Get yourself a live CD with something like Ubuntu, boot from it, and copy any data you don't want to lose to a flash or external hard drive. Then restore to factory settings and re-install you software and data.
`
When you've gotten your system back like you want it, I urge you to get yourself an external hard drive and a good 3rd party backup program. You can set it up to do everything automagically at the time and frequency of your choice. 1 TB external hard drives are about $60 these days and a really good FREE backup program is the Easeus Todo Backup Free. That can save you a lot of time and frustration the next time something like this happens. Sooner or later it happens to all computers for one reason or another.
Good luck.
Hi all,
so, sudden issues running windows 7. Came home from work to a non working pc. Nanny and kids young kids likely using it during the day although they deny it of course.
When i try to boot windows 7 a screen with "ASUS express gate". There appear to be some options for access to the internet, photos, games...if i dont do anything then after a few seconds the screen changes to "p6x58d.". About 30s later this screen disappears and my computer appears to be attempting to boot windows 7 but then crashes to a blue screen with some note about checking my system for viruses and disconnecting any perioherals and restart your computer if this is the first time or contact your system administrator or manufacturer if this continues.
I've been able to F8 to get to the option to run in safe mode but when i try i get the same blue screen. Sometimes when i restart the computer i get to another place that runs "startup repair" but ultimately get a message that "system repair cannot repair this computer automatically." Ive tried system restore but there arent any restore points.
Briefly surfing around suggests that asus express gate is some sort of os directly attached to the motherboard. Any suggestions for me? Any details i can attempt to clarify? The adults don't download programs and the kids are all under 4 so its unlikely they downloaded anything. No perioherals or other intentional changes have been made since there werent any issues last.
Thanks in advance
