Yes it sounds like a hardware problem, if not then it could be some sort of virus or bug.  I would do a virus check and a hardware check.  Like run a diagnostic test on your computer to make sure all the hardware is running properly.

Have you tried disabling your screen saver?\n\nDo a scan and repair on your hard drives.\n\nWhen the Internet locks up do CTRL ALT DEL and see if there is anything not responding.\n\nShut down all unnecessary programs & see if it happens. If not reactivate your programs until you find the culprit.\n\nIf you have your hard drive power down after a period of activity disable the power down.\n\nI will assume you have done virus & spyware scans.

im not sure..\nbut it's happened to me before.\nthe freezing of the mouse may be due to adware/spyware so you might want to scan your system to rid of them.\nor.\nthe motherboard could be old/ and may be on its way to ruin.

Uo oh...Sounds like a virus to me. If you don't have anti-virus, get it. Two good freeware programs are Avast & AVG. Your anti-virus must be up to date too, new viruses as created every day, your software has to know how to recognize these viruses. I agree with the last fellow too, it could be an overheat issue, but I've never seen a PC recover from an overheat lock-up.

have u run an antispyware and an antivirus program by any chance? might be malware/virus, etc...\n\nif not that, then could it be perhaps the way u r connecting to the internet...depends on if u have dialup,broadband,cable,T1,etc...???  \n\nr u having a conflict in some of the programs downloaded on your pc???  \n\nalso, do u notice if ur pc freezes up on certain sites or is it just random... how often does it freeze up? how long are u on the web b4 it freezes up? do u remember what exactly u were doing at the point of it freezing up? is there a pattern to it?  \n\ncould be lots of reasons...  start with some of the above, brainstorm, ...\n\nsome good sites i use are:\n\nbleepingcomputer.com\ncomputerhaven.com\nvideoprofessor.com...\n\ngood luck.let us know how things work out 4 u...

A) run defrag  (if you cant find it search your computer for it through start -> search\nB) Try deleting stuff that you don't use.\nC) Buy more RAM\nD) Buy a better graphics card (it has its own memory s well)

Check all cable connections, mouse, monitor, AC power cord etc. sometimes they work loose. If everything appears OK, you may need to reload windows. Some viruses will do this by corrupting your program files. You can try a emergency disk, restart in SAFE mode, or just format the drive and reload Windows and all the drivers. I do this about every 3 months to clean out junk and corrupt files. You will find your PC runs much faster.

I have a Dell computer, about 8 months old,512 RAM-100gigs hard drive, and it has been doing stuff like that from day one. Just spent $200 on a new hard drive, and it helped a lot, but it still does it {freezes up} from time to time. Guess Dell computers are just cheap pieces of sh*t. Hope yours isn't a Dell. \nDe-fragmenting and disc cleaning helps, but isn't always the answer to the problem. Be sure to check for spyware. Spybot is a good spyware remover.

This could be a cooling issue, check your fans and dust out your system. I saw one system the other day that did this because of the massive amount of dust, even though the fans were still turning. \nAlso try starting the computer in safe mode and see if it works then or locks up without restarting. A bad XP install will cause this sort of action. Sometimes there is a bios option that tells the system to restart on error, you can turn this off to help diagnose the problem.

Try hitting Ctrl+Alt Del and checking your system resources. Select tasklist and look at your Processes Tab then look at what is using the most CPU. If you can see something rising to the top ie.90+% then that could be the cause. \nAnother reason could be that something is overheating and could be taking 20minutes to reach lockup.\nAlso try switching off yer firewall temporarily. Software such as Norton can be quite sore on your pc. I had this happen on a laptop recently and switched to mcAfee and problem resolved. Lockups however in this instance where for 3-4 sec then ok for 10 or so then lock up again.

Check your hardware in device manager and see if there are any conflicts,(yellow ? marks), beside your display adapter, your monitor, and your sound drivers), sometimes a driver can come corrupt and you may need to update it. also? The defrag could have defraged a file in your registry that is no longer used, I recommend buying Registry Mechanic, this will fix any errors in your registry that can also cause freezing. One last thing? Go into safe mode, and do I scan on your hard drive for errors, make sure before you do the scan? That the box is checked for,"automaticaly fix errors". Then when thats all done? Do a defrag in safe mode. There are other causes for computers to freeze, but lets see if these few tricks will do the trick first.

Could be the cooling fan or the hard drive. Check both.
