Sorry about the title I wasn't sure how to put it.
My newly built computer seems to have an issue with either the graphics card or the monitor or both and i am not sure which. The three problems I have are the windows aero animations have gone into slow motion as if the GPU can't handle them (it is the same for games) Also the monitor sometimes randomly goes blank while I am using the computer (most often when something graphically intense comes on screen) When I say 'go blank' I mean the desktop dissapears off the monitor but the monitors back-light is still on, I think is the computer crashing but can't tell because the monitor isn't showing anything. Finally the colors sometimes bleed in certain areas. Here is a demonstration of the bleeding. http://i41.tinypic.com/jkc183.png
What confuses me is that my monitor has different issues when plugged into my mums mac but still doesn't work properly. Also my mums monitor works fine in her mac but I still have all the same problems above when it is plugged into my pc.
Here is my PC spec:
Intel Core i5 2500 @ 3.30GHz
ATI Radeon HD 6870
MSI Motherboard H61
8GB RAM (all being detected correctly)
Corsair CX500 PSU
Seagate Barracuda 1TB
LiteOn IHAS124 24x
Here are the drivers I have:
My monitor (Novatech 24" Widescreen LCD Monitor Full HD) - I can't find any drivers
Mums monitor (Dell SE198WFP) - Driver version 126.96.36.199
ATI Radeon HD 6870 - Driver version 11.12
Thanks in advance
