I've tried it all, uninstalling programs, terminating processes, reinstalling windows 7 and disabling devices. I've learned that disabling usb devices can really mess up your computer to where you can't use the usb ports anymore and the disable and enable disappear in the menu. Yes, I've tried reinstalling and uninstalling the drivers for them(and everything else for that matter in hopes to fix the DPC Latency issue). Thankfully a restore to an earlier point worked and the usb port now works again but I can't disable it now still though(not that I would want to now that I know what happens).
Acer really has me boiling. After all the trouble of packing up the computer and sending it to them and when I get it back the only thing they did was test it? I think it's their problem now (not windows 7). There is definitely something wrong with how they built this computer. It's an Aspire M3802 desktop. I spent 700 bucks on this darn thing a couple months ago just so I could enjoy music, videos and the occasional game and this can do none of it well because of this stupid dpc latency problem. Here's how it looks after about an hour of use just surfing the interweb with firefox or listening to music. When I first start up it hovers around the 200 to 450 mark usually but it gets worse. Any other ideas? should I just file a complaint with the BBB? I guess I will have to keep this junky machine because no one will take it back or fix it. I could just use my laptop if all I wanted to do was microsoft word and web surfing. Didn't need to buy this machine if I knew that's all I could do with it.
