Screen will suddenly be pixelated and only a manual restart will work (after cleaning).

ZackBack · Apr 30, 2015

I had a few issues with my computer, whether the pci-e slots wouldn't work or the graphics card will heat up to almost 100*c (210 Fahrenheit). So I decided to unscrew my graphics card, clean the dust out and put new "Thermal Paste" , I was very careful with not messing up anything.

I cleaned it, put it back and whenever I run something like a game or anything that will usually heat up the graphics card, the screen will get pixelated and only a manual restart will work. If I don't run anything the computer can stay awake for hours with no problems.

Specs:
GPU - AMD radeon hd 7900 series

Motherboard - MSI X79A-GD65 (8D)

RAM - 16gb

CPU - Intel Core i7-3930k @ 3.20GHz

That 100c is very bad for graphics cards, it most likely has been fried and thus is unstable. I think you may need a new card.

Another monitor cable,

Another monitor,

Another graphics card.

Robert Cook :

High temperature was normal for this GPU, 100 was rare but it happened. Usuauly it reached around 90c.
Could that be because I screwed something up when opening the graphics card? I doubt it but maybe?

i7Baby :

Ill try another cable, monitor..
How much will cost a graphics card with similar specs? or maybe better even.. but with reasonable price.

NOTE: When it gets pixelated, I can still hear sound for a few more seconds untill it completely stops.

Card cost depends on the exact card. Yours is '7900 series'. But nothing specific eg 7950, 7980, 7970.

A 7970 is now called a R9 280X eg http://www.newegg.com/Product/Product.aspx?Item=N82E16814202137&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=

i7Baby :

Looks like a nice GPU, can I get some more help/tips or whatever to try before I purchase anything?
yes, It only started to happen after I opened the GPU and cleaned it. Could it be related to the old Thermal Pads it has? since its the only thing I haven't switched? (NOTE: Thermal Pads not Thermal Paste)

Please help.

See if another graphics card works or if your graphics card works in another PC. Adding thermal pads wouldn't harm it if done properly.
