I received a called from this number and a heavily accented foreign male said he was calling about my computer problem.  I asked several times who he was with and why he was calling.  He continued to respond he as calling about my computer problem and kept asking questions.  I eventually told him I had no computer problems and hung up.  After shutting down my system I now find that it will not reboot.  Bit of a stange co-incidence.  When I received the call I had experienced not problems, had not reported any problems but now my system will not boot.
