PC at very high CPU usage levels (80-100%) When only running Firefox+msn+Steam

[ashxu]

My specs are:
1gb of ram
2.13ghz Single core
128mb ATI MOBILITY RADEON X600
70gb HDD, 10gb free
It's a laptop

Ok, my highest memory users are Firefox, msn, steam and nod32, the rest are pretty low usage.
So i'm fucked, i can't do anything. The strange thing is, sometimes it's at 80-100% CPU usage, and sometimes it goes down to 10-50% for awhile. I'm thinking of defragmenting my HDD, but it'll take a shit long time (more then 24 hours i think, HDD is only 12% defragmented)

Any tips Facepunch can recommend?

Also reformatting is not an option, since i have nothing to back up my HDD on. I can't even run TF2 now :sigh:

I've been googling solutions, but it only comes up with stories of idiots that have shitloads of viruses on their pc.

Run virus scan with NOD32 and Spyboy S&D

[Daniellynet]

Remove: msn and nod32.

After that run a virus, malware scan.

Yeah i will. But i doubt it'll come up with anything.

nod32 IS my anti-virus

[ReznorT]

Try it without steam running at all

Yes, but with another one.

Try opera instead of firefox... it might work faster...

(If it doesn't, switch back!)

I don't understand the problem. All you've just said is how your CPU usage goes up to 80-100% while running three apps at the same time. Thats to be expected, with your specs.

If its speed thats the problem, try upgrading to 2 GB of RAM.

Probably a pentium 4. Thats your problem right there.

Don't say I'm wrong. Ive had the experience.
