I do think it could damage other components because of the resarts, a resart unexpectidly is never a good thing that and the fact that I know your current psu is not of very good quality is why I recommend changing it before damage happens.
I hate recommending people spend thier hard earned cash without being absoultly sure it will fix thier problem but in this case with the video card you are running and that psu you will be doing yourself a favor either way

The modern computer power supply doesn't just supply power, it also send logic signals to the mother board, and some of those signals tell the mother board to reset. The intention with those signals is to protect the computer from data corruption, so that when power is lost the mother board will positivley reset before the CPU voltages drop too low.
The problem is that on some supplies these circuits are too sensitive, and send out too many reset signals, even when there is no good reason to reset.
There is no way to adjust these settings. If that's what the problem is, one of the cheaper ways to solve it is to replace the supply as Doby says.
A couple of questions
Did you build this computer yourself?
Has it always had simlar problems?
If the answer to both those questions is yes, then the power supply is a likely candidate.

PS None of the lights go out? Do you have one of those fancy cases with the clear plastic cutouts on the sides that lets you look at the neat LED's inside?

so i need to get one with 2 v rails?
No what you need is more amps on the 12v for your system 24a on the 12v would be good so get a name brand Antec, Enermax, thermaltake to name a few just read the specs and make sure the psu you pick is of atleast 400w and 24A on the 12v but remember most new psu's have 12v1 and 12v2 so you add these together to get the total amps.
Try newegg.com or zipzoomfly.com for pricing.
EMCguy gave you a good explination of a flaky psu and how it acts.

does the system go to a blue screen with fans and lights still on?
does the system go to a black screen with fan and lights still on?
does the system reboot windows.
Tell me this and then I will tell you about a program to run to test your hardware.

Prime will test the cpu, mobo,ram and psu. It does not test the video card or software/drivers.
Report back how long it runs till it stops or errors if it does, let it run for 6 hours if it will and keep a eye on your cpu temp for awhile and report that also.
If it runs prime for 6 hours then your hardware is solid and not the problem, this includes the power supply

My problem is as follows:
Computer reboots randomly, usually within 1 hour of booting it up. It restarts and the fans spin faster but the moniter does not pick up signal. The monitor also appears that it is connected (no floating RGB box asking to check video cables). To actually reboot the computer once this happens I have to turn it off and back on. The reboots continue this at a more frequent rate until I cant even reach the desktop. This sounds a lot like a heating problem, but i have never had a problem like this before and it isnt when the computer is running a game or some other memory/video card hog.
I don't know what to do. Help please. I will update when I install new drivers.
Also, my specs are as follows
Asus A7N8X motherboard
1.5 gig pc 2700 ram
WD 120 + 160 gig hard drives, partitioned into 40 gb sections
BFG 6800 Ultra OC AGP video card
Semi-new Thermaltake 480 watt PSU

Thats why I also suggested to run prime95 because that too will only error if its hardware related and not if its a driver issue.
Hope that helps you somewhat.
