Hi, ive recently had a problem with my computer. All of a suddent i was playing Starcraft 2 and decided to plug in my head phones and all of a sudden the game froze, i then replugged my speakers and the computer unfroze, then again i tried the headphones but the computer yet again froze...... After repluggin my speakers the computer remained frozen. I rebooted but my monitor wasnt receiving any signal so i assumed my G-Card had fecked up (Nvidia 8800 Ultra). My friend came over and plugged in his Nvidia GTX 280, it worked fine. So then we decided to try my card on his computer, and it actually worked......... This kinda lead me to think it was the motherboard was acting up (Asus Striker 2 Forumla). We played around a bit and noticed even though the screen wasnt receiving any signal it continued to boot up but it took nearly 10 mins to actually load up windows. And then the hard drive starts clicking rather loud. I phoned up Asus to see if they could confirm that it was a motherboard problem but some asshole hung up on me. Although he seemed to think it was my Graphics Card, which to me doesn't make much sense since it worked fine on my friends computer. I think im going to have to buy either a new Graphics card or Motherboard........But which one is causing the problem.... I hope someone out there can help out.
