Hey guys, As some of you know im very new to this forum. This question doenst really relate to overclocking but you all seem like very smart people and maybe one of you could provide a solution for me. I recently purchased parts to build myself a new PC. Got the last of it in yesterday afternoon and threw that bad boy together. Now.. im having some major problems with the damn thing. Im going to copy and paste an e-mail I sent to Asus (the manufacturer of my video card) and hopefully one of you guys can provide me with a solution. First I'll describe what happens. The computer runs fine until i run an app that uses the graphics card for more than standard stuff.. for example a game or something along those lines. My computer will freeze or reboot or get a blue screen (win xp style) listing the error and then you need to hard power down the system. Im running windows XP professional. Anyway, heres the e-mail : ***********Start****************** Hello, I recently purchased and put together a new computer. I chose your video card (asus v8460 ultra deluxe) to incorporate it into my system based on the wonderful features, benchmarks and software that comes with it. However, I'm having a problem with it. I already sent my motherboard manufacturer an e-mail describing the problem to see if they could help me out with this problem on their end. Rather than explaining it all again I am going to just copy and paste what I sent them. If you have any clue as to why this is happening or how to fix it I would greatly appreciate it. My motherboard is a gigabyte ga-7vrxp based on the via kt333 chipset. The software that is giving me the hardware diagnostic is SmartDoctor that was included with my video card. Thankyou, Jose Garibay E-mail to Gigabyte : Hello, just a couple days ago i purchased your gigabyte ga-7vrxp. I also purchased an Asus v8460 ultra deluxe geforce 4 ti 4600 geforce 4 video card. The problem i'm having is that my system is very unstable. I ran some diagnostic utilities that were supplied with my video card and it says that the motherboard isn't providing my agp card with the required 3.3 volts (might be more or less.. it didnt specify). It said to contact my motherboard manufacturer/video card manufacturer. So thats what brings me here. I will also be visiting Asus tech support to see if they can direct me to the solution of this problem. If you have any idea why this would be happening or how to fix it I would greatly appreciate it. The motherboard had a sticker on it that said it was geforce 4 compatable so it should work.

Any more questions just e-mail me. I hope we can figure this problem out soon. Again thankyou for your time and support with this issue. ***************END******************* Thanks, Asphix Ps. Thank you in advance for any help you guys can offer me. Oh and another thing... a 430 watt power supply (dual fan, 460 watt peak) same quality as an Enermax should be able to power all that hardware right? i have 6 case fans, only 5 of them hooked up right now and all the hardware you read up there.. as for cpu cooler i have a swiftech mx420 or whatever it is.. the newest one that costs like $70 USD with a vantec tornado fan.. the one thats like 82 psu or csu or whatever the term is for how much air it pushes.
