Hello and good mornin,well I ran the crap out of the PC after the new PSU install,let it run all night,have been on it for a bit this morning and no shut down,so I think that problem has been solved,But it would appear I have a new issue,everything is working excellent except burning DVDs,my burn time has slowed to a crawl,it used to take only about 7 or 8 minutes to back a movie up too DVD,now it takes over 30 minutes,I have tried a new IDE cable,messed around with burn speeds in properties and double checked jumper settings,still slow,The software I am using says the burn is at 16x,but no way.Is there something I can check in bios?Maybe this has something to do with the atapi errors I been getting?I give you many thanks for helping with my shut down issue,and I thank you in advance for any help on this new issue,thanks again.......Krazed.
