Hi, my friend was planning on upgrading his ram on his Sony VAIO desktop, so i opened it up to see it it was ddr and it it could suport high density. Well, it turned out, yes it was ddr and high density. I then put the stick back in, closed it up. My buddy went and tryed to turn it on and it turned on and the lights came on, but it doesnt boot. I opened it back up and checked the conections, but still nothing.

Please, if somebody can help me with this, it would be greatly enjoyed.

Thanx,
POD
