System specs:
i7 960 3.2Ghz
24GB ram
Asus mobo (don't remember model number)
850W corsair PSU


So I had a radeon 5870 1GB in for 4.5 years, it worked great. Recently Ive been trying my hand in youtube, so I've been using windows movie maker for editing etc.. and no problems, it loads fine renders fine etc...


So today I got my Asus 780ti in, and I installed it. installed the nVidia drivers, UNINSTALLED the old AMD catalyst control center and the old ATI drivers etc..

But my computer seems really slow with certain things now, like opening files etc..
my biggest complain/thing I noticed, is windows movie maker is super glitchy now. Like I'll have several differ clips loaded into the timeline, and it freezes and gutters when I try to move the "time marker" around. It even crashed once.


So as any good computer guy did, I checked the internet, couple of ideas: PSU isn't big enough. Well... it should be (I would think) its a 850W. The cards specs say it takes 375W so that leaves 475W for the rest of the system.

2nd idea is: that I mashed a sata cable, well I don't THINK I did.. but I'm doing a HDD speed test right now. here is a result of my C:/ drive




here is a link to the new card

Any ideas?

It should say PCI 12v. I'm not positive on that PSU. You might need to look at the manual for your PSU, but I'd think if you have everything in place and that's the available PCI power connector that it's good. Don't take that as gospel though.

Unfortunately I don't know what the numbers mean on the HDD test, I mean I get what they are... but I don't know what "ideal" is. Its a samsung F3 7200RPM drive.

...so maybe I f'd something up. :S

Uninstall all the drivers using Display driver uninstaller. Do both AMD and NVidia. Then after completion and reboot reinstall your NVidia card drivers. Make sure to get the drivers from either your card manufacturer or the NVidia website as they probably have drivers that have been updated since the driver disk that came with the card was made. Don't install a lower version and then upgrade them, get the most recent version and install that after a clean slate with the DDU.

done and done, booted into safe mode, used the DDU to uninstall all video drivers. then restarted, downloaded latest 780ti drivers from nVidias site.

and it apears to be a little faster... but windows movie maker is still glitching as bad as ever. I go to move my time marker on my timeline, and it takes 10-15 seconds for the video marker to move and to start playing..

I know I'm starting to sound like a broken record around Tom's with the same recommendations over and over, but hey, you have to cover the obvious and basic failures first. This is known. So I would next run Seatools for windows to test the hard drive:

Run Memtest86 to eliminate RAM modules as the problem:

Just out of curiosity, what is the model number of your corsair PSU?

What version and bit level is your Windows OS?

Are there any remarked devices (Symbol next to them) in the control panel device manager?

Is your rig plugged into a power strip or UPS? If so, plug it directly into the wall. Double check all your internal cable connections and make certain the card is completely seated and locked in place and all it's power connectors are firmly seated.

Visually verify that the GPU, CPU, PSU and case fans are all operating at normal speeds. Run HWinfo or a similar monitoring utility to verify there is not a thermal condition causing anything to throttle itself.

Try resetting the BIOS to default or optimal settings.

Last but not least, smoke a joint, take a pill or have a few shots, whatever is necessary to not go bonkers until this is sorted out. I'm sure we'll solve it sooner if not later.

I'm running Windows 7 64bit
I did check the fans last night, they were all moving at what appeared to be the correct speed. I also double checked my sata cables, they looked secure and not squashed.

the rest I'll have to test when I get home from work tonight.

Thanks for the help.
