My Acer Aspire AX1301desk top makes a vibrating/grinding noise when starting up, which lasts for a couple of minutes, then gradually reduces.
I thinks it's perhaps the HD.
Can anyone advise me hwat I can do?
If it's a fan, you can clean it with a compressed air/solvent and place a drop of 3 in one oil on the center bearing. If it's a hardrive problem, you may want to get a new one and clone your old one before it fails completely. I use an ssd now, but if you can't afford one, check prices for regular 2.5 inch notebook drives. Prices are high right now.
