A clock interrupt was not received on the secondary processor

This should do it

I used it. It told me that process completed successfully but windows update still doesnt work

Hmm im getting BSOD's more frequently again

Have you done the memtest !!

I did 8 passes and it found me over 5 000 000 errors

Well there is you answer for the BSOD...

Replace it

So is it the rams?

doesn't 5 000 000 errors mean anything ???

Now im having different problem since i took out my ram stick. The PC turns on, the fans are working, the CR-RM is working but the monitor, the mouse and the keyboard are getting NO SIGNAL. And it doesnt matter if my ram are in or out. I checked my ram stick in my friend pc and they work. Do you think its motherboard?

How did you do the memtest ??

Did you follow the tutorial.... you need to test each ram in each slot for 6 to 8 passes... thats the only way to confirm if the slots or the RAM sticks are at fault
