My Laptop freezes a few minutes after start-up

Hi,

so here's the full story. A few months ago my Laptop went freezing from times to times, for a few minutes and then un-freeze, to freeze again a few minutes later. So wondering what to do, I formatted my laptop to solve that problem. Sadly it didn't worked.

Having work to do i was forced to run my PC on Safe Mode for a couple of month. After a while I decided to go ''legit', again and I realized that my PC froze a few minutes after start-up but after a couple of hours, it would run smoothly for days. So the past few months my PC was running smoothly,... until recently, but now, it's worst than ever.

It freezes a few minutes after start-up... and even if I keep it on for days, I still can't do a thing, it un-freeze for like 2 seconds sometimes, then just to freeze again. It's driving me crazy. I'm planning to buy a new PC but I'm stuck with this one for a little while now, might as well try to do something with it. I don't think this is a problem of program or anything like this since even after I formatted it, I still had the same problem. Is my laptop just dead? (I'm on safe-mode right now).

So here's my specs-

Toshiba Laptop
Processor: AMD Athlon 64 x2 Dual Core TK-57 1.90ghz
Ram: 3 Gb
System : Windows 7 home premium 32 bit

Any advice would be greatly appreciated, thanks!
