My computer shuts down and has to be rebooted.
Programs running in usermode (like bitcoin) can not
directly cause system crashes[1]. If bitcoin encounters an error, the most you'll see is "bitcoin has stopped working", "assertion failed", or similar dialog box. Nothing else will close except for the faulty program and any dependencies. Usermode applications can however, cause crashes in poorly written drivers or through hardware overheating. Please ensure your system is up to date (windows updates), your drivers are up to date (especially chipset and third party RAID/SATA/SCSI controllers), and your system is not overheating.

Modern multi-tasking operating systems, such as Windows NT, Linux, or Mac OS X usually remain unharmed when an application program crashes.
I don't know if what you say is true or not. My system and drivers are all up to date and the bitcoin-qt is now working. I will explain.
Each time I started the bitcoin wallet it would run a few minutes before the computer turned itself off. during those few minutes, some of the block chain would get synchronized. So I started letting the wallet run and sync up until the computer crashed. Then I would restart the computer and let the wallet run again until the computer crashed again., (I know, not good for the system, but I didn't know what else to do) Eventually, the block chain got to within a couple thousand blocks of being fully synchronized. When that happened, the computer stopped crashing. Now my updated wallet is fully synchronized and there is no problem., So, like I said, I don't know if what you are saying is correct or not, all I know is that now that the wallet is synchronized with the network, my computer no longer crashes. And the only time it has ever crashed is while the wallet was trying to get synchronized.
