But the issue is all PCs are getting blue screens while working. Several times per day and all get the same windows stop error...

hi leo, Thanks for the support.. I'll reinstall one machine again, updates and check whether the stop error pops again. The Hardware i bought may not have manufacture defects because i separately bought them. Each machine i both has at least 1 month gap. Also 1st thing i did was to check with the vendor whether the mother- board, RAM, Processor are compatible with each other. Even i check their compatibility from the products sites. Is there any testing tools or software which i can use to check the compatibility? I'll comeback with new results.. Thanks again.. Tharaka
