I have a brand new PC (2 months old) and I had to send it back to the shop last week because, randomly, the whole thing would lag and when I say lag the mouse jumps, media plays for a second, stops, plays a second, stops, and anything the computer does it, does it like that. The guys at the computer shop say they ran CPU intensive programs on it and it was completely fine for the whole week and the weekend but as soon as I went on it for a few hours it came back. WTF? It has:
Intel Core i3
2TB HDD
HD Radeon 7750 1GB
8GB RAM
I have found that if I leave it it will go back to normal for a few minutes but will then go right back to being laggy. It wont go back to normal until I restart the machine. I said bbefore that it's random and it's so random that it can happen as soon as the desktop shows up or not for a full day. I am offering a reward of $100,000,000 to the first person who can fix this problem for me

Sounds like either a RAM problem or a hard drive problem. Do you know the specs of your hard drive? I know 5400 rpm drives occasionally act up.
As for the RAM, have a look at RAM usage in task manager. Let me know what it says.

It's not the RAM, don't know about the HDD though but it's a 7,200RPM

It was a long shot with the HDD anyway, if it's a recent 7200 rpm drive, it's not likely to be that.
The only other thing I can think of, like I say, is the RAM. What makes you say that it isn't?
I suppose it could be the operating system, but they'd probably have spotted that when they stressed the CPU.

I ran a scan of the RAM and it came up clean

How confident are you going inside the case to fiddle with things?
There may be a problem with the RAM that the scanner missed. The way to check it is to remove all the RAM except one stick. If it still lags, try it with another stick instead. If that fixes your problem, you know the first stick was the issue.

i'd start by ruling out software issues ... i.e. backup all your stuff and reinstall OS

@SilentRage I would have built the computer myself if my parents hadn't been so paranoid about me f**king it up so going inside is no problem
@JSnows Tried that a number of times

Like has already been mentioned several times in the thread, it most definitely sounds like some kind of RAM issue, and using the hard drive for swap files.
The telltale signs which you speak of, include-
lag affecting everything, such as mouse movement, media playback, programs hanging
intermittent periods of excessive lag
that same lag returning periodically until the next restart
restarting your computer resolves the problem longer than the time between lag spikes
If you can leave the Task Manager running in the background while you do your usual things (assuming you're on a Windows PC), and when the lag seems to be kicking in take a look at the Physical Memory Free, watch that, and see if it then increases dramatically shortly after the lag has stopped.
If it does, then take a look at the processes tab of the Task Manager, and order them by Memory (descending). You may find that there is something running in the background causing the lag.
At the very least, doing this, at least you can rule out obvious software being at fault.
(I'd take a look at doing this, because one of my old laptops used to run software called Live Update from time to time, it wasn't in my startup software, and when it ran it tried to use more memory than I had available, by a long shot, and everything would freeze or jitter over a period of about 5min before the stupid software would finally crash, and free up the memory again. Turned out that it was a scheduled task, running on various triggers, which was already there when I bought the laptop brand new)

If it's not RAM or a software issue than you might have yourself a virus/trojan.
I suspect the guys at the PC shop didn't have it hooked up to the internet when they tested it. If it's a trojan than that means someone is controlling your computer through the internet. It would explain your computer's symptoms. Try having it unplugged from the internet (unplug the ethernet cord, AND made sure your wifi is turned off if you have it), turning it on, and using it to see if that solves the problem. If so than this theory will be true and you'll need to do a complete reload of your hard drive (from scratch since any backups you may have may contain the trojan/virus) since any data on it would be at risk of having the trojan. The other option would be to give it to a pro who specializes in cleaning up viruses/trojans.

You need to run ram tester for more than 8 hours to see if it's a ram problem. Ram problems would normally freeze/bsod your comp. Running a ram tester would require you to restart your computer and boot up from an external drive tho. A good tester can't be running alongside with windows.
Anyways, I don't think it's a ram problem. I think it's just a bad hard drive problem. You might have just gotten a lemon. Those things happen. Any noise coming from it btw? What you can do to try to alleviate the problem is turn off pagefiles to your hard drive (you have 8gigs of ram, you shouldn't run into problems unless you plan on opening a lot of things at once if you disable it), and mess with some settings to always keep your hard drive on. Check the power settings and change it so it never turns your hard drive off.

Reinstall Windows.
Choose the save documents option.
If problem still persists, then hardware problem.
Start narrowing it down.
Start taking out RAM chips. Take one out, test PC, if lag still persists. Take next RAM out etc, continue until you find the culprit RAM stick.
HD issues harder to deal with. Boot up on a live CD OS, preferably Linux, download some drive scanner that checks for bad sectors on HD, if found, well I'm afraid you can't do anything, apart from buying a new HD.
There you have it 3 most likely options:
Software, RAM, HD.
