Computer freezes at client house but works seamless on my workbench!
OK, I am having a small nightmare with this Dell computer of a client. It's an old PC (6 years) with a Pentium dual core CPU and 4 GB of RAM. His computer was freezing and getting BSOD and then started to say that his Windows wasn't genuine (it wasn't indeed). Also it has warned him several times about updating because it was a very earlier version with no SP.
Then the client asked me to perform a fresh install, so I put on Win 7 Ultimate BR SP1, Office 2007, AV, FW, K-Lite and Java. Just in case I ran checkdisk and Memtest86 in two exhaustive test sessions (total of 16 hours) and no RAM problem or bad sectors found.
After the install it is too slow for my taste but it is expected for such an old computer and also the client installed a proprietary internet browser for his Internet banking that uses a stupid module that bites a lot of CPU and RAM at the startup but after a few minutes it calms down and the computer becomes usable.
OK, but this is not the problem. The issue is that the computer works smoothly on my workbench but whenever it is brought to the client house it starts to freeze and behave like crazy. No BSOD just plain freezing. He told me that the last time it beeped.
I already brought it back and forth three times and it's always the same thing. I am pretty sure that there is nothing wrong with the computer or with the software installed and now I am trying to figure out what is going on. So what is the different in my place (beside my charm)?
1) At the client house he uses a horrendous $15 cheapo voltage stabilizer while in my workbench I plug the computer directly to the AC outlet. I vote on it as the culprit.
2) The client connects the computer to the Internet through a blue LAN cable while in my bench I use a USB wifi adapter. Nonetheless we use the same Internet service (radio) because we are in the same neighborhood and there is only this service around. It's possible that the computer may freeze with his network but not with mine? Hmmm... never heard of it but...
Anyway, there is over 2 hours that I brought his computer back to my office (again!) and it's running seamless over my workbench since then...
Ideas?
EDIT: Actually I remembered about another thing that is different in both places: the monitor. I use a small 15" Dell screen in my workbench while the client uses a 22" wide one. I am not using the latest Dell drivers but the ones that comes with Windows and that installed automatically.
