It's a custom built, second hand mid-spec gaming PC (runs most games mid-high settings) everything is fine with it however upon replacing the PSU recently the DVD drives no longer work, they are powered but won't read, I'll take a look later to see if it's wired correctly.
Here's the spec:
Motherboard: Asus P5B
Processor: Intel Core2 Duo E6750 @ 2.66GHz
Memory: 2x 1GB DDR2 6400
Hard Drive: 2x 250GB SATA2 Seagate
Video Card: ATI Radeon HD 2600 Pro.
Sound Card: SoundMAX HD Audio
Operating System: XP Pro.
Any ideas or a rough price range I should be looking at?
