I just clumsily pulled the main power cord from the battery/UPS, turning off the PC while it ran. Now it boots into Windows 7, and a few seconds later reboots. The first time it did so, it displayed a message “CPU overclocking failed”. I checked CPU setup and it’s at normal mode. Does it in safe mode, too. It doesn’t restart if in pre-windows mode, such as in a setup utility. No idea what went wrong, would appreciate advice on fixing it.
For a while, Windows wouldn’t start at all, “the boot selection failed because a required device is inaccessible”. Windows CD isn’t allowing a repair. Then Windows started again and is running for now.
The guy who built that computer for me talked me through turning off overclocking for sure, then it started to re-boot itself again. Unless I can get help in Nashville, I’ll have to drive about three hours to get it looked at…
Sounds like your BIOS settings got corrupted.
I would try booting into BIOS/CMOS (setup) and restore to default settings and save. Otherwise, try booting to your windows recovery/install CD and it should have a disk check/repair option, if I recall correctly.
I used ASUS BIOS setup to go with defaults, but that didn’t help. Is there another way to re-set BIOS?
Reboot and you will have a couple seconds to hit “del” or “F2” (I think it’s the del key on asus) which will take you directly into the bios. Follow the nav guide on the bottom of the page and you should find the default reset.
That produced no change.
Okay, reboot and hold down “F8” key, this should put you into the recovery console. Select repair computer and follow the prompts.
Believe it or not, the power supply can cause that. Try unplugging all of the USB connections except keyboard and mouse, and plugging the computer’s power cord directly into a wall socket instead of an extension cord or power strip. Power supplies are pretty cheap and fairly easy to replace.
Good point. Had it in my head for some reason that it was a laptop.
Original disk Win7 in hand?
Установочный диск в наличии? Там есть несколько опций восстановления системы. Мне кажется надо начать с восстановления загрузчика.
Boot of the win7 install DVD. Select “repair your computer” from the first screen. This will get you to the recovery environment. From there, try either “startup repair” or “system restore” to an earlier setpoint. You can also open the command prompt, and chkdsk the file system until it runs clean.
Repairs failed.
“repairs failed”, as in that didn’t work, or something in the recovery environment presented you with an error message? If the latter, what was the error?
Next step.. Get a Mac.
Oleg had a Mac.
After all of the PC trouble you have had you might be better off investing in a new one. Have it built by someone that will stand behind the work that they do. You should not be having issues like this.
I’m sure you have spent so much time on this PC that it is worth getting something much more reliable. Might be about the same price as some glass, but since it is a cornerstone of your digital work it it important.
And as always – love your pictures. You are blessed with light.
Rather than dump the entire thing, things to check in order:
* power supply voltages within 5% of what they should be. If they’re not, get out a phillips screw driver, remove the screws at the back of the case for the power supply (not on the fan grille..) and pull it out. Buy a new one and dispose of the old one. You want an OCZ or other “enthusiast” power supply. Higher wattage is better.
* right click on your boot drive, properties, tools, scan for errors. check both options. It may need to reboot to perform the checks, and they will take a while. If checks fail, back everything up and reinstall (not repair) Windows. Restore your personal files (not the whole drive) from the backup.
But I’d be willing to bet that those two cover the issues. Less likely items are damage to the CPU, motherboard or RAM. The first and last are easyto replace (though expensive) and the motherboard is less expensive, but a hassle due to screws.
All hardware items were individually tested and passed. On-board video card isn’t active, so I can’t run from it. The box is free-standing and have one big fan incoming and three outgoing.
I have an industrial size UPS on its own circuit on which it worked fine for a while. Power should be fine.
No USB devices besides the keyboard and mouse.
OK, back to the laptop. It just re-booted as it did before — not frozen screen but black screen and a reboot.
“I have an industrial size UPS on its own circuit on which it worked fine for a while. Power should be fine.”
Industrial size — what exactly? Not all UPSes are alike. An online UPS won’t produce as good or well regulated power as a dual conversion unit. But, they are quite a bit more money.
