Have you tried safe mode? that would be F8 during startup

(it loads default drivers and default graphics)

the screen doesnt show so i can't run it on safe mode

Have you tried?
Can you get into the bios?
Is the cmos/ bootup screen showing?
Since it is a desktop....can you try another monitor? to eliminate the monitor.

the bootup screen is not showing... i tried it on another monitor already and its not monitor. nothing shows up on the screen at all

You need to do some investigative work.
The no boot....no post...no video....can be a bad PSU, mainboard, memory, videocard, or processor.

I know you removed and played with the memory. Make sure you are grounded when touching any components.
Try 1 ram stick at a time.

Do you have a video card or is this on board video?
If using a card, try the on board (if available)

We can test the ram to see if its bad.

Broni's Instructions:


If you have more than one RAM module installed, try starting computer with one RAM stick at a time.

NOTE Keep in mind, the manual check listed above is always superior to the software check, listed below. DO NOT proceed with memtest, if you can go with option A

B. If you have only one RAM stick installed...
...run memtest...

1. Download - Pre-Compiled Bootable ISO (.zip)
2. Unzip downloaded memtest86+-2.11.iso.zip file.
3. Inside, you'll find memtest86+-2.11.iso file.
4. Download, and install ImgBurn: http://www.imgburn.com/
5. Insert blank CD into your CD drive.
6. Open ImgBurn, and click on Write image file to disc
7. Click on Browse for a file... icon:



8. Locate memtest86+-2.11.iso file, and click Open button.
9. Click on ImgBurn green arrow to start burning bootable memtest86 CD:



10. Once the CD is created, boot from it, and memtest will automatically start to run.

The running program will look something like this depending on the size and number of ram modules installed:




It's recommended to run 5-6 passes. Each pass contains very same 8 tests.

This will show the progress of the test. It can take a while. Be patient, or leave it running overnight.



The following image is the test results area:



The most important item here is the “errors” line. If you see ANY errors, even one, most likely, you have bad RAM.
