Hi all, i need some majour help with my computer. Early this morning i decided to move some files i had on an old written dvd to my pc and i inserted the dvd into my drive and i got a pop up saying the dvd was a blank cd. So i went to my computer and my dvd ram drive was being labled as a cd drive so i tried a few more of my dvd that i have written files on and it comes up as a blank cd and i cannot access the files on it. it wont boot any of my written dvd either. Here is the puzzler, the drive recognises orginal dvd's like my games crysis and gears of war and my asus sriker 2 dvd and i can install and play from them dvd's and the drive boots and plays cds. its just seems to be dvd's that i have written. I have not had any problem using these dvds before with this drive so i have no idea what is wrong. The only thing that i could think was wrong that i recently upgraded the bios and never tested the drive with a copied dvd just orginals. So i rolled back to a previouse version of the bios and just to be safe i hit the "clear bios switch" on my mobo. And what happens? the computer does not boot. My lcd poster was stuck on the dect dram. So i knew there was something wrong with the ram. I pulled out my ram and tested them 1 by 1 and what do i find has happened? one of my ram sticks has some how stopped working for no reason. So i am sitting here with a messed up dvd drive that reads everything but dvd's that i have written on. And a messed ram stick that some how blows because i clear the cmos. I have got a funny feeling my board has shorted and ruiend my drive and ram. But everything else works fine , hdd, Graphics card, and cpu all work perfect. What has happened to my computer?
