Hi all. I've been having a lot of issues with my system lately, I'll try to make it as clear as possible.
Windows 7 64-bit
AMD Phenom II X4 945 Processor
AMD Radeon R7 200 Series
Cintiq 22HD (monitor)
Power supply is 750 Watt
Computer is about 5 years old
Current problem: Computer randomly freezes. I'm not clear if the computer is completely locking up, or if the video has stopped responding. It's happened while I'm checking email, watching Youtube, playing games, and sometimes happens as early as 10 minutes into the session. Sometimes the screen goes black, (it does that sort of fZzt thing at the bottom like when an old TV loses reception, but the monitor is still on and says nothing about losing signal) sometimes the picture freezes. An interesting note is that I have my headset plugged into the monitor via USB - sometimes the sound will go when the freezing happens, and other times the picture will freeze but the sound will continue.
I thought this might be an overheating issue, as the first 2 times it happened were on a pretty hot day, but I can't really see the computer overheating after just starting up and jumping on Chrome. I'll also add that the hardware sounds normal, it doesn't get loud or quieter or anything when the problem occurs.
Background: Everything was great until I got on a plane and the Airline tossed my luggage around, damaging the video card (Card #1 - Radeon HD 6870). Upon arriving, the screen wouldn't turn on, or it would turn on and there would be big green bars across it...it was unpredictable from boot to boot. So a friend gave me a low end card, 256MB (Card #2) to tide me over while I got a new one. On the second card I was getting a lot of blue screens and had to really watch what I was doing simultaneously. Finally I got my current card (Card #3 - Radeon R7 200 Series) and things got a little better, but there were still occasional BSOD. Following the advice of some gamers, I reverted to an older version of the video driver and it improved everything, until I started having this recent issue.
While trying to solve the BSODs, I covered a few things -
1) memory check and reseated memory
2) reinstalled video drivers about 4 times
3) watched video card temperatures
4) power supply?
