I upgraded about 12 Dell Optiplex 740 (added 4GB RAM (Cruicial), put in new WD Caviar Black 500 GB hard drive (WD5002AALX) and installed Win 7 Pro 64).
On 3 of the machines Windows freezes randomly anywhere from 2-6 times a day. There is no pattern and I haven't been able to figure out what causes the problem. I changed the RAM and used a different brand hard drive but no luck.
Anybody experiencing the same issue? Found a cure? Or does anybody have an idea what I can do to fix the problem?
Any help is greatly appreciated!
