Ok i really really need help with this, i dunno if this is a OS problem but seems like it. I was using my computer and then i accidentally pressed the "Hibernate" button on my keyboard and so yea my computer went into hibernate mode but i pressed the button while i was loading up a game it was just CoD4. Iunno if it was it put too much pressure on my cpu or somethin which i dont think so cause it's a dual core 2.4ghz with 1.5gb ram and stuff.

But ANYWAYS, after i started back up the computer and logged back into my user and stuff, everything seemed fine at that point, but then the desktop started freezing up and i couldnt log into a game or anythin or i kinda forced logged off myself and relogged in through using the task manager and clicking "Logout user". Somehow apparently doing that messed up my computer and it restarted itself but right b4 that a blue screen flashed realquick, couldnt EVEN see what it said. After it started back up it took REALLY long to login after i entered my password and stuff for my user profile. The startup then didnt took a long time like a few minutes, finally when icons started appearing my desktop's taskbar and everything else never appeared it was just my wallpaper and icons.

Now i cant even click onthe icons to drag them around at all and when i look into the processes of my task manager, it looks like alot of the SV_ghost processes and stuff were missing. I tried doing a system restore but apparently i couldnt cause i cant even access the startup menu. My search wont work either, all that pops up is that yellow microsoft dog but like nothing else, no where to type anything. The help center wont work when i press it in my control panel, the User button in the control panel has nothin in it when i open it. Seems like alot of processes got messed up when i did that logout thing. Ive never seen this problem happen b4 so if anyone has any experience on how to fix this please share it. I cant even open up any of the outside programs that ive downloaded or even internet explorer (using another computer atm)

If you have your windows cd/dvd, I would recommend booting off of that and running chkdsk.  This will often solve problems with the OS.Good advice.
I'd also go to Control Panel/System/Advanced and turn off/uncheck "auto re-start on errors"...this will then produce the BSOD next time.
Write down the error message INCLUDING the gibberish and post it here...
The info will provide CLUES as to what is happening.
You can also do this: Start/Run type in sfc /scannow and hit Enter...again have your Windows CD handy as it will ask for it...
Let it run to completion...remove the CD and re-boot.also very good advice  ok i started that up and all but i dont know what to do next. Im in the command PROMPT for the system restore using the windows CD but dont know what to do next. It had me choose the C directory so i did andthen entered my admin pass but now it's at C:/Windows> what do i do next?ok i managed to do a system restore to a point a few days ago but stilldoesnt work. everything is loading slowly and many things are unusable still. and still not taskbar and alot of the functions like dragging icons and accessing programs are all still messed up At the  C:/Windows> prompt type in cd\ and press enter. You will now see a standard C prompt. Type in chkdsk and press enter.
