freezing during bootup.

I can't seem to fully boot into windows because it always freezes with everything I've tried. I installed a new SSD with a clean install into my computer today. After a couple of hours of updating drivers and windows updates it won't boot properly. Passes the bios part and POST every time. When it reaches the "starting windows" screen it always freezes. I tried it with my original HDD and it freezes at the same part. I've tried going to safe mode and it freezes when its loading up the list of drives or other files screen. I've tried doing the system repair at start up, the bar fills up and says "loading files" and freezes there. Tried booting to dvd to do reinstall and freezes the same way the system repair does. Also I can't seem to boot from my usb flash drive on my desktop. When I tried to it would have a black screen with the blinking cursor/underscore.

So booting from win7 install DVD freezes as well on "loading files"?
How many disks are in system... only original HDD and SSD?

It didn't boot succesfully all of a sudden. You didn't open the computer and accidently detached a cable or damaged your memory just before?

Try booting from win7 install DVD after detaching all disks from system. What happens then?

If successfully attach only. Afterwards try to boot again.
Attach the second disk as well. Afterwards try to boot again.

Now you know what disk causes the problem.

If boot freezes with no disks atached: attach the disks again.

I don't think I damaged my RAM because I didn't even touch my motherboard or the RAM and I didn't open my computer or removed any cables after I installed my SSD. It was working fine for a bit. Then after a mandatory restart after the windows updates and the other drivers, it wouldn't boot. I didn't touch anything inside while doing my updates. I tried booting with no HDD/SSD connected and booted from Win 7 install DVD. It was able to pass"Windows is loading files" screen with bar full and when it reaches "starting Windows" it freezes there.

edit:
I decided to check if my RAM was causing the problems so I removed 3 of the 4 RAM sticks. It seems that it was causing the problems. As of right now I have one RAM stick plugged in and was able to successfully boot into windows. I'm currently checking the RAM slots to see if any of them are broken then I'll check the sticks individually. I'm not entirely sure its my RAM because I never touched them when installing my SDD so how would it end up broken or causing my computer not to fully boot.

edit:
Okay I have no clue what the cause is. I don't think its my RAM anymore because they work in another computer. Trade RAM and it still didn't work. Decided to remove every connection besides my monitors and keyboard my SSD and optical drive then all of a sudden it works. What I disconnected was my HDDS, my usb mic and bluetooth dongle. Trying to figure out what the cause was by putting one more thing back at a time

Anyone have an idea of whats going wrong? Whenever I have my HDDs connected and my other usb devices connected, it freezes at "starting windows logo" screen. When I don't have my HDDs and my other usb devices disconnected I can boot fully. Then when I'm at my login screen I just plug in all my devices then it works normally. When I only have my HDDs/ USB devices pluggged in it freezes. I have to have both disconnected before I get to the login screen.

Have you tried swapping the power cables around?

I had a problem with a dodgy power cable/connector on one of my DVD drives, which prevented my computer from booting from the HDD (the symptoms were similar to the ones you describe).

The weird thing is that particular setup had run without any problems for a couple of years and then it suddenly started playing up.

No extra power cables or unused ones in the computer. I did make sure that it was connected all the way and made sure that the others are connected as well. Is there anything I should replace, my computer is about 3-4 years old would the power supply be going out?

I would go back through your computer and check all your connections. I experienced an issue a while back and I swore that I didn't touch anything else, but turned out that I had somehow loosened a cable connection. This is especially possible if you don't have clip locking cables.

If there is damage to your components you most likely won't be able to see it. Be wary of ESD (electrostatic discharge) while you are poking around the internals.

When you install your OS have only the SSD connected during the installation. Install all your updates and drivers with all non-essential externals disconnected. It is possible that there is an update or driver that is causing the problem. This can be a time consuming evolution depending on how much you have to install, but to rule out bad drivers and updates I would install one (or a few) at a time, reboot and check performance. Wash, rinse, repeat until either you recreate the problem or hopefully never experience it. If it is a bad(incompatible) update, installing updates and drivers in small chunks will help you narrow down and identify which one is causing your problems. Once all updates and installs are complete, reboot reconnect and assess.

If this is helpfull, or completely useless to you, let me know either way.

Seems that you caught on to a possibility... the power supply could be a single point of failure.

What is your power rating? If you have a low wattage power supply you may be trying to use more power than it can put out. The more stuff you plug in the more power you demand from your supply...there comes a time when you reach or exceed that limit. This can be dangerous for your system.

So 2 possibilities in the realm of power:
1) Bad power supply
2) Not enough power for your system and all externals.

I'll Double check the cables probably tomorrow when I have the time. I don't think its an ESD problem because I always use a ESD strap attached to the case whenever I touch sensitive parts and then put them in ESD bags but there is not really a way to definitely sure. And the drivers thing does sound like a likely answer but I'm probably gonna ghost my SSD and then the install so that may take a couple hours so I probably won't have results to tell you ydylan77 probably a day after tomorrow. Um so should I install like my windows drivers all at once then go to my other required drivers after that one at a time?
