Be sure to tell more. It could be simple heat issues that cleaning could help to other known things like the HP DV6000/9000 laptops to a gamer PC that needs work.
I have a 32-bit Vista OS and since yesterday I havent been able to start it in the normal mode as it freezes minutes after startup and I have to force shutdown.
I have uninstalled a lot of programs which I downloaded in the last few days, ran memory diagnostic, tried to find a restore point, ran malwarebytes scan but unable to fix it. I did a clean start, with all non MS programs disabled but that didnt help. Is OS reinstall the only solution?
