i would get a stick of ram that is compatable with your rig....one stick....then read the manual to see which slot one ram stick goes...on mine its either the one closest to the cpu and the one futhest from the cpu.....if it stiil does start....ddp has said several times clear cmos....this is a jumper usally right next to battery...3 little pins with a jumper cap over two of them....move the cap and cover the pin thats open and the one next to it[center pin]1st pin should be open now]then let stay for a couple of seconds.now put back to the original...thats how you clear cmos if you didnt know.....try ram in other pc to see if it works first....if ps works and ram is good the fans will spin and lights will come on...no video could be card or ram....so much can happen....i hope i get this right....the capacitors are flat not coned,no prob right?...hope this helps....peace
A cheap and effective way is to buy a poer supply tester, you can find them for around $10. they plug into the atx plug on your psu and there is a switch on it, which allows you to turn on the psu and test it, without using anything in the system. also i would take each part out of the system, and swap it with a known-good replacement. Also, take a quick look at all the wires in the system and make sure none are short circuiting the psu.
Sorry if i have come to the wrong thread for this but i have made a custom built pc for the first time and i dont know how much power i need to power it. Because im only 15 and aint got no job i am getting slow on making it but i have the basic parts Intel Core i7 920 Gigabyte EX58-UD3R Motherboard OCZ Gold edition and 3 PC case fans if anyone could tell me how powerful the PSU needs to be that would be much appreciated
