PC will not boot up.

I was using my PC the other day, and working on a couple of projects when suddenly it froze. I was completely frozen, so I held the power button in and booted down. When the computer booted back up, it hung up on the boot for a very longtime, not showing anything until I saw the windows is opening logo. So I think all is well, then I use my PC for around 15 more minutes, then bam, computer freezes again, at this point I know something is fishy. I boot back down by holding the power button in again. The computer starts up again (fans and leds come on) and nothing ever happens. Any ideas what the issue could be? Power supply perhaps? Thanks.

To me, it sounds like your power supply might be on its last thread. It could also be your computer overheating perhaps... it's a desktop, right?

I get no picture whatsoever. The computer turns on, and no post. The odd thing is, nearly the exact same thing has happened to two of my PCs within one week of each other. They are both desktops, and they have very similar builds. They have both worked fine, one for about one year, the other for two years. I do not think it's an overheating issue, as they read fine as far as temps on speedfan.

I'll try swapping out the power supplies and see what happens. I can only hope this will fix it!

I had a ram problem that sometimes stopped the computer booting. You might want to check ram too.

Im guna say its a heating issue. Download Hwmonitor and report back with the temps listed under your cpu.

The thing about a random hang-up like this is it could literally be any piece of hardware inside your computer, a Windows software issue or perhaps a virus. Since hardware is usually suspect, test that and get it out of the way first. Typically what I've seen from a PSU issue is computers that will run along fine and thensuddenly reboot themselves. The cycle happens faster and faster untilyou're constantly rebooting. That being saidI don't think I've ever seen a power supply issue that cause Windows to lock-up. Are you comfy opening up your case and do you know your way around inside? If you do, look on the mainboard's capacitors and see if any of them are bulging or leaking. Also, check to make sure the CPU fan is spinning and listen to the hard disk for any clicking noises. If all of that checks out take out the RAM sticks one at a time and see if one of those is faulty. Let me know how all of that goes.

Maybe its the Ram or the PSU. Clean your Ram well and insert it back to see if it works. Or if you have two Rams, try unplugging one and then boot your PC. If this works, then the the unplugged Ram is causing the problem. So, get one Ram from the store if this is the problem. I too had problems like this before and when I cleaned my rams and inserted it back, it started again.

But virus doesn't interfere with the booting. If the system is corrupt, then it'll surely show the Boot screen and then the HDD error appears. It must be the problam with the Ram or the PSU.

It would take more than one bad capacitor to bork up a system wouldn't it?

I thought the others pick up the slack but have a shorter life because of the extra load.

Might be your cooling, maybe the heatsink has come loose and even though you hear it working it isn't getting good enough contact to cool? I don't think it's the PSU it shouldn't cause freezing it would just drop all power without warning if it was PSU. Since it is no longer getting past the POST i recon your CPU may be fried or motherboard due to overheating, if this is the case the only thing you can do is replace them or swap them out and try again if you have the available parts on another machine you can borrow.
