I just got a new Samsung "SyncMaster 730B" LCD monitor for Christmas with a DVI cable hookup.  I plugged it into my computer and had a little trouble getting it to connect by digital because it kept trying to go to analog. Once it was working, I tried to play Counter Strike Source and about 5 minutes into the game, my screen went black and my computer froze. I couldn't ctrl-alt-del out of anything so I hit the power button. I decided to let my computer sit for a while and restart it, but now it won't even connect to the new monitor.
I tried connecting my old CRT monitor to it and the same thing happened (its an analog connection). Got into the game, about 5 minutes later, screen went black and my computer froze.
I finally decided to look into my computer and see if I had any loose connections or if all my fans were working.. and I found out that one of the fans on my power supply wasn't running. I know I need to get a new power supply but I was also wondering if (1) does an LCD monitor with DVI require a bigger power supply? (2) What size power supply would be good for my computer with the current equipment I have in it? (3) Would the power supply be my ultimate problem or would that just be "the icing on the cake" so to speak?

Thank you for your time,
Lisa

What size PSU do u have in it now?

1. i do not believe so, as the monitor has its own power source independent of the computer.

2. at the least a 300W power supply. i would, however, recommend a 500W power supply, for it leaves room for expansion.

3. no guarantees, it is either your PSU or your graphics card. since you are getting a new PSU anyway, it would be wise to see if the new PSU fixed the problem before buying a new graphics card.
