Cannot install normal or delete almost any programs. When I want
to write any text I appears infinitely \\\\\\\\ (and even before I
enter windows password). Cannot run directly any program exe or com.
My HDD has 500 Gb, but windows sees lower. All programs that I
install "digital signature not available", and some .exe programs
disappear. I have installed many times windows 7 and I had
different errors, the latter being bllue screen 0x0000007b.
I tried to install Windows XP but could not be: Usbehci.sys corrupt.
I installed various antivirus,antispy, but nothing ...Sometimes windows no
longer starts and appears only a black screen and a beep, beep, beep...
I tried to format my HDD but chkdsk locks on to 50%, while all the
time when I run in DOS "directoy is not ready" ...
I ran GMER and MBR and I know fastfat sys, fltmgr. sys, Classpnp.sys.....
file is corrupted. What can I do??????
