When you switched to Windows 7 did you install a codec pack like USSR or K-lite? If your PC freezes only on video opening i can't see what else may cause it. Download a latest codec pack and see what happens, I really doubt it is antivirus related.
Heh.Please dont tell me you are actually using XDDM drivers If you are.Case closed - Install WDDM 1.1 drivers
Checked dxdiag and i have a WDDM 1.1 driver.. I can try to reinstall the codec pack. Also could you explain further bangbang? You had the same exact issue that sometimes when you started a video it would freeze and the only way to fix it was force reboot?? How does a loader affect that? EDIT: Note it happened again :-(
Funny you should say that Lomai! I had a very similar situation. I also have a i7-920, 6gigs of memory and a 1TB hard-drive, and gtx 260 graphics card. Its all being run by a CORSAIR CMPSU-550VX 550W PSU. Originally I had a 500w Antec Earthwatts with the same setup.. I was told that would be enough too.. I didnt really have any problems with it except for when I was gaming sometimes the PC would shutdown randomly and reboot. I got the 550W corsair and haven't had that happen during gaming, Do you think it's possible that id need yet a bigger PSU to avoid these problems? I really doubt I'd need more than 550W, and the bigger ones don't really fit in my dell case. Also could you tell me how you narrowed it down? I mean with the 550W i get no problems even during intense gaming. I havent tried any games on 7 though. Thanks for the info
So I removed CCCP and so far it hasnt happened.. Some more info about my above post would be appreciated.
A bad power supply certainly could be causing instability. An important thing to remember is not just to go by the stated wattage. Virtually all PSU manufacturers give a wattage rating based on an operating tempurature around 22 degrees Celcius (as I recall the actual figure). Of course no one operates their machine nearly this cold, and the actual wattage delivered drops as the temp rise. So what you THINK is delivering 500W may only be putting out 350W at its real operating temp. It's also worthwhile to keep in mind that the PSU is one of the more likely items to go in a system as it's the only one to deal with raw house current, and getting a lemon of a PSU is not at all impossible. If you have ANY doubts about the PSU, you might be advised to get another one with higher wattage, swap it out, and see if that clears up the problem. The worst thing possible is for the PSU to just die on you unexpectedly. I've seen that happen many times, ranging from no other damage (yay) to the PSU sending a nice big spike of hard current down the line as it goes killing EVERYTHING in the machine (major boo) to anywhere in between. Of course that is the one reason I never buy Dell desktops. They just LOVE to build their stuff so it requires highly priced proprietary stuff to fix, moreso than anyone else I've ever seen. A white box machine you built yourself is so much easier to deal with in the end.
Hi Topdnbass, Sorry for taking so long to respond. Trial and error and reading up on the net re finding out the power issues. All I can say is since changing power supplies, I no longer have any of the issues that I had previously. I've changed my config to include two R4890's in crossfire, additonal 1TB HDD and also running the technical preview of W7 (x64)- so far everything has been smooth including games. Photoshop really flies. Either way I think your existing PS should cater for your current config provided you are not loading too many intensive apps at any one time. Reason I went for the 1000W PS was to allow for additional overheads (juice) that the system would require. Hope this helps
From now on i will only believe you and noone else since they are always incorrect about everything lol
