If it beeps (which it should) means that some device did not pass post. Find your motherboard online and look up the beep codes. This should help you to discover the problem. I hope this helps!

Error 0175


A bad CRC1 is a failed motherboard component, that generally has to do with the bios programming. Unfortunately, motherboard replacement is your only option.

CRC1 0175 Error


This error is typical of a problem with the system board.
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-4K2MCU

I've only seen this error appear on IBM thinkpads. Your EEPROM with the following steps.
You can try this to test the EEPROM
1.unplug AC,battery, HDD and and your cd/dvd rom drive.
2.press power button,last more than 10 seconds
3.plug battery and AC power
4.power on
5.when see the IBM logo,press F1 button immediately.

If the same error pops up, try it a few more times. If the error keeps displaying then it is the motherboard
