Help! I could not turn dell desktop computer power up.

We have it for maybe three years. Anybody know how to fix.


I have lots of files in it. Have not made the copy yet. Hope it won't be the problems of hard drive.

thanks,

• 不能Ｐower on最可能就是Ｐower Ｓupply Ｕnit坏了，换一个试试看。 -希腊孤客- ♂ (0 bytes) () 05/03/2013 postreply 11:29:00

• 把硬盘取下来挂外置读读看，如果成备份再说。不成，那就硬盘坏了。 -喜欢豪宅- ♂ (0 bytes) () 05/03/2013 postreply 12:28:46
