Infinite Loop Fix Looping Power Supply
Sep 9, 2002
The best solution to most issues with looping is POWER SUPPLY. Due to the huge amount of resources that video cards, sound cards, larger cpu's, they suck your power supply to the point that application cant perform. In turn it causes lockup, reboot and boot to desk top.A lot of resellers are only slapping in a 300watt power supply in newer systems. That doesn't work, you need at least a 400watt or greater. You need at least 450watt POWER SUPPLY. Take my word on it.This is the biggest issue i have studied on the net and in my lab for 1 1/2 years now. So many people have taken components back to the stores had them tested, to find out there is nothing wrong with them and go around shaking there heads in wonderment, without even considering power supply.

Computer is not is a very slight increase in memory voltage. i have tried basic standard voltage setting as well as slightly higher settings. A game, or anything using 3d or direct x causes the problem. at first i got a hang and total system freeze. had no error or bsod.specifically the game was FSX sp2. also occured with command and conquer red alert 3, and sins of a solar empire. additionaly 3dmark06 did the same thing. specifically the games or program would load fine but once it started the first screen or opening graphic it just freezes the entire system. i have to reboot via reset button. and windows load just fine. only 3d programs or games does this. no bsod until last night i finally got the nv4_disp infinite loop error.

Ok, I have solved "MY" nv4 loop error.It is not a software fix however. After I and most people have tried every fix out there, I decided to go to the root of the problem. The memory. I ran boot up with each DIMM alone. I use 3 1gb OCZ 6400's . 2 of these DIMM's ran any program that crashed before with no problem, only 1 did not. I ran the 2 DIMM's together and no more error. I have heard that there is an issue with the 680i motherboards giving incorrect voltage to memory or that it reads incorrect voltage . In either case on memory module is bad. While I consider this a final troubleshoot victory , it isnt cheap. But none the less im happy with the outcome.

I decided to do a fresh install of Windows XP Home. So, I put in the WinXP Install CD and set the BIOS to boot to CD. I deleted the partition (only one on my 60GB hard disk), created a new one, and formatted it NTFS - all by following directions in the Windows XP Setup program on the CD. Then I chose to setup WinXP on that formatted partition. The CD copies a bunch of files over, then tells me to remove disks and restart the computer. So, I do. I boots to the hard drive and gives me the "Windows XP Home Edition" screen with the moving green bar at the bottom while it's loading. Then it quickly goes to a rather blank screen that says "Setup is being restarted," strange moving lines cover the screen, and the computer restarts. It then does the same thing over, and over, and over again. I've tried repartitioning and restarting the setup process several times, trying every available option but after Windows Setup restarts the first time, it gets into that infinite loop of never proceeding to the next step of setup.

I changed the BOOT.INI section of msconfig to boot windows in Safemode. Upon getting in Safemode, the computer finally recognized USB devices and the CD drive again (wasn't doing so in normal mode). So, I insert a Windows XP disc, used the Advanced install mode (the one that overwrites the previous installation of Windows), and everything seemed to be going great.
However, the machine restarts and tells me this "Windows XP Setup cannot run under Safemode. Setup will restart now." and has an OK button. I click it, thinking it's going to boot into normal mode. Well, it doesn't. It boots up again, says the same thing.I click OK.Restart.Again.OK.On and on into infinity.

I was attempting to boot into safe mode through the BOOT.INI /SAFEBOOT function in MSCONFIG. After restarting to boot into safe mode, my computer would restart ten seconds into the login screen. This happens every single time and I cannot get back into Windows to uncheck the /SAFEBOOT box. The computer that I am typing on right now allows the user to choose the boot method before entering Windows. It has an old ASUS board and is running Windows XP Pro w/ SP2.
My primary computer (the one that is restarting) has an ASUS A8N-E and is running Windows XP Home w/ SP2, latest updates. Is there anything I can press (one of the F keys, perhaps?) that will prompt me to choose the booting method? Safe mode has restarted on me before, but not like this. I tried setting the motherboard to defualts in my BIOS, but that was just a stab in the dark, as I don't see what that has to do with this problem. I am thinking about setting my motherboard to defualts by opening up the case, etc. but I don't think that will do anything.

I have an Asus W3H00V (which came with the Mobility Radeon X600) that I use for word processing, internet, and watching videos, though never really use it for gaming. After about a couple of months of use, my laptop suddenly always hangs with a blue screen popping up saying that there's an infinite loop problem that's caused by the file ati2dvag.dll, especially when watching videos. I've tried uninstalling and installing Windows XP (w/ sp2) four times and also uninstalling and installing the ATI drivers that came with my computer numerous times but nothing seems to work. I can't get any work done on my computer because an error window also always pop up and hangs my computer very frequently. I've tried searching for solutions in the internet but none seems to work.

I was incredibly bored and I downloaded an old DOS VGA version of The Oregon Trail from the-underdogs. I used VDMsound to run it, and everything seemed to work alright until i got sick of the game and tried to quit. It locked up, i used ctrl-alt-del a few times, got impatient and stupidly switched off the computer just as i was being dumped back to windows. When i turned the computer back on, i was given the "safe mode" prompt, so i chose to start in safe mode. It then showed that list of system files(?) it was loading until it gets to "d347bus.sys" and asks if i want to press escape to skip loading it. Regardless of whether i press esc or not, it moves on to "SPTD.sys" and asks the same question. After i press escape (or not), i get a black screen, then the computer restarts again back to the safe mode prompt. If i try to "start windows normally" i get to the Windows XP loading screen, the progress bar moves a bit then the whole thing restarts again. Safe mode with command prompt, safe mode with networking, last known good configuration, none of these work, they all result in this maddening infinite loop.

My desktop is stuck on an infinite startup loop, I can see the standards Windows starting screen then there is a quick BSOD flash and the computer restarts and does the same thing - lucky I have a spare old laptop which will allow me to jump onto this site. Safe mode options do not work I tried the Windows recovery console - typing 'R' booting from the CD but then I get stuck at the console black screen not knowing what DOS commands I should be pushing. I tried goign the other way and choosing to install XP but then I get a message saying C: isn;t configured and will need to format to continue.

My PC has old configuration, the Max Power Supply can be only up to 350W. You know that every parts of the PC, either external or internal hardware will consume power. What I would like to know is that, what would happen to my PC if the total power consumption exceeds the MAXIMUM VALUE of the power supply unit.

The Memory has been tested by PCClub and has passed the test this memory is new and fresh so nothing is wrong with the memory.What im thinking is that its the power supply because i didn't get the Power Supply my friend got the power supply at the Thirft Store (the name of it is what it is Thirft Store) now i didnt think it was messed up because it was in package and all wraped.I have some pictures but NOTE: The Pictures are when i was useing the CPU from a Compaq Presario so dont pay anything to that.

computer for a few days you would press the start button on the tower and it wouldn't start right away but then after a few sec would come on. Yester day I tried it twice I pressed the start button on the tower and you could hear the power supply try to start but would die and the computer would not come on. so about the thired time press the button and nothing, would even try to start. I figured it was the power supply. I put a tester on the power supplyh and it said it was bad, so I bought a brand new one put it in and it still would n't do anything just dead.I tested the new one and my tester sasid it was bad, I changed it for another one and the store I bought the 1st one from tested the 1st one and there tester showed it was good, so my tester must not be working.

I brought a 400watt power supply from eBay it has the sticker on the side that lists the power but i want to make sure that it can actually give 400watts because i know that it isn't too hard to change the sticker or change the case and replace the internals with the internals of a 250-300 watt PSU are there any tools that i can use to check if the power supply can give 400 watts? it is a PSU made by ultra.

I have been using a "Raidmax RD-350W" power supply with a 20-pin connector to the motherboard. When i bought a new power supply it had a 24-pin connector to the motherboard. Here are a few questions since I know nothing about PSs. 1. Is there a designation (besides just manufacture preference) between 20 & 24-pin connectors to the motherboard (i.e. Pentium vs. AMD.I use AMD)? 2. Can I just buy a connector from the 24-pin connector from the PS to the 20-pin connector on my motherboard and not adversely affect my computer's power.

I last night I turned off my computer for the night and this morning it wouldn't turn on. I checked the power cord and the power strip and everything looks fine. It looks like I have to replace the power supply unless someone has other suggestions. My question is, since I may have to replace my power supply, is it safe to replace it with one that is more than twice the wattage of the one that's in there now.

I recently put together a new computer. I have used it for about a week now, today I got home and my computer won't turn on. I am guessing bad power supply but wanted to check if it might be something else.
The mother board that I have is a Biostar K8NHA GRAND Socket 754 ATX Motherboard, DDR400, 1394, SATA RAID, 6ch Audio & GB LAN

I have just upgraded one of my old Windows 98SE computers to XP Pro. The installation went well.But, for some reason now after I shutdown the computer in order for me to turn it back on I have to unplug it from the power supply and then plug it back in. Before i upgraded the computer I was already having a shutdown problem with Windows 98SE.Every time that I would shutdown, it would restart on its own.I tried to trouble shoot the problem.I even downloaded a patch from the Microsoft Website but it still didn't work.So i figured if i upgraded it to XP it would solve the problem, but I ended up with a different problem.

I have a problem I have a new system installed Windows XP professional. Everything was ok till yesterday. I just have a few more things to install and I have the computer plugged into the 4 plug UPS so if the power goes down the computer has 5 minutes to shut down. Well the hydro went off yesterday for a few seconds and all of the other computers came back up but the new one. It was booting into Windows got to the Windows logo and the bar going across loading then after 10 minutes still sat there. I decided to re-boot to see what was wrong as I am a computer tech. Nothing so I went into safe mode that was fine got out of there same thing logo looks like it was starting nothing. I did put in the Windows XP disk thinking to just do a repair still the same thing. I get the Windows screen like it is loading nothing. Go back to safe mode and here is what it says and there is no disk at all in the drive. Can not run setup from Safe Mode rebooting computer.

This is an IBM think center with XP Pro. Symptons are random shutdowns and restarts, and constant freezeups. I checked the power supply and it smelled like it was burnt so I changed it. I replaced the HD with a new 40 gig Hard Disk and when I went to load OS it got as far as "checking system configuration and then it freezes. I cant format or reload OS.

My computer starts up normally.It always just autologs on since I'm the only one using my windows xp computer. However, before anything can be displayed it immediatley logs off to the logon screen. I click my username and start the login process (i have no password and before even switching to my wallpaper or anything it says stuff like logging out and saving your settings.
I tried booting in safe mode too and the same infinite logon loop occured to, even with the default administrator account. The last thing I remember doing before this happened is I was playing City of Heroes when it crashed forcing me to restart my computer. This happens occasionally in certain programs but I've never had anything like this happen before. I tried unplugging my keyboard, mouse, usb devices, ethernet cable, no luck. Intel Pentium 4 1.7 ghz Geforce 5600 FX 256 mb windows xp home service pack 1, in case any of that matters

I have a question regarding my PC and some problems that I have been experiencing, which I think are related to my power supply.
First off, my PC will not recognize my iPod Shuffle. When I first purchased the Shuffle, everything worked fine, however one day when I went to plug it into my USB port, nothing happened and the orange light on the iPod flashed. I tried all the USB ports, including the ones on the back of the machine to no avail. This is not a problem on other people's machines, where XP is able to recognize the external device.
Also, whenever I go to shut down my computer, the light on the front of the tower is on and the fan is running. It is like the computer is not even shut down. I have to manually turn off the power strip everytime I want to shut my computer off. Also, "Stand by" is not an option on the XP menu.
I've been told this is a power supply issue. Anyone have any other ideas?

PC is XP SP3..On boot up the PC won't allow me to press delete or f8 to enter set up.It then just goes to the "We apologize page" but I can't use my keyboard to select safe mode or last good configuration.(I have switched to an old non usb PS keyboard but this won't work either.)It then counts down to 0, flashes blue for a split second then shuts down and restarts on its own. This is just looping over and over.I cannot use the keyboard to f10 for recover either. Occasionally it starts up and it gives me the "Disk Boot Failure" page.

I've done something and not only do I not know what I did, but how on earth to get around it. I've been working on a Dell system and have gotten rid of several games, programs described as spyware or adware when I googled them and that's about all. Now, however, the system simply won't boot up. It just keeps looping after the Dell screen comes up. I tried booting from a boot disk from drive A: but can't even get in that way. Does anyone have any ideas what I might have done and?moreover?how to get in to the darn thing so I can fix it?
