What's going on Lenovo Gurus, 

My Name is Jamal, and my shop is an authorized lenovo reseller. We acquired a thinkcentre under the TAP program. Earlier this year and has windows 7 on in. Runs great. Well it did, until this morning when our HR person turned on the machine and just got the Lenovo splash screen with a message at the bottom saying. "press enter to interrupt startup?" and it just stays there. No keyboard lights or anything. I did some usual test (we are a PC repair shop) Ram HDD and CPU seem to be functional but it still will not get past that screen? Is there something I need to check? Please any ideas would help. This machines has our quick books on it.

Never mind. Lenovo's awesome onsite warranty is sending out a tech.

use the clr cmos jumper on your motherboard, and activate it by moving the jumper across then put it back after 30 secs. Also, make sure you have no usb drive plugged into the desktop when you start the machine.
