I did all I can.

Ok so 3 days ago my main desktop computer randomly shut down while I was surfing the web.
So I turn it back on and after the loading screen appears (Running Vista BTW) it's supposed to go to the log in screen right? Well no it just stays a black screen with the mouse in the center (the mouse works though).
I tried loading it up in safe mode but the same thing happens. I ran disk checks, a diagnostics test and boot sector checks and it said everything was fine, except for the part that it said to verify my hard drive which I can only do if I log in and run the program. (RAID issue) well anyways I thought maybe my computer needs to cool down for a couple of days. Well anyways today I turn it on and the Dell loading screen pops up. The loading bar starts to fill up but then it just stops right before the end and my hard drive or computer or whatever starts making a high pitched beeping sound over and over. It doesn't stop until I turn my computer off. Now it won't even go to the microsoft loading page but instead stays on the Dell loading screen before that.

Now I think it has to do with Windows trying to load the OS from another source than the actual location, how it changed I don't know. I tried searching up answers on google but all I came up with was load it in safe mode and try fixing the problems there which I can't do. Or unplugging your printer and try turning it on when I did and it still didn't work.

Here are my specs.

OS: Windows Vista SP1 (Upgraded from XP SP2 if that is needed)
Processor speed: 3.22 GHz
RAM: 2 GB
Hard Drive Space: 144 GB (2 hard drives, 112 GB main and 32 GB backup)
Graphics card: Intel Family Chipset (dunno the numbers since my computer won't work...)

Please help me if you can. I can't even use the F8 or F12 functions anymore because it won't go past the first screen... so I can run diagnostics tests, load it in safe mode etc...

I'm desprate I don't want to have to reinstall the OS back to XP then install all the updates then install the Vista Upgrade then install all the Vista updates again...

The beeping might mean several things, but mostly it might indicate a hardware failure (CPU or RAM). Other than that, have you checked Google to see if somebody else has had the same issue?

[supersniper]

I checked about the black screen issue and everyone said they fixed it by going into safe mode and doing things which I couldn't do at the time. So I went try it today and the new error with the beeping came. I haven't searched that yet I thought I'd ask you guys here first since a lot of you are VERY familiar with computers.

Looking at the list, it appears you have a short, a loose card, or no power. <_<

Or alternatively a CPU overheat, that's happened to me so many fucking times I can't count >_>

HOLD UP!

I just turned it on to see what beeps I had and it was continuous so I shut it off, then I turned it back on and it worked. there were no beeps. Now it passed the Microsoft loading screen but it's on a black screen with the mouse again... this time it didn't go to the log in screen...

Then would not a couple days cool it down, if not a couple hours?

[supersniper]

Well it's turning on again. I tried to load it up in safe mode but still that stupid black screen with the mouse appears after it loads the necessary files for safe mode. I think maybe there is a problem with the CPU showing the username log in screen. Is there a way to bypass log in and just go straight to the desktop...
I'm so confused as to why SAFE mode isn't working either...

If the heatsink is broken or detached or if the thermal paste has any air pockets in it (as a result of the heatsink being detached from the cpu once without new thermal place being applied) then it's going to overheat very quickly, even if it's already cooled down from previous use.

Well, obviously. I assume that your CPU Heatsink is not broken and Thermal paste is evenly spread. Otherwise, you're just looking for trouble and are stupid for expecting to run a computer without both of those things functioning correctly.

Could it be the RRoD of computers without the visual display? Oh wait, that's the blue screen of death.... Sucks though, my computer just shut down randomly and restarted while I was talking to someone. Pissed me off too.

When I couldn't get to the login screen, I put in my windows CD and did the fixmbr and fixboot thing. It worked after that.

How many sticks of memory do you physically have in your computer?

If you have more than one, remove them one by one (then 2 by 2 or 3 by 3) and/or reseat them all. In addition to CPU issues, you could have a bad ir incorrectly seated stick of memory.
