vista will not boot, stops at aswRvrt.sys

[REDACTED]

  I am at a loss.....perhaps Essexboy has an idea ?

I would get (download/burn) one of the Rescue CDs and boot into that environment and try to debug what is going on.
Like Essexboy it appears to me to be graphics driver related.....but a guess at this point I must admit.
At the very least you can use this Boot/Rescue CD to copy off any files you need to as a backup in case you have to re-install O/S.
Once you boot the Rescue CD I would try to uninstall the gfx driver.....you want to get to basic Window default driver level.
The idea is Windows (your Vista) will use its generic gfx driver to boot to Normal Mode....you can get/re-install your specific driver later.
I would recommend Hiren's BootCD: http://www.hirensbootcd.org/hbcd-v152/
Read section on Device Driver Tools.
Examples:
◦Device Doctor 2.1: Scans the hardware and checks to see if there are new driver updates available, also checks for the unidentified devices (Windows Freeware).
◦PCI 32 Sniffer 1.4 (18-10-2012): Device information tool which is similar to unknown devices (Windows Freeware).
◦Remove Non Present Drivers: Automatically remove all non-present/disconnected devices from a Windows and can often be useful to prevent misbehaving/unnecessary drivers from being loaded, (Windows Freeware).
◦UnknownDevices 1.4.20 (18-10-2012): Helps you find what those unknown devices in Device Manager really are (Windows Freeware).

You can select/run the mini-XP environment once you boot from the CD....once loaded browse/use tools (I list some above examples that may help).....but do some Googling on the tool you are going to run to make sure you understand it first.  BUT, before you run any tools I'd copy off any files using the My Computer.

Here is tech spec of your Lenovo Ideapad Y550: https://shop.lenovo.com/ISS_Static/WW/AG/merchandising/US/PDFs/yseries_techspecs_110909.pdf
Is it the GMA (Intel Gfx) or NVidia one ?

Probably the quickest option will be to re-install

If it's the video card itself, it would be a little hard to do much of anything since all you get to see is the black screen.Video cards aren't that expensive and it may be wise, if all fails, to invest in a cheap one just to make sure the video card is the problem.
Essexboy, what do you think

[essexboy]

Definitely a cheap option I feel

But OP's system is a laptop (Lenovo Ideapad Y550)........thus, no gfx "card".
However, I like the idea.......what I would do is go to FRYS or Best Buy and get a USB-to-RGB (or USB-HDMI since he has no monitor) dongle and try....only because these come with their own drivers installed. If the O/S truly is "up" then the USB driver within the dongle should load and maybe you get a screen....then can debug on the true O/S-system.  OP can return the dongle within 30-days when he no longer needs.

The Rescue CD above is at least a way to get his files before he re-installs the O/S and loses his info.

#2 doesn't have a link to download the file.

Essexboy will PM you the link.

Hello guys. I'm concerned as well by that problem. I tried to follow the different steps but I don't have a link to an .ISO to feed RUFUS. I have a VISTA family version installed on my ASUS laptop, which means I don't owe the CD. I' ve been searching for awhile and found numerous suspects links. So could you please help me? (My troubles are the same : unable to boot even on Safe Mode. )
Thank you by advance
