    Hello my windows (it was vista) was corrupted it just freeze on windows startup logo and i decide to reinstall windows (7) on laptop Compaq Presario CQ56 from USB stick.
    First time when i tried to boot windows from USB stick it just freeze on boot loop menu just "Q" logo appear cant access bios no F2 no ESC, no F10 nothing work. Then i decide to remove HDD and put on my other Toshiba laptop. I format all partition even system installed win 7 and all work just fine on this Toshiba, until i put the HDD back to Compaq CQ56.
    Now when i hit power button it just stuck on boot screen with this "Q" logo.( no usb components plugged in or external drive)
    I just tried to remove battery, power cord then turn laptop without battery.Tried this way to hold power button for at least 15sec with windows button + "B", replaced CMOS battery too. Replaced HDD few times, RAM.. CD drive.. nothing.
    When i remove HDD it just show me screen no hard drive detected, there i can access BIOS( F2,esc F10 F11 just work) but when drive is placed back it just stuck.
    I tried 2 other HDD on this Compaq Presario but when appear windows startup screen it shown for a sec blue screen and just restarted.
    Please help me how can i fix this?
