My Asus T3000 always starts gliching after playing for at least a half hour. I have to reboot for it to stop. Also if I have had the wifi on is will do this, so I shut off Wifi and reboot.

disconnect the battery for half an hour and then reconnect.
if something electronic starts misbehaving always reboot it as a first step

Reset the device to factory, 90% of android issues are bad apps.
Settings>Privacy>Factory data Reset

Most likely is an intermittent solder connection opening up as set warms up.

Yes. You'll need a video downloader program (ex. DownloadHelper) to download the .FLV youtube video file itself. The T3000 can play older version .FLV files... most newer youtube videos will probably not work because they are the newer version. If you go to machspeed.com (trio's website) you can get a video to .AVI converter for one of their other players (nothing online for the T3000) if you convert the .FLV video to .AVI using one of MachSpeed's AVI converters (for a similar product) should allow the converted videos to play fine. I have the same model, T3000... Hope this helps - good luck!

change your graphics card or you may upgrade your card.

well let me tell you what to do your ps3 is about to fail and not turning at all this is the first problem then the second problem is that the ps3 will not turn on at all it will bip every time you will try to turn it on but there is a fix for this what have happen is that the GPU got to hot and now is not making a good contact with all the pin on the bottom of the GPU is sounds crazy you may say what this guy is talking about but believe me do something before it gets worse go to ebay and on the ebay home page enter the word ps3 reflow there you will see 2 guys that do this type of work because this is what you unit needs the GPU needs to be reflow and this will take care of this problem

Maybe trying a hard reset to factory settings?

Sounds like the drivers need an Update or reinstall.
No mention wheather or not your on battery or ac power pack when it drops out either so I am going to assume your on battery and its going flat.
If your on AC Power pack then its a driver issue,simple enogh to fix by a simple remove and reinstall

OR

go to

http://support.asus.com/download/download.aspx?SLanguage=en-us

use the auto find function for new users and this will install a Auto Find Navigation Tools on to your computer,
Let the tool find your motherboard and it will give you a list of the drivers available and Manuals as well

There is a NB Probe available for this model and it will tell you all about the devices and the operating temperatures of each device installed,ie,hard drives,fan speed and temperature,
memory installed ,cpu usage etc......

Very simple to use and its free thanks ASUS

Try uninstalling the drivers for the drive from the device manager and rebooting. Most of the time this is a simple driver glich. If it still doesn't recognize it, take it out and clean the connection, it could be a little dirt or corrosion build up.
