this might belong to virus section aswell, but here i go:
I have asus k55v with preinstalled Windows 7 HP. I have made the mistake of not installing any anti-virus, because i knew i would eventually reinstall the system and upgrade it to windows 7 Ultimate, (yeah i really dont like the preinstalled programs from manufacturer)
last week the computer was getting slower: starting up was taking way too long, cca 10 minutes just to launch windows explorer/Chrome. However, yesterday the starting time exceeded 30 mins, and after i restarted my pc again, couldnt run any program at all.
I switched to safe-mode and moved my data to external harddrive. only the safe-mode WITHOUT network drivers worked (otherwise, there was exactly the same problem)
then, i wanted to reinstall the windows.
Here comes the fun part, the windows couldnt read the installation disk at all. I tried to read other DvD/CD (music CD) in safe mode, and there was no problem reading it. however, when i inserted any copy of windows nothing happened (even in safe mode).
in booting setings i selected DVD as my booting priority, and still, nothing happened, the system booted from 2nd option, like the dvd wasnt there.
I own several original copies (with watermarks etc) of windows, what i have tried:
windows 7 Ultimate 32
windows 7 Ultimate 64 two different DvDs
windows Vista Ultimate 32
windows Vista Ultimate 64
is it some sort of bug? or is my BIOS infected? because i have reinstalled this PC several times before and nothing like this happened.
i can add some pictures, if requested
thanks in advance
