win 7 64 bit. desktop pc will not boot up go's to windows logo then freezes with black screen just showing mouse pointer.If i format and reload windows it is ok all day i can reboot as required but after turning off for the night the next day it will not boot and have to format again. any ideas please. This is driving me mad. Have put bios to default and no different.No new software or hardware added.
Are you sure you meant in (1) format and reinstall? If you do mean a full reinstall from the W7 disk, you must be totally fed up, and you can't even reach safe mode.
It may clear the matter for others who may also have the answer, but try and describe somehow exactly what you have done. The stalled blank black screen with cursor after the initial logo, implies obviously that Windows can't load.
Did you mean system restore instead of reinstall. Maybe your DVD drive is faulty if you confirm the the computer cannot load from that drive.
Finally got it to boot from disc and done a system restore and working ok nowjust hope it works after it as been off for a day. It is asus m/b p7p55d i5 650 and 9800gtx+ graphics 4gb ddr3 ram. I did do a full reinstall last time to get it running.I did also try another dvd drive and no difference.But as stated is running ok for now and reboots ok will switch off tonight and see what happens tomorrow. thanks for your help everyone much appreciated
