The switch mode power supply in the desktop computer has failed. Most likely the capacitors in the power has exploded.
You need to open the desktop computer and remove the old power supply and replace it with a new one. Take the old power supply with you to your friendly computer shop and get a replacement power supply with the same wattage or greater wattage.
the power supply wattage rating is MAX wattage, not constant wattage. the power supply only outputs the amount of power that the rest of the computer calls for, and no more. if yor computer only needs 200 watts, that is all that will be sent from the power supply; even if it has a max rating of 600 watts, it will only send the amount of watts which your computer calls for.
1) Computer unplugged from power, computer case open. TOUCH the metal frame BEFORE you reach inside. Your body carries Static electricity. Static will fry out computer hardware components. You won't see it, or feel it.
Computer unplugged from power, you are safe. Touch the metal frame Before reaching inside, your computer is safe.
Should you get up for any reason, walk away, then return, Touch the metal frame again)
You either have a 375 Watt, or a 425 Watt power supply. I would recommend a power supply with more Wattage, and more Amp's on the 12 Volt power rail.
The Dell XPS 420 comes with an Intel Core2 Duo processor, or an Intel Core2 Extreme processor.
These puppy's can use a lot of power when gamin', or other intense programs are being used.
The Nvidia GeForce 8800 Series of graphics cards offered, use a lot of power when maxed out.
The motherboard with the Intel X38 motherboard chipset, uses a lot of power.
I would recommend a 600 watt power supply for a replacement.
My recommendation would be an OCZ StealthXStream 600W
Why?
1) If the temperature of this PSU is kept under 118 degrees Fahrenheit, the PSU can put out 728.8 Watts reliably. (47.9 degrees Celsuis)
2) It has Four - 12 Volt power rails. EACH power rail can handle 18 Amps. That's a total of 72 Amps!
3) It has all the power cables you'll need.
A) 20 + 4-pin ATX motherboard power cable B) 8-pin 12 Volt power cable (8-pin EPS) C) 4-pin ATX power cable D) SATA power cables [ 3 ] E) Peripheral power cables, (4-pin Molex) [ 6 ] F) 6-pin PCI power cables. [ 2 ]
There are 5 versions of this model http://global.msi.com.tw/index.php?... They have either 5 or 6 PCI slots. Find the version number - beside the model number Note the SiS main chipset numbers (one may be under a heatsink)
MS-6547 Ver 1.0 a.k.a. 645 Ultra - ATX, 5 PCI slots http://global.msi.com.tw/index.php?... SIS® 645 Open Architecture DDR333 Chipset SIS® 961 MuTIOL® Media I/O Chipset
MS-6547 Ver 2.1 a.k.a. 645 Ultra-C - ATX, 6 PCI slots http://global.msi.com.tw/index.php?... SIS® 645 Open Architecture DDR333 Chipset SIS® 961B MuTIOL® Media I/O Chipset
OK, Here you are . Your present card ,8500GTdraws approximately 40 watts. Your proposed card draws approximately 150 watts according to a review I just read on it. A 400 watt is not very much and if you get close to maxing out you run the risk of a low voltage problem which could and will burn out compoinents.
I would not do it.
Also , if you upgrade power supply, know that the wattage given is usually peak , not operating wattage which can be as much as 10 or more percent less. Go for at least 600.
Hello rc53_61, If you look at the back of your old power supply you should be able to find the information you need (if you are going to replace the current power supply with the same one). The best place to find an exact power supply is visiting the manufacturer of your computer system for example: dell, hp, compaq, etc. You can replace a power supply rather easily, the only things you need to make sure is that the plug connection is compatible with the one on your motherboard and the power supply rating is the same or even a bit higher for wattage. Check the following links to find some good quality power supplies at a reasonable rate. These sites will help you with compatibility also by putting in your motherboard information. Let me know if you need further assistance.
