Hey Guys I need your help,

For about 6 months now my Windows 8 computer has been rebooting in any internet browser I use and the itunes store, but not while I play games or use any other programs. I'm desperate and I've tried so much to get it working, heres the list

-I've tried switching to other browsers
-plugging up directly to the router
-refreshing and reseting my computer (this works but only for a week)
-reseating the RAM
-disabling automatic crash restart in the internet setting

I really need help, does anyone know what could be causing this issue?
(Also if this is any help, I have Hughsnet (sadly) and every time this reboot happens it disconnects the ethernet cable or WI-FI connector, depending on which I'm useing)

THANKS! :]

You should include complete hardware specs for your PC.

The most common cause for random reboots without warning is a bad power supply.

Sorry here's my specs
-Gigabyte GA-78LMT-USB3 motherboard
-WD 500GB Hardrive
-ATX 400w Power supply
-1x4GB ADATA DDR3 RAM
-AMD Quad core processer (not sure what model)
-Radeon HD 7770 Video Card

Also I'm not having random reboots, it only does that when in internet browser or iTunes store.

There are hundreds of low-quality ~400W power supplies out there, you need to provide a brand and model number.

You could install HardwareMonitor, SpeedFan or other similar system monitoring tool to see what the CPU's temperature is just in case but my strongest suspicion is still the PSU - if you do not know what brand it is, I'm guessing it is just whatever the shop you got your PC from whacked in there and those are rarely any good.

I bought the computer from iBuypower so I'm not sure what brand PSU it is, I just wrote down what was on the side. Like I said though, I don't think its the power supply because I can play games like Skyrim and Dishonored for hours straight, but when I try to browse the internet it reboots ten minutes in.

And that can be caused by power supply issues too.

While most power supply problems tend to crop up when under load by stressing under-rated output caps, less obvious issues like feedback loop stability can crop up under low load. Your PSU might have trouble dealing with bursty loads like loading webpages where the CPU goes to full load for a few micro/milli-seconds when it receives a packet and processes it, wakes up the GPU to update the display, then goes back to sleep until the next packet, wake-up, sleep, wake-up, etc. Get the right pattern of power peaks and valleys, the feedback loop starts to oscillate, voltage or current protections trip and the computer reboots or powers down.

Sorry, kinda a newb and real ticked off about my PC, thanks for the response. BTW how would I test power supply issues, any programs or something I could use?

PSU issues can be notoriously difficult to identify.

If you have a multimeter, you can try measuring voltage rails by back-probing the ATX connector while the computer is on and see if all the rails are within 5% but that will not help you if your real issue is transient response - how quickly, cleanly and accurately the power supply responds to load changes. The only way to measure that is with an oscilloscope.

Your next best test is swapping out your PSU for a known-good one and see if your computer still has the same issues.

How hard is it to swap out the PSU? I mean could a newb do it, or should I take it to a repair shop?
And thanks for the help so far, really appreciate it.

If you know how to use a screwdriver, the most "difficult" step might be keeping track of where each cable needs to go and not get them mixed up.

The connectors will only fit one way unless you mess up the key alignment.

In terms of overall difficulty, I would call it trivial - just a little harder than adding an add-in-card in an expansion slot. Of course, there are situations where the case and motherboard layouts may add unexpected complications.

Open your case, take a look at how wiring goes all over the place and if you feel confident that you should be able to pull them out and plug them back in without stepping too far out of your comfort zone, you should be good to go. While you are in there, write down the actual brand and model of your current PSU.

For your replacement PSU, try to aim for something in tier-1/2a/2b or worst case tier-3 on this list:

Thanks for the help, I think I got all the info I need, going to start shopping around for a better PSU and some guides to put it in. Hopefully it should fix the problems I'm having.

InvalidError you're the MAN ;-)
