Hi all. Have tricky one which my guess is Bios corrupt or PS caps ect on MB? or hardware failure out of bios?
Splash screen comes up everytime and PS brick i use is ok as i use on other laptops sharing same big barrel plug.
F9, i changed boot order to boot from usb and i put a Win 10 stick in with empty good HD installed and it loads the little blue logo and round dots turning install. 10-30 secs later screen freezes and HD activity stops dead and then eventually computer shuts off completely dead, no lights. I also used a win 7 install stick and same. I have also had it kick back to bios screen? and even a BSOD with code for hardware failure? so diff outcomes but always no go for install. Major hardware failure Cpu? GPU" bios chip?
Bios is latest 2018 and i have played around in bios with default settings just in case it was all jumbled . Legacy is on and UEFI off, tried turning that on but all weird , so went back to legacy.
Also i ticked a box for Bios upgrade and it said it would upgrade from usb stick next restart but that didnt work either. i have never seen the upgrade screen ever- cant flash bios in case bad?
Am i losing power on the board and its locking up? or is bios chip bad ? or something else? pulled board all looks normal and sockets/connectors all there and turns on every time , just cant install windows or get much past bios. Do my own electrical repair so can swap out parts if needed and start testing inrush/ caps/secondary bucks ect from PS socket forwards although not expert on laptps.
I also used the diagnostics menu and tried all diff tests but after a few mins of testing it also killed the laptop dead too?? earlier it got through the easy ones like memory. i swapped the mem with same from other good computer so cant be them.
Thanks for any assistance
