Apc ups comes with inbuilt surge protection, there is no need of installing or using third party surge protector specially with some low amp rating for pc, which usually ask 13-15amp or even high amp. Surge protectors from belkin ment for electronic goods like lcd tv, DVD players, ect not for heavy hardwares with higher power requirements. I use belkin surge protector for tv, set top box and xbox, but not with pc. You should reinstall apc utility software immediately and see what kind of problem ups is reporting, for example: if ups is overloading than its actual capacity or giving battery problem ect.
