|Can you get into safe-mode (press F8 after the initial splash screen)?|
Equally if you can get to that safe-mode menu - there will be other options there too - try Last Known Good Config?
Incidentally I'm suspicious about the M$ Registry update.. I'm wondering if you go hit by something not from M$-land?
On the laptop I'd be seriously inclined to scan that system - fully; both from within windows and without (windows not booted up). More of a safety aspect but better to be safe (now) than sorrier (later)...
Download and burn to a DVD the Kaspersky Rescue Disk ISO. Boot with that DVD. It will load itself into RAM only; then go online to update itself. Having done so it will scan the entire hard drive and deal with anything nasty it finds. There are assorted pests that hide within windows systems and avoid detection by most utilities running within windows. Kaspersky not running within windows (it's a Linux based disk) is thus able to find them and deal with them.
and this is a very complete guide re' using the Kaspersky Rescue Disk:
Having done the Kaspersky routine I'd then download and run - in this order (as per Derek's advice):
Junkware Removal Tool (JRT)
JRT installs to the desktop; from where you run it. It opens into a small dos style window; follow the instructions therein. It will reboot the system asa part of its process.
Install each utility using the "manual/custom" option; do NOT use the automatic option. When you use custom you can uncheck all those little boxes "so helpfully pre-checked" for your "convenience. Those (pre-checked) little boxes allow a whole slew of "stuff" to be included in the installation; stuff you don't want or need, and which often is PAI to get rid of.
I'd also ensure (even for the laptop) that "all" your personal files on that system are also safely copied elsewhere - typically DVD but an external hard drive too is nice(r).
You might also run the Kaspersky Rescue Disk on the PC as it will clean that out to some degree too. Then see if it will boot at all into safe-mode or Last Known Good Config (if it won't as earlier above)?
On both systems, retain any logs generated - incase of further input/need anon...
On the PC - can you get into bios settings; and if so are they as they "ought to be". Is the hard drive detected/running (can you hear it)?
Is the video onboard adapter enabled in the bios; as if you have removed the add-in card then the system may not have reset to to the onboard adapter?
