You may have already done this, but remember many laptops require that you remove the battery for about 30 sec. as well as disconnect the AC power to reset them. Always try this when everything appears completely dead.
First check the settings under Sound Settings of the Realtek HD sound Manager. If everything looks ok and it works with external microphone, then the problem could be Hardware problem which won't be fixed unless the motherboard is replaced.
In the meantime, I would also suggest you to uninstall and re-install the sound driver. By the way, what's the operating system installed on your laptop?.. Hope this helps.
if ur dvd drive is working, try this. go to ur bios and then the boot section, then keep ur dvd/cd drive in first priority then save and exit. shal work. its easier to reboot OS win7 with pendrive. download win7 USB download tool. install it, run the tool and proceed as it asks.
The trick is to figure out what is the problem or better where it happened in the boot process. Safe mode by passes most drivers and such that are autoloaded so you know the basic windows setup is correct and working as you can get into safemode.
There are three things to try and one should tell you waht the problem is. At that point you can uninstall it or reinstall it to clear up the problem. If you had a virus the problem may be it changed a file or setting so knowing which one helps figuring out what to look at. Anyway your three choices here are watching the boot process to see how far it goes. This is crude and won;t really tell much. Read the bootlog.txt file after the next boot failure (located in root of C) and it will tell you up to the last good thing loaded and sometimes the bad one. For example it may say something like boot.dll loaded succesfully then the next line will be boot2 load attempt and thats the one that is the problem. The third thing is to run Dr watson and look at its reports to see what its wrong.
Most shops will just blow out windows and install over as it isn't worth trying to fix the install for them. You can easly spend several hours or more to maybe find the problem. You can try running repair console or repair on the setup cd to fix the problem. That will just fix any files in windows that are off or changed. It works but sometimes the problem is a aftermarket driver that it won;t touch.
