Cabling: While the specification only deals with the requirement for a motherboard 24-pin connector and a single serial ATA plug, most systems need more.For a basic unit, you can go with any power supply that has enough plugs, but if you are serious about airflow inside your computer consider a modular unit where you can use just the cables you need and no more. There are a couple of things you can do to ensure that your power supply lasts as long as you need it. One is that you provide plenty of airflow so that it doesnt overheat. The other is to clear out dust whenever possible.Ĭontent provided for informational purposes only. eBay is not affiliated with or endorsed by Bestec.I second the motion to just replace it, with a good quality PSU. Many people skimp on computer PSUs, forgetting its the heart of the system, till one fails catastrophically, and takes out their expensive CPU's, GPUs, SSDs and HDDs with it. Also many cheaper PSUs can be the cause of random crashes due to unstable, high ripple, power rails. Do yourself a favour, and invest in a good one. You'll save your PC components from a hard life, and have decent protection in case of a fault. You'd do well to read reviews of PSUs on jonnyguru before investing in it. BESTEC ATX0300D5WC REV B NEW PCĮVGA G2 series of supplies give a good "bang for buck" in the PC PSU world. Yes they're 3 times the price of the no names, but factor in how much it would be to replace your motherboard or other parts, if a cheap PSU takes them out. It is in fact an HP Pavilion but running Windows Vista. I don't have another power supply to drop in this one and I'm really looking to build a computer with much better specs and with schematics for every part so I'm a bit hesitant to pour money into an old computer. I just would like to have this one working steady.
I checked for visibly faulty capacitors and burnt components before I checked anything else. The reason I mention this resistance is that every other power rail has a much higher resistance.
I'm getting the proper voltages on every rail including the +5v rail when connected to the motherboard and powered on. I would also agree that I could be having a firmware or driver issue. The problem is I know very little about computers. I haven't gotten past learning somewhat about assembly for the NES and the last computer I was totally familiar with was TI Basic. I will definitely run stress tests on that computer.
