Also, having to first do VPN is not an option because the computers from which I need to access mine would require me to setup said VPN connection (not always possible due to lack of admin priviledges). If I tunel that through my VPN server, which I have, also, the speed drops considerably. When in need, I neet it to be fast: I sometimes use for example CAD/CAM software through RDP. I do that because I need it: for work and hobby related reasons I require to access my computer through RDP frequently. It is behind a router that only forwards RDP to my computer. Hi, Just to clear up a few things: My PC is NOT connected "directly" to the internet. Can I change the port number to something exotic? If so, how? -> Just found this: Regards, Vitor The thing is: how do you guys get into your computers remotely over the internet? I use that A LOT. The debate is not how secure my password is - apparently it is good enough to not have been hacked. So: there are ASSHOLES trying to do brute force attacks on all IP's that offer RDP and this causes the screen to flicker/flash due to the way Microsoft implemented the login routine. So I went to my router settings and disabled the RDP forwarding to my computer. Every 1-5 seconds the monitors would flash briefly (black). Can it? Could this be someone trying to RDP to my computer and doing a brute force password attack? Disabled the network and guess what: the flashing was gone! 11) Activated network and flashing was back. Looked it up and got some hints it might have to do with RDP? WHAT? That cannot be. There was a strange entry (cnvwmi service_control_sessionchange). 10) Had finally a good idea: looked at the Event Log of Windows. Must be a software issue? 9) Spent ages killing processes and stopping services. Strange: apparently the problem was fixed here. So I did a reboot into Safe Mode with Network. 8 ) Considered reinstalling the whole Windows HDD, but was not into that. 7) Put back PC in its place under the table, connected all cables, while wife was complaining about the noise. Rearraged the cards so that the GPU would have better airflow. 6) Thought it might be due to hot weather and PC getting too hot. STRANGE!!! At this point I thought that the GTX660 was broken. 5) Replaced the graphics card with a Nvidia Quadro. Plugged it into a totally different monitor with a different cable. 4) Unplugged the PC (a lot of work, as it crammed with cards and has a ton of cables attached - under the table). 2) Turned on each monitor, then using only one monitor a tine. My PC has 3 monitors attached (via HDMI, DVI and VGA), using a Asus GeForce GTX660 graphics card). It got worse with time and tonight I decided to tackle the problem. It is as if the screen went black for a fraction of a second. It started some weeks (months) ago with my monitors to flash briefly occasionally. Hi, I am describing this, just in case someone is suffering from the same.
