Tnx to all your suggestion guys..
I already fix my PC now..

If it is OK,I will ask another question..

I also have a pentium 4 and my problem is every time I try boot my PC and when I already got in to the windows,my PC keeps on restarting.

I already format my PC and installed a new os. But the same problem occurs,I already used three sdram. Still,the problem is there..

I tried to change motherboard,I also used the same ram that I used before.. Same thing happen and I can't install a new os in my hard drive..

I don't know what to do.. Please help me guys..
