clean up the ram module

i did it ten times......but to no avail!

The best thing u can do to check the problem is this.....

Insert ur RAM on some other PC (make sure that da speed matches) & see whether it is detected....If it gets detected then nothings wrong with the RAM module...

Alternatively, get some other RAM module from a friends PC & try it on ur mobo (again make sure that the speed matches)......If it gets detected, then u can rule out that ur memory slot is working perfectly....

And unfortunately, if both these things fail......time to take it to da doc....

I had done this thing a couple of years back & was successful in detecting a faulty memory slot...

i found it it was a faulty chip(128mb),the slots are fine!
