After Windows 7 upgrade, System goes to Blank Screen (Vaio Laptop)

I have a VGN-NW265F Sony Vaio Laptop, Windows 7 x64

An upgrade installed and now the system hangs (could be something else, I don't know, but upgrade installed right before hang)

Vaio logo comes up, then repair or start Windows regularly - If start regularly, goes to blank screen

If repair, then the sytem goes to Startup Repair and Searches for problems for hours.

If I F8

Repair, and login as owner, go to system restore, choose a restore point, and click next, system hangs. Don't have a system image or a good backup (My backups always hung. Will make sure I have one from now on)

Had memory checked. Did not change, blank screen

safe mode hangs on black screen, low res video hangs

Using Windows 7 installation disc (borrowed from a friend), the repair option hangs on "Searching for Windows Installations..." and on the other window, I can see it found my windows installation but I can't get to it, because the "Searching for Windows Installtions..." never stops.

If I try to upgrade it tells me that I booted using the installation disc, so take the disc out, restart windows, then put the disc back in to upgrade. The problem is I can't start windows! I just want to repair whatever is going on.

Help? Thanks!

If you are able to do so, follow these steps: Use Advanced Boot Options to select Repair Your Computer and get to the System Recovery Options. Then select the command prompt. Do the following:

chkdsk /r c:
chkdsk /r d:
chkdsk /r e:
chkdsk /r f:

.etc until you get the message that the volume could not be opened for direct access. For any drives that do not give the message:
"Windows has checked the file system and found no problems"
run chkdsk again as above. In other words, if it says:
"Windows has made corrections to the file system"
after running the disk check, run the disk check again.

I realize you may only have one disk show up in Windows explorer, but you may have more than one disk through recovery options. This is because the system creates a hidden boot partition (which will be C: in recovery), you may have a recovery partition for your PC that is hidden (which will be D: in recovery), and you will have your primary Windows partition (which may be E: in recovery). A custom PC will likely have at least C: and D: to scan.
