Hi, first post to this forum. Hope someone can help.
Bought a new desktop running Win 7 64bit in September and at same time changed ISP to cable for fibreoptic. At first download was 60+mbps . Checked a few times using speedtest.net and always the same, so stopped checking in early November. In December bought a Radeon graphics card and in January realised that internet was now really slow. Numerous checks on Speedtest gave between 1 and 3 mbps. Tried disabling various things at startup but no change. Finally, two weeks ago took out the graphics card and went back to the Intel on board graphics.
Instant success. 60+ again. Then realised that among the startup processes I had disabled was networking so Home Group was not available. Went back to "normal" boot and immediately Home Group started working but speed went back to 1 to 3 mbps.
So, started in Safe Mode and back up to 60+!
Question is, was it just the graphics card and associated software or some other process? If anyone can give me some guidance I will be most grateful.
Incidentally, it is not an ISP problem as my Linux laptop has been giving 60+ mbps the whole time.
Have run CCleaner and Malwarebytes to no avail.
Thanks in advance for any advice.
