It sounds like possible bad sectors
by Feb 21, 2013 5:23AM PST

Get a repair disc and boot to the command prompt. Then issue this command: Chkdsk /f /r . This will check for bad sectors and attempt repair of them. Note that this can run for several hours depending on hard drive size. If you don't have a repair disc, you can make one on any Windows 7 system. Just click Start -> Control Panel -> Backup and Recovery -> Create a system repair disc. Insert a CD-R and in 2 minutes you'll have it.

Good luck.

If you can't boot from a repair disc
by wpgwpg Feb 21, 2013 10:37PM PST

You have a defective computer if you can't boot from a repair disc. Could be motherboard, could be DVD/CD drive, could be power supply. Take it to a service technician.

Good luck.

The HDD message is a bad sign.
by Forum moderator Feb 21, 2013 5:22AM PST

But try this. Power off, remove power and gently unplug and plug the SATA cables and power to the HDD back in at both ends of the SATA cable.

If that fails, replace the HDD and reinstall the OS. Put the old HDD into some USB case if you want to try to salvage your files.

the hdd is fine
by Jayerrr Feb 21, 2013 10:12PM PST

if i connect my hdd to an other PC, it works perfectly... if I try to install the OS on an other HDD, same thing...
I was thinking it may be the BIOS?

My motherboard: asrock z77 pro 3

Then the machine has a defect.
by r. proffitt Forum moderator Feb 22, 2013 12:12AM PST

It's quite the odd failure. Could be any one of the parts in the defective PC from bad parts to incorrect settings.

Think back to when it worked. What's new, what's changed and is there any question in anyone's mind about heatsink compound, fans or flaky video systems?

As it stands the PC looks to have the defect.

have no idea
by Jayerrr Feb 22, 2013 4:51AM PST

what is new: i formatted the HDD...

everything worked fine, perfectly

my setup:

i7 2600k
16gb RAM
nvidia gtx 680
corsair gs800 power supply
zalman z11 case
asrock z77 pro3
wd caviar green 1tb 7200rpm
dvd reader/burner

when i look at the temps in the bios, the cpu runs about 40 degrees and the gpu around 35.

Maybe that's the clue.
by r. proffitt Forum moderator Feb 22, 2013 4:57AM PST

If you format that HDD, you could trip up Windows and it's installer. Lesson? Never format a drive. Let the Windows installer off the DVD partition and format the drive during install. Start with a blank HDD.

Nice list but it appears you are not trying the usual. That is, you don't nee all the sticks of RAM to sniff out the issue. Also the issues with ram is legendary. I've had discussions before and the builders rarely can check if the memory settings match the specs of the ram. Most builders think if it plugs in, they are done.

Start out basic
by lacsr Feb 22, 2013 8:32PM PST

Remove all but one stick of RAM and set BIOS back to defaults. Make sure the DVD drive is set for first boot item. Disconnect everything but the monitor, keyboard, and mouse. Try again with the Windows 7 install disk.
