It sounds like it can no longer make use of higher GPU clocks anymore due to hardware fault, most likely the GPU would need to be replaced.
I would try it on a friends machine to make sure though first before spending any money on a replacement or contacting the manufacturer (if it is still under warranty)
no it is not under warranty sadly.
I have seen couple of poople openning thread with black screen issue having same card with me. Also there was a topic i mentioned earlier there are tons of people having same issue mostly having 270 or 370 series which as far as i know upgraded versions/replacement of 7850.
Do we absolutely sure mine and these people cards got bricked?
ps: I want to try very old drivers from CCC series but could not find them, could you provide me some link to them?
Hello again, i edited vbios, lowered clock speeds as much as it goes and re-flash back. But issue remains same, card working without amd-driver installed but not with driver.
I'm with the exatly same problem here. I'm tried almost everything you did. I blocked Windows Update on my firewall to avoid a crash update but I did not find the older driver version I was using.
My laptop intel i5 not switchable + amd radeon hd 7650m 2GB GPU i update Crimson then issue
started black screen on windows logon. then i clean the hard-disk ,installed new OS windows 8,8.1,10
when i try install any official stock catalyst or crimson ,DDU,amdcleaneruntlity,registry cleaner.
while installing display driver issue with black screen crash and some time mouse is showing flickering .....
i try many driver version not able install stuck or freezing..after only way hard shutdown
then i try uninstall amd display driver on safe mode then it able to login normal with Basic display adapter.
now unable to install any amd display driver for GPU it useless...
i have no found any solution in forums .
finally i find the fix for my laptop Amd HD 7650M 2GB + i5 intel
a.black screen issue when logon and b.installation black screen issue
1st try with hdmi / vga connected second monitor then try to install or try to turn on laptop still issue persists
it a hardware failure gpu dead.try below step it worked for me.
1. need "air heat gun" and "heat thermal paste".
2. disassemble laptop fully.
3.remove heat sink with fan from motherboard clean the fan dust if you have and now able to find chip process and AMD Gpu in laptop.
4.read the chip which one is GPU and take "air heat gun" blow up-to 5 to 10 min then wait to cool 30 min don't touch chip.
5.put the thermal paste on both intel proccess + amd gpu chip place the heat sink carefully.and assemble your laptop
6. turn on install any catalyst driver .i have install 15.11 catalyst (don't install crimson driver it burn your GPU)
it working fine for me...
this very risk i have sony laptop the company is closed . i have no choice to service. i done by myself.
it help someone keep try any dead gpu and black screen issue
so it is basically "baking" method. Anyway, we have dedicated post ongoing. There are couple of more people solved via baking but it wont last long. It is not preferable method either.
yes i actually tried baking (samething but using owen itself) and yes it worked for two weeks . It is not the real solution though and working time depends on how lucky you are. Normally professional people can repair soldering way better but unfortunately it is very hard work and hard work costs. Most of the time much more than working second hand of exact same unit.
