antec truepower 550 & samsung syncmaster 955df?????

[Chacotako]

I recently bought a Antec TruePower 550 Watt ATX12V, I used it for about a week and my computer all of a sudden after I'd restart, it would just surge on for like 3 seconds then restart and repeat that over and over again. So it was like a constant surge on for 3 seconds then shut off and then surge again.

So I put in my old generic pos 420watt, and everything worked fine. I RMA'd the drive back to newegg and got my new one a few weeks later. I just got an opportunity to put it in today, everything was working great, I restarted so I could re-format and what do you know, it does it again. Meanwhile, it was just on for about 45 minutes no problem.

So my friend and I start to mess with things and it turns out, as long as my monitor cable isn't plugged into my videocard, everything works fine. I tried changing monitor power cables, no luck. I even tried an old monitor and everything worked wonderfully. It just seems to be this one monitor connector off of my Samsung Syncmaster 955DF? Does anyone have any idea on how to fix this?

That's a 19 inch pretty nice monitor and it works with the piece of crap psu. So what gives? this makes absolutely no sense to me at all. I can unplug the connector and it will fire up. ONLY when I plug the connector in, it will surge. Other monitors work, but those are old 13 and 15 inch monitors and who's gonna use those? Especially a gamer?

So now I'm guessing, it's not the psu and I wasted time RMAing in the first place but something with my monitor? anyhelp is HUGELY appreciated as this is VERY frustrating to me.

Thanks in advance

It's doubtful that this is important betcause everything has run flawlessly on my no-name pos 420watt psu for about 4 months now, but i'm running:

AMD 64 bit 3500+
1 gig corsair 3200 ram
Radeon x800 pro
Western Digital Raptor 37 gig 10,000 hd
plain 52x cd-rom and an old pos burner
can't remember the mobo off hand, if its important whatsoever i'll get it

thanks again

How many items are plugged into your power socket?

I have the same 19" monitor and it draws quite a bit of power.

The combination of 550W PSU and the 19" monitor might be too much for your power socket.

Try only having just the monitor and computer in the power socket, and leave everything else unplugged.

I don't even know if this will work, since I don't even know if this is how you set it up.
