im using an acer monitor (x199w), and it was recently upgraded from a Compaq because we thought the monitor was causing the issue. however, were experiencing the same issue with this monitor as well. im running an ati raedon x1650 pro video card with 1.5gigs of ddr ram, and randomly during a game the monitor will go to sleep and i am forced to push the power button and restart the pc that way. it's been doing this for quite some time, and i tried all the monitor ports on the back of the pc and all of the same have the same problem (the monitor port not connected to the video card didn't show any video display at all). thanks EDIT: i'm going to try getting some better air flow into the card because i think an issue might be heat as well. list of things i've done.. switched the monitor. changed power settings to NEVER turn off monitor. updated drivers. tweaked settings towards performance in ati CCC. changed wow settings according to my own settings. still...
Just a couple questions that may lead somewhere... Does this only happen in games? Has your machine done this before in the past? Does it do this issue on a constant bases in WoW? WoW is not a heavy GPU game...try downloading Furmark ( http://majorgeeks.com/Furmark_d5984.html ) and running it for a couple of hours and see what happens. Did you PC come with that graphics card? If not your PSU may not have enough power to support that card. Ati's web page ( http://ati.amd.com/products/radeonx1650/radeonx1650proagp/specs.html ) lists nothing in regards to the 12v rail requirments. However, they mention 350W on the PSU. Im guessing you will need at least 20-24 amps. If you don't have that much to dedicate you will have problems. Can you still hear sounds when your monitor shuts off? Have you ever seen a BSOD? Just to clarify, did you increase or decrease the clock settings? What temps are you getting on the card? Since you have an expansion graphics card, output video will be defaulted to the card.
no, it was upgraded from the stock card to a Gforce 5500 GFX, then to the ATI card. nope, i can't hear anything. my monitor says "NO SIGNAL", never seen BSOD on this pc. i didn't touch that setting, i didn't even see it to be honest. i don't think it's overclocked at all either. right now it's reading 0degrees also, my psu is a Bestec, model ATX-250-122-REV.: D2. it says... OUTPUT +12V / 14A, -12V / 0.8A 250W MAX. theres some other info listed, if you need to know it to determine something just let me know.
try another psu with at least 350 watts. if still have old video card then see if problem happens to it too. try the radeon on another pc to see if problem follows or not.
Your power supply specs are fairly low to be running a Radeon x1650 Pro. 350 watts and a 12v rail with at least 20 amps is required. One of two things will happen when under powering a graphics card when running 3D applications (running the operating system is 2D and will not tax the GPU). Vista is the exception, but I am assuming you are using XP or 2000 based off the PC specs. During gameplay the machine will shut down/restart or cut the video off. You have a couple options at this point depending on your computer. Are you using the same Compaq you mentioned? Some of the older HP/Compaq computers used a proprietary PSU. Often times they are physically smaller (about half the size in length). These PSUs generally give very low power outputs. I have replaced these PSUs with OEM replacements and have stuffed a full size PSU in these cases. Getting an OEM replacement PSU will not meet the specs that you will want for the ATI card. A full size replacement PSU will sometimes fit, although only three of the four screw holes will be used and some cable management will be necessary. A PSU replacement is easily justified to power a graphics card on older machines in my opinion. Even if you do replace the computer in the future you will have a spare PSU handy. Not a bad idea if you live in an area that has power problems. I live in Oklahoma and its very common to see power supplies go. Or you can just throw the FX5500 back in if you only plan on playing WoW. Its all up to you, hope this helps
sorry to bump this old thread but i am still having the issue after upgrading my psu to a Dynex 400-watt one. just wondering but on the back there is a red thing that i can switch between 115 VAC, and 230 VAC. i don't know what it is, could someone explain if switching to 230 VAC would change anything?
ah i see. i've been reading other issues like this around the internet and if theirs one thing i have in common it's a lot of the time people are playing music. i always have itunes on when i play wow, im gonna give it a go without the music and see how it goes.
even without music it's still doing this. i'm narrowing it down to an overheating issue because the video card is hot to the touch when it shuts down. I've turned the psu upside down so the fan points downward, hopefully that will help.
the X- series are hot mofo i had a x1950 you could cook an egg on but not so much as a hitch in performance. what worry's me is a reading of 0/C its not unknown for these cards to have a stuck temperature reading and the new Ati drivers or the newest for those series are really picky about the temp readings. try these modified drivers http://downloads.guru3d.com/Radeon-Omega-Drivers-4.8.442-download-1817.html if that doesn't work try turning off all Power Saving options on the card.
