[very]

Hi guys, new to forums and have a problem I hope you can help with.

I was running 2x 5830's on a P55A-UD4P (Gigabyte) mobo and decided to order 2 more 5830's and couple of 1x > 16x adapters to use the two x1 slots. So everything got here and I tried adding the new cards using dummy plugs - the system would fire up, but could not get a video signal. With 3 cards the same thing happened. So I decided to go back to just 2x cards to see if it would get a signal.. it did, but now everything is really messed up. Everything is very slow to load, anti-virus won't load at all, internet only connects for a second, then stops.. just a big mess really.

Any reason the 1x slots would not handle these cards and any idea why it messed my computer so badly??

I don't know as much about this stuff as you guys do, so any help is appreciated beyond comprehension. 

Thanks!
