HP Pavilion DV7-6186eg stuck on windows starting screen

[lorcav123]

I need help with HP Pavilion DV7-6186eg.

It always stucks in boot on Windows 7 starting screen.

There were some problems in past with HDD, some bad sectors but I repaired that. Since that HDD passes all test.

I discovered that every time I install GPU drivers it stuck in Win7 starting screen. After I removed driver from safe mode it boots normally. Laptop has Intel GPU + Ati 6770M. I tryed disabling one of gpu in safe mode (maybe some gpu is faulty, device manger -> disable) but that didn`t help. It enters windows wit low resolution, in device manager it tells me for enabled GPU that there is a problem. I use drivers from HP web. Tried form AMD page, didn`t help.

MemTest 14 hours - OK
HD tune error scan, HD sentinel, Crystal disk info, WD data life guard, Seatools long generic test - All OK
Test form HP in BIOS - OK

I don`t know what to do anymore. I found out that there is many cases like this in HP forum, seems to me it is some driver problem, that GPU is ok. Advice?

I tried running Linux on USB (burn on stick with Rufus - Linux Mint, Ubuntu, Artixbang) so that I can eliminate that HDD is not a problem. It enters Linux and then freezes, resolution is higher that on windows so I think that when it activate GPU it simply freezes. With this I think that GPU is broken. What do you think?
