black screen with moving cursor on startup
i have a problem, that later i learned that it was called "black screen of death"; when i bootup the system i can only see a black screen and a movable mouse cursor, but nothing to do.
i think it happened after i disabled lsass.exe from startup in msconfig with many other things.
i don't want to format my computer, and i don't have a windows vista cd, only acer's recovery cd, that turns the system to factory defaults i suppose; and windows recovery cd that i found from internet.
i found some solution advices in different forums and in virtualdr as well, but none of them helped me. first of all my system:
acer aspire 4720 / windows vista home edition
* Intel® Core 2 Duo T7300 (2GHz, 800FSB, 4MB L2 Cache), Intel® GM965 Express chipset,
* RAM: 2GB DDR2
* Harddisk: 160GB Serial ATA
* 14.1 WXGA Acer CrystalBrite™ TFT LCD
* Ekran kartı: Intel® GM965 Express Chipset
and what i tried till now:
1. clicking shift 5 times hoping a popup about the sticky keys will popup. nothing happened but a funny sound. / ctrl+alt+del does nothing either.
2. safe mode, no difference.
3. system restore, all the restore points gave an error. / and none of the alternatives in windows recovery were useful.
4. starting with system recovery, i could reach regedit. i tried to add lsass.exe to "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run", no difference.
5. when i looked to "HKEY_LOCAL_MACHINE\MySYSTEM\ControlSet00X\Services\RpcSs" (detailed explanation on http://www.logicitc.com/blog/?p=102) value on ObjectName was what it should be: "NT AUTHORITY\NetworkService"
do you have any advices? please help.
Thanks.

You have been infected with malware
I'll mov this over to the Security forum, where hopefully you'll get the help you need.
Nick.

i scanned my pc with nod32 and ad-aware, they couldn't find anything.
then i tried to clean some useless or non-working stuff on startup, because of the slow boot, and errors at startup, and this happened.
i think my problem is something different.

nod32 and ad-aware [very very old] are just a start.
Read and follow the instructions here.

If you have several known and unknown issues, starting over is often the best thing. Yes, there is pain involved but the end result is that you have a machine that is factory new again. Trying to repair/trouble shoot things like this takes more time than you sometimes realize.
I've sort of been where you are now and lived with a somewhat ailing PC for quite a while. Once I bit the bullet to start over from scratch, I kicked my self over and over for not doing it sooner.
If you do decide to start over, don't forget to save your data (music, photos, etc.) to a 2nd drive/CD's/DVD's.
Best of luck!
