This is very likely a hardware related issue. Please supply the specs of the computer in your next post, a make and model will help with diagnosis and testing procedures.

 

Here are some things to try: reseat your ram, (unplug the computer and remove all power including a battery if it has one). You can run memtest to test the ram, often a bad stick of ram will cause crashes and possibly artifacts memetest can be downloaded here: http://www.memtest.org/#downiso

 

They have either disc bootables or a new flash bootable version. Backup the data on the flash drive if you decide to use it, it will require a format. Boot to memtest and let it run for 3 passes at minimum, if you have any red lines (errors) report all of the information in that line in your next post. Also please let me know what size stick of ram is in each slot if there is an error, I may be able to tell you exactly which stick may be the cause.

 

This also may be the video chipset starting to fail. I would recommend dusting out the computer while you have it open for reseating ram. If this is a desktop also check for bulging or blown capacitors on the video card and motherboard examples: https://www.google.com/search?q=blown+or+bulging+capacitors&biw=1272&bih=766&source=lnms&tbm=isch&sa=X&ei=gCZaVLyfEISjyASAxoH4Aw&ved=0CAYQ_AUoAQ#tbm=isch&q=blown+bulging+capacitors

I would still recommend running memtest just to be sure... Often times a failing video card will cause this exact situation as well. Safe mode may work due to the generic vga driver windows is using. Normal mode will use a full featured amd driver and that may be causing the crash due to failing hardware. You could try a bootable version of linux, something like mint and see if you have any crashes or kernel panics there. You can get linux mint here: http://www.linuxmint.com/download.php

 

Video cards (computers in general) need to be dusted out frequently or they tend to overheat, overheating even one time can cause permanent damage. I recommend dusting out computers at least 2 times a year if not more if you live in a dusty environment as I do, I have a wood burner, live on a gravel road, and have a dog. Heat sinks get plugged with dust and then they no longer cool effectively.

One more thing: sometimes a failing power supply will cause similar symptoms. If you have a spare psu or video card (same wattage draw video card) to test with, you could quickly rule either out.

Glad to hear you have it working.

 

Keep in mind it is still possible it is power related if you didn't try a different psu as well, it is unlikely with your current result. The 4870 will use quite a bit more power than the r260x under full load. Since you had problems even with the card at idle/boot, it seems most likely it is just the card.

 

If you experience any similar crashes with the new video card, I would suggest replacing the PSU next.

 

Happy computing.

I do the same about every 2-3 months. 7 years out of a card, that is a good run.
