[Resolved]Slow down in games/Full screen video

[Link]

ATI 5770

One game i have actually looked at - MW2

Yesterday Maxed out - 100+ FPS
Today Lowest settings - 30+FPS

Same problem with TF2

Video play back, not HD average quality AVI, 25fps at start, full screen 10-15

Only problem i have had is my Master boot drive playing up, managed to sort it out with a chkdsk, and currenty de-fragging and Virus scan.

Halp? :<

Re-installed drivers, older drivers and reset clocks to default.

Check your GPU/CPU/RAM temperatures.

Something sucking up CPU?

One time VLC decided to not just quit like normal, but silently crash while having its window disappear. I unknowingly had a vlc.exe sucking up 100% of one core until I noticed like 2 days later.

What does catalyst say for the GPU utilization? when it happens?

It's fine windowed?

I managed to fix it, down to a faulty SATA cable on my boot drive, and re-seating my card.

Just spent 2 days trying to fix that hard drive, and it was a SATA cable :I
