OK you could try disabling some unnecessary services OK first make a restore point just in case you disable some system ones accidentally then go into run and type services.msc and hit enter then go disable these services: Alerter, Clipbook, Computer Browser, Distributed Link Tracking Client, Indexing Service, IPSEC Services, Messenger, Netmeeting Remote Desktop Sharing, Portable Media Serial Number, Remote Desktop Help Session Manager, Remote Procedure Call Locator, Remote Registry, Secondary Logon, Routing & Remote Access, Server, SSDP Discovery Service, Telnet, TCP/IP NetBIOS Helper, Upload Manager, Universal Plug and Play Device Host, Windows Time, OK it looks like a lot but it helps
. hope it works mate and good luck
