I really must concur with the advice given by yeshuas higher up in the thread -- your computer is booting correctly when you power it on, so that the boot files are properly configured.
Therefore, the problem on your rig has to be a more fiddly one.
Daniel has suggested that your computer may be crashing during shutdown after you ask it to restart, which is possible -- if that were the case though, then you would see a variant boot screen where it would offer to start up in safe mode, or normally, or some other options, rather than getting black screen - unless of course your black screen is hiding that menu, which *can* happen.
I can think of a few other possibilities --
There may be a hard drive error, so that the restart data is corrupted on the drive, and Windows fails to load properly in that scenario ; if this is a desktop rig, you can try changing your IDE ribbon or SATA connector cable.
Another point is that upgrading from XP to Vista is not really recommendable, because some software for XP is not 100% fully compatible with Vista, even in cases where the software may basically work ; you can try running msconfig, then in the Startup tab, uncheck anything that is not absolutely necessary to have running on your computer. If this appears to fix your restart problem, then you should be able to use a little amateur detective work to find which software causes the trouble, by reactivating them in startup one by one.
The issue may be caused by actual hardware damage ; hopefully not, because if so, it will be difficult to guess which component might be damaged.
This could be a drivers issue, either hardware or software drivers, although frankly I'd doubt it ; but sometimes weird things can happen with imperfect drivers.
It may just be a Vista setup issue, and believe me -- Vista can *very* easily have setup problems, as it's by far the most difficult version of Windows to install correctly.
Just a longshot, but given that this sounds like a XP era machine that you've upgraded -- there are some old ATI graphics cards which can cause blackscreen issues during boot, such as the Radeon 9250 and similar ; if you have one of those cards, then you will either have to put up with the behaviour, or change the card.
The trouble I'm having here, to be honest, is that I'm not absolutely certain about the precise differences in Windows behaviour between rebooting and booting from power down -- although some data will remain in cache and likely in RAM during rebooting, and this data will be the cause of your black screen, whether the blackscreen is a pure software issue or if it is caused by hardware or hardware configuration issues.
In your shoes, I'd look at the cheapest theories first -- check to see if any drivers update or changing programs launched at startup in msconfig can help or not ; try and ensure that you have no Vista-incompatible software installed ; check your cable connections, and if possible change the cables ; see if a clean install of Vista helps or not (this will be time consuming, but time would be the only expense) (clean install rather than upgrade btw, because if the problem lies in the registry, upgrade will not fix it) ; and if the problem still persists, then you can start worrying about actual hardware failures, whether hard drive or GPU.
It is very difficult to pinpoint the problem in cases such as yours -- but I think we can be pretty sure that whatever it is, it is highly unlikely that it it's a problem with your booting configuration as such.
