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
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.
View 5 Replies View RelatedI 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.
View 2 Replies View RelatedMy 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.

View 1 Replies View RelatedI 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.
View 6 Replies View RelatedI 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.

View 1 Replies View RelatedYesterday, I was half way through burning an ISO file to disc using [program name deleted my mod.] (have used this many times previously without a problem), when the computer froze. Nothing worked (mouse, keyboard) and the only thing I could do was turn it off at the power button. I left it for 10 minutes, started the computer up again and the (black) screen came up giving 'you need to reboot' and 'insert a bootable disc' messages. I inserted my Windows XP disc as it's the only one I have and don't have a bootable disc, and after while I was given 3 options - one was to repair, one was to escape and I can't remember what the 3rd one was. Anyway I pressed repair and after a minute or two it said it couldn't find the hard drive (or disc) so it was unable to repair and the only thing I could do was quit. After leaving the computer off for a period of time, I switched it back on and it came up with the disc scan screen details and went through the process quickly and it said one of the sectors had been repaired and it was 'back to normal' after that.
The computer is 4 years old (Intel Pentium 4/3.2gHz/1GB RAM/Hard Drive 149GB) and I've had intermittent problems with the CPU overheating due to dust etc which I've cleaned out from time to time (as you do) and all has been well.So, in total this has happened 3 times in 24 hours but on the other two occasions when it froze, after turning it off and leaving it for a couple of minutes, it came back again as normal. The computer seems OK when it's not under load (using the internet/emails/typing documents/photo editing) but the first time you ask it a big question (e.g. copy or convert a disc) it will freeze. Is this a CPU, hard drive or motherboard problem or any other ideas please.
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.

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.

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.

I couldn't turn it back on at all. I've tried hitting the power button and unplugging the computer. Nothing works. There is a green light near the power cord in the back blinking and that's it. I've tried unplugging all peripherals before plugging the power back in. I've also tried unplugging it and pressing the power button a few times before plugging it back in. I just can't get it to turn back on.

View 9 Replies View RelatedI 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?
I was unable to turn my Toshiba laptop on this morning. It was working fine last night when I logged off. The power and battery lights are on and I've checked all connections but still no luck.
View 8 Replies View Relatedwhen I press the power button (and I've tried turning it on off of the battery, battery and outlet power, and just the outlet power), the light turns on, I can hear the regular whirring, but then the power button starts to flash, as if it's in standby mode? I've tried pushing a few buttons on the keyboard, tried pushing the escape button, tried pressing even the wireless LAN button that's at the top... nothing. When I press the power button, nothing happens unless I hold it down for five seconds, then it just turns itself off again.

View 8 Replies View RelatedI downloaded some windows updates but not all of them installed. When I go to Turn Off Computer, the "Turn Off" button has changed, indicating that when I hit it, it will install the updates. There's also a field I can click which will Turn Off without installing the updates. When I click the Turn Off buttion, it attempts to install two updates. It doesn't appear to be successful. Every time I Turn Off Computer it apparently tries to install the same two updates. I can reboot and do this over and over and they don't "take".There's nothing in Event Viewer to indicate what's going on. I couldn't find any installation logs though I'm not sure where to look.

First grab XP PowerToys from microsoft.com Once installed right click then check: task bar > toolbars > Desktop ManagerYou may now view up to four new desktops. I prefer not to have "Shared Desktops" on as it reminds me more of linux (and is cleaner).Now you may hide the buttons etc. and use Windows key + 1-4 to switch between desktops and Windows key + v to preview.
