Hope I'm not stepping on toes.
What is meant by your post #1?

I was using my computer suddenly power supply went,
----------

Falak when your had the power problem your bios could of changed due to the power surge.
If it was my computer I would set your motherboard bios back to default and go from their. Your motherboard manual will tell you how to do that.

Please note: I did NOT say update your bios.
Reset to default.

Power supply problems can also cause damage to other hardware in that computer.

Reading this should help.

I will go back to watching and get out of the way.

 

[benjy206]

Layback bear could you step in. Im on my phone and very busy at the moment. That is if you can

 

[Falak]

@Dear Benjy 206: there is no option"Last good Configuration" in advance boot menu.

 

[benjy206]

Please follow this link you are probably entering the wrong settings.

@Dear layBack Bear: I think you are right there is some hardware problem....i will tell you soon after reseting motherboard bios.

 

[benjy206]

Yes do that. Also be careful with what you touch on the motherboard. Touch the power supply to discharge, if you can use ESD strap. Do you need help on finding your Jumpers to reset the BIOS

@ Dear benjy:
1.In Safe mode Option...."Loading file windows" cant load all files and black screen appeared again.
2."Last known good Configuration" did not work

3."Windows Boot manager" results in
File:\boot\memtest.exe
Status: 0x000000f
Info: The Selected entry Could not be loaded because the application is missing or Corrupt.

 

[benjy206]

Oh your mbr is corrupt or missing what you need to do is follow this but you need the windows disk http://www.sevenforums.com/tutorials/681-startup-repair.html

 

[benjy206]

Or you could do this also with command prompt:


To run the Bootrec.exe tool, you must start Windows RE. To do this, follow these steps:
1. Put the Windows Vista or Windows 7 installation disc in the disc drive, and then start the computer.

2. Press a key when you are prompted. Select a language, a time, a currency, a keyboard or an input method, and then clickNext.

3. Click Repair your computer.

4. Click the operating system that you want to repair, and then click Next.

5. In the System Recovery Options dialog box, click Command Prompt.

6. Type Bootrec.exe, and then press ENTER.
