The "minimum" specs for Win 7 are:
1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
16 GB available hard disk space (32-bit) or 20 GB (64-bit)

If by "less than a gig" you meant hard disk space then it probably ran out of room.

EDIT: In fact you did well to manage to even install Win 7.

Always pop back and let us know the outcome - thanks

Can you boot to the OS at all?

If you can, does it have any error logs pertaining to the shutdown?

What OS is this?

Does the computer POST?

Have you tried booting from a linux live CD?

Why were you re-installing it? Maybe the problem you were trying to fix was actually a hardware fault and it has reared its ugly head again.

Ok Derek thanks mate that all makes sense I do apologise it has about 75 gig hdd but only 512 mb ram sorry its been a long day, lol, even thow there's not enough ram would that cause it to shut down after a few seconds tomorrow I'm going to take off the side panel and check for dust it hasn't been used before today for about 3 yrs, so ill keep you informed I should have some spare ram knocking about, but I do appreciate your help on this matter, 😊

Ok, I understand the HD size typo.

As regards RAM bear in mind the MS minimum specs are highly optimistic. Computers which just meet those minimums "crawl". They might run Windows but put any programs in and they are hopeless.

If you can't get your hands on a bit more RAM (2G if possible) then maybe Linux would be a better choice. Old RAM is usually very expensive to buy.

Good to hear.

"regarding ram is it a case of if it fits in the slot it will work"
No, not necessarily. Best place to get an idea is to go here and run their scanner

OK. If you want to look at temperatures try this freebie:
http://www.cpuid.com/softwares/hwmo...
(if your motherboard has temperature sensors)

Another one that can cause this is oxide on RAM edge connectors so it might be worth cleaning their edge connectors with a soft pencil eraser then popping the stick(s) in and out a few times to get any oxide off the sockets.

Events might tell you something but concentrate only on anything that shows at the time of the restarts, because chasing "all" events is probably not worth the effort.

Good luck

Right thanks mate ill do that, I think if symptoms persist ill try again wit another old pc I have it runs fine and has 2gig of ram but the HDD is very small so if I take out the HDD from the faulty pc and put it into the other that's running fine mabe I can make one half decent pc out of the two, now I'm starting to ask myself why I didn't do this to start with, could it be that simple? Anyway Derek will keep you posted thankyou for your help, the reason I'm doing all this is to give my niece her 1st pc it only has to handle fb and youtube so thought id give it a try before paying silly money 💵 for a 2nd hand one, thanks again mate, you rock! 😊
