Windows 7: freezing, but no BSOD... windows 7 will not boot

I installed Windows 7 a few weeks ago and then installed a video card without any issues. About a week later, I added 1.5 GB RAM and again did not experience any problems. The other day, Windows completely froze; my cursor would not move. Ctrl-alt-delete would not work, so after 5 minutes I shut it off manually on the front of the computer. The next day it booted fine however it did freeze again, so I hit the power switch.

Now if the computer even starts, I get to a page where it tells me that I can either run windows repair or start windows normally. a normal start up does not work. I ran windows repair, and it couldnt fix the problems under the start up menu I am assuming; it did not find any errors in the memory though.

Finally, I took out both the new RAM and video card and it was unsuccessful.

Any suggestions?

Please rerun the Startup Repair.
When it finishes there'll be a link to see the details. Please copy/paste the details into your next post.

What memory test did you run?
Try running a free hard drive diagnostic: HD Diagnostic

I hope this is what you were looking for, I cant copy and paste b/c I cant access the internet from that computer. I had to write this down.

If you were referring to the other details link, there is no way I could have written all that down, so I scanned it to find the important details. It said that each test was completed successfully and at the end it says, "Unspecified changes to system configuration might have caused problem."

As for the memory test, I ran the one that was included in the Windows Repair. hope this helps. thanks.

quick update, I switched my hdd to the computer I am on now and everything worked fine. windows 7 booted up as usual. theres something wrong w/ my actual computer itself, but Im not sure what.

The actual details report is the same as what you've posted - the format's just a bit different.
The key here is the System Disk thing.

If the Hard drive works in another computer, then the hard drive is presumed to be OK
So, the System Disk thing can't be the hard drive - so then it's gotta be something in the motherboard (such as drivers for the chipset) which will affect the system drive.

Put the hard drive back in the other computer and run the Hard Drive diagnostic that I linked to previously. If it passes (as I suspect it will), then we'll have to work on the chipset driver issue.

Hmm.... Have you tried to get in safe mode and use windows restore?

I have an old pc i use it much for fb, msn, xfire some games and most for homework
i was using Xp, then vista
So i heard for Win 7, my friend sayd that it is for older pc while its using less ram and that things
So i tried it now i have a problem. I started 7 and i didn't had the 2nd part of my hdd 160GB 30 was for windows and other programs, 130 was for games and homework
i haven't see the 130 GB so i figured it out, i had to add a letter to that part it was easy
but the pc now freezes every 5-30min even the mouse freezes i have to restart it manually. I have an old pc 2.6 GHz pentium 4, 3 GB ram, 160 Hdd, and an ati radeon 9550 / x1050 series 256mb

Even with this configuration I'am able to play WoW, Hon, CoD2 and 4 and even Crysis
If you have any idea sloving this problem..... Sorry I'am not good in English

Did the 1.5GB of memory you installed match what you already had in the board?

We weren't sure how to access safe mode with Windows 7. I did not get an option and F8 did not do anything. Anyway, I could not do Windows Restore b/c apparently it had not saved or something. Whatever the case, it would not work.

Yes, the new 1.5 GB RAM was exactly the same as what was previously installed. all four sticks were the same brand, all 512 MB.

Later on when I get the chance, I will put my hard drive in this current computer and run the test you posted.

However I bet there is something wrong with that motherboard. Once I had a slave hdd in there and it just disappeared. Nothing is wrong with it. Also, I cannnot get any DVD- or CD-ROM drives to work. Ive tried switching different drives, ribbons, etc. but nothing works. It wouldn't surprise me the least bit if the problem is in the motherboard.
