Hey guys, hope you can help me out with a prob i'm having (and it's annoying as hell). My PC overheated (60 C) a few weeks ago. Fans were clogged, so I cleaned it up nice and good and temp dropped to 49-53. Which is fine since I use a generic fan/heatsink. But since then I've been getting this video problem, anytime i try to play video, no matter what format (DVD, mpg, avi, online streaming videos), my PC will definitely hang, but you just don't know when. Kinda like the longer you play a video, the higher the chance of my PC hanging. It happens with some games too, I tried playing Divine Divinity (which relies heavily on DirectX), it hangs most of the time. I've formatted countless times, and it's still like this, so I think one of my hardware is screwed up a bit (from the overheating perhaps, or it's just its time). I was thinking maybe DirectX or DetonatorXP problem, tried changing versions, no help. BTW dxdiag sez nothing is wrong, except if I try to change the "music" port to something other than the default (first in the list). I've had this prob for quite a while now, coupla weeks, a little over a month, BUT yesterday I discovered that if I try to use internet phone, it hangs as well. So not just video anymore for god's sake. Also, when it hangs/freezes, there's always a high pitched sound, like someone flatlined. My setup: Hardware AMD Athlon 1.2 (overclocked 1.33) Soltek mobo (can't remember model, DDR333 compatible) 512MB DDR PC2100 MSI GeForce 4 Ti 4200 64MB SB Live! DE 5.1 skipping the irrelevant stuff... Driver side I've got all the latest drivers including: VIA Hyperion 4in1 451v DetonatorXP 56.72 Live! Driver Pack (updated, can't remember ver) and Direct X 9.0b Thing is, b4 this happened, I've been using these drivers and nothing like that has ever happened. That's why I'm thinking maybe it's hardware fault. Any ideas which piece of hardware is guilty..? What's a PC good for if you can't play any form of video (esp DVDs), and now not even internet phone? It's not just the phone problem, I mean now it's just not ONLY video it's audio as well! ARGGHH Any help would be great, thanx a lot!
