I have a 6(ish) year old Toshiba Satellite Pro L300, original spec apart from several new HDDs, replacement RAM to bring it up to 2GiB rather than 1 and a broken motherboard connector which stops my DVD drive from working. It's running Linux Peppermint. About March this year it started taking 3 or 4 attempts to boot, getting slightly further on each restart (which the computer did itself, I didn't touch it). I replaced the HDD which had 300,000+ bad sectors, changed OS from Ubuntu to Peppermint and ran a MemTest which came back clear. I don't think it's the CMOS battery as someone suggested as the clock is always correct and if I unplug and plug back in within a few minutes it will usually start normally. Now it's taking upwards of half an hour to boot, restarting over and over again until it gets to the boot select screen and then will sometimes restart several times once it's fully booted and I've started using it. Anyone have any idea what's happening? It's getting pretty irritating now.
EDIT: It's also started freezing regularly and presenting me with screens like this;
