Hello, A problem today--
Start up software--OK
Voltage diagnostic--All OK
Blank Check--OK
Write--hangs at 0% forever.

Then, I cannot do anything else with program--I can't quit (must restart PC to quit), can't blank check again (hangs), even voltage diagnostic hangs.

I have burned hundreds of EPROMs, no problem, then this problem occurs today. I have made no changes to the PC, no new software or anything else (I only use this PC for burning EPROMS)

Please advise, Thank you.

It may caused one of the followings:

1. bad chip. Confirm your is a real good one.
2. bad USB connection. Check the USB cable, USB port. Change the USB cable.
3. bad pin contact
