You have answered your own question... be restarting every two days you are cleaning and clearing your systems ram memory, history,,,etc,,,
Sounds like you have a lot of stuff running that isn't necessary..ALWAYS clear your history,,, its would be good to shut down every night and restart fresh everyday...

4, 8 track or Cassette tape?

the easiest solution could be to totally shut down your computer. let it reset itself, and power it back up again. If that does not seem to help, then I would clear the cache on your PC. I would also run a scan - see if there are errors.

Do you have alot of games on your PC? Do you download anything free that is offered? Many times that slows a PC way down.

Get a laser lens cleaner and run it. If that doesn't fix it, it's done. They're cheap players, and don't last that long.

Please check to see if the tape is running. It is possible that the tape was running dry and created the sqeak with a static noise over the head. the belt would have failed then and stopped the tape movement. hence without the transport your song is not played. So please check this out. Otherwise it is important to clean the head and check if your amplifier is working. test for voltage and audio tone. if not confirmif the audio amp is faulty and replace. Hope this helps. Good day

If this is the WMD6C then it is servo locked and can be fine tuned with the pitch control on the back of the unit just turn the switch to on then adjust to preferred speed.

you can only purchase a battery for your vehicle. the only thing a bigger battery will do is drain slower. You might think about putting in an on/off switch on the amp so you can shut the amp off when you are not using it.

try installing a inline noise filter in the hot wire running to your tape player, you can get one at radio shack.

Cassette players usually have a little rubber band that connects the motor to the spindles. If everything else is fine, I would suggest seeing if it slipped off somehow (or got cracked and snapped)
