Need help with an issue....... I just built an I7 920 rig for a mate of mine. Specs below. I have installed XP pro 64bit. The thing is fast as hell until you try burning a dvd with nero. Then everything goes to custard. If I try to open an app while burning, firefox (just an example) it takes approx 20 seconds to open up and about 6 seconds if opened previously. It also stutters badly when trying to play video with media player etc... Asus PT6se I7 920 6gb corsair 1333mhz 30GB OCZ Vertex SSD 2 x 640gb WD Blacks HD4550 512mb GFX card Antec 430watt psu. Zigmatec S1283 cpu cooler LG 20x Sata DVD drive I have the OS on the SSD with apps as well. All up approx 13gb used. I figured it might be the SSD drive so I installed a quick Ubuntu 9.04 on one of the 640 WD's in there and it works fine but video still stutters and it seems to slow down a fair bit when opening pics etc.. I haven't tried burning DVD in Ubuntu yet. I will have machine back on monday. Just trying to get some ideas. All drivers loaded and up to date. Latest bios. Good temps. all stock bios settings. OCZ Vertex is the faster model SSD.
