Hey guys, I recently bought a 44 inch plasma screen TV so i can get a much better gameplay on World of Warcraft, and oh boy the plasma screen is amazing. Its been working great and amazingly for 2 days. Now im having a serious problem. Whenever i log onto World of Warcraft about 10 mins into gameplay my screen says "No Signal" but my computer lights,keyboard,mouse are still on, i can tell by the laser light on the mouse and the num lock on the keyboard. The game in WoW stops and i cant do anything. I have to shut down computer and restart it back up and its been about 20 trys and still the same problem ive been getting. I think its my GPU. I took my case off to see if i noticed a differnce, i notice a HUGE differnce on how hot my GPU is after ive gotten into WoW. it goes from 55c idle to 60-75c while playing the game. I have a GTX 260, amd 6000 3.1 ghz, 2 gigs ram and an asus mother board. Thanks in advance.

Justin Boult-Monitor says No Signal (1-12- 2010)

Justin – Welcome to Geeks to Go –

Looks as if you are experiencing – an Overheating Problem -

I have a few questions – in order to determine a starting point – and possible cause / combination of actions -

• How old is your PC?
• Purchased –[Already Built] Or did you [Install Components]?
• Is Video Card – Recent Update or Original Equipment?
• Did you have GPU Overheating with old monitor?
• How long have you had New Monitor before Heating Problem occurred?
• Are you Over-clocking GPU an/ or CPU?
• How long have you had - World of Warcraft -

Is the fan on your video card rotating?

The GPU physically takes up 2 Card Slots –
Is there a PC Card in the next available Slot? The GPU Fan needs space to – Breathe
In fresh air –
Is there card or cable or other obstructions to the Air flow of the GPU Fan?

Does the overheating occur only with this particular Game – or does it occur with other applications or games?

The GPU requires a 500W PCI Express-compliant system power supply with a combined 12V current rating of 36A or more – Plus - Two 6-pin PCI Express supplementary power connectors

Can you monitor your 12V Power & GPU Temp - & see when – [No Monitor Signal] occurs?

Also examine the Power Supply connection to your - 44 inch plasma screen TV – It may not be properly & fully plugged in completely / properly – both – Power Outlet & Plasma Screen – connections –

Also try reseating your GPU Card – (WITH PC SHUT DOWN & POWER DISCONNECTED -
