Vista - System crashed please help!!

My windows vista crashed for no apparent reason and it will continuously direct me to a black screen with an option to continue normally or launch startup repair.

Normal startup doesn't work, and the repair gives me the message "cannot repair this computer automatically". I send the info to microsoft and it gave me no options to fix it

And although I have attempted the repair several times already, for some reason it says number if repair attempted:1

Root cause found:
----------------------------------
Startup Repair has tried several times but can still not determine the cause of the problem."

Root cause found:
----------------------------------
Unknown bugcheck: Bugcheck 7f. Parameters = 0x0 0x0 0x0 0x0.

Repair action: system restore
Result completed successfully

Note this is the results from 2 separate occations

I have tried System restore to an older date but it did not work

I have tried safe mode, did a dskchk with /f but didn't do anything

Unfortunately I have made no backup

Also, the windows came with the computer so I don't have any disks or anything

I am no expert,but the same thing happened to me with my laptop in October. I called my computer manufacturer's tech service and we went through most of the F8 options and none of them worked except for the options under recovery manager: I had a choice of full factory recovery or recovery with automatic data backup and I chose recovery with automatic data backup. Because I chose recovery with backup,I retained all of my files. I don't know if your computer has that option or not. But,if all else fells you may be able to do that.

There are probably other things you can do first. Other people with more knowledge than me might have other suggestions,I'm sure.

Good Luck!

Umm How do I get to that option? My computer has 3 safe modes and the rest are about debugging and stuff

Hi,

The manual should explain the recovery options- if you don't have one, search the Acer website for your exact model.

Often you press F11 or F12 to get the option to restore to factory condition.

They will probably have an online manual for download as pdf file.

Hope it helps

You press F8 button a bunch of times as soon as you turn on your computer. Keep pressing it over and over until you see the screen where it has Repair Your Computer highlighted,click enter. Then you should be taken to a sceen that says,keyboard layout,click next. Then you should be taken to another small screen where you select your user name,click next. Then after that,you should see a much larger screen that has system recovery options. At the very bottom of that screen,on my computer,it says recovery manager. If you have that,click on that and keep clicking next until you see a screen that may say full factory recovery or recovery with automatic data backup. I don't know if your computer will have recovery manager or not. Full factory recovery will wipe everything out and install a new copy of Windows Vista-don't choose that unless you want to lose all of your personal files. Choose the one that includes the word,backup.

Again,there are other options you may be able to try first. This would definitely be a last resort option.

Let me know if my instructions were clear or not. I'll try it on my computer again and write down exactly what I see in better detail and repost in case this wasn't clear enough. Your computer may be set up differently from mine. I have a Gateway laptop.

I hope this helps!
