Is it possible to install a regular power supply unit (I have an Antec 380 Watt, 80 plus bronze I bought, and kept from 7 years ago in 2010) to install into my Sony VAIO PCV-RX850 Desktop computer, (bought in 2003)? The motherboard supports PCI interface for the power supply unit, and internal hard disk drive, and an nVidia GeForce FX 5200 video card that was installed later in November 2007; interface is PCI. The operating system was upgraded from Windows XP; now running on Windows 7 Home. System memory (RAM) is now at 1 GB (originally it was 512 MB with Windows XP); and another 3rd DDR module of 512 MB can be installed, too; if I manage to find this module of 512 MB, because this capacity is very scarce. I had the 3rd DDR memory module of 512 MB, but I discovered that it was defective; anyhow that's another long story. If I cannot install an ATX power supply unit, I realize I should, or must, buy a sound card; because the original PSU has a speaker DC jack. No micro ATX PSU has such a jack at the back of the PSU to connect the speaker power cable; from what I've noticed from computer, electronic stores from the Internet. Furthermore, micro ATX power supplies are rare; most PSUs are of the popular form factor of ATX. Present internal hard drive is a Maxtor 200 GB HDD (late 2005), upgraded from a Seagate 80 GB HDD (of 2003 that I now use for back up that I installed in a fine metal enclosure, and it still works).

I have opened my Sony VAIO desktop, now operating on Window 7 Home, twice; then to re-connect a loose cable. Now it won't boot up. Furthermore, I was careful of static electricity when I opened the computer case; I wore an anti-static wrist strap. However, to me it sounded as if the noise came from the PSU. Therefore, after going on the Internet, and checking out YouTube videos and explanations that the culprit of the noise was the PSU, I was certain that it was actually the PSU. Therefore, I was sure the grinding, whirring noise was from the PSU, not the hard drive. From research on YouTube I strongly suspected there was something wrong with the PSU, not the HDD. However, as I carefully opened up the PSU, the fan revolved freely, and without noise. Then I opened up the computer case again because of an error before the Start screen after the first apparent examination; for there was no actual repair done. Therefore, after I opened the computer case I re-attached a couple of loose cables. Now that everything is tightly connected, this computer cannot turn on! Anyway, I'd like to add that the internal design of the case by Sony is not that great; how these technicians managed to drag the P4 cable into the power connector to attach to the CD-RW drive is beyond me! It took me an aggravating, and many careful attempts of pulling, and adjusting the wires; and I finally got to connect the cable after what felt like a half hour at least! What an accomplishment! Then to my dismay, and discouragement it did not work! Or, is it the power switch that is defective, or disconnected? Any advice is greatly appreciated. Thank you for your advice.

Sincerely,

If you want exactly that PC to work, ebay is your friend for parts. Liekly you can one a VAIO of that generation to donate MB or Power supply or disk for $50 including shipping.

IF you want any PC, there are better, cheaper PCs out there. A new win10 laptop is $300 at best buy. Tons of used win10 core2 refurb desktops for $100-$150.

If you want to debug your PC rather than just guess follow this sticky. It is designed for new builds, but will let you debug an existing dead system. http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems

(basically get the system to just eh MB, CPU, CPU fan and Power Supply. No other wires attached to the Power supply or the MB. Power up. Your VIAO will beep...

Your VIAO will beep "no memory" if it is working and will sit dead if it is not. If it beeps "no memory" then power off, install one dimm, and see if it now works. If it does not beep "no memory" then replace you choice of MB or Power supply.

Good luck.

Do be very very careful here. The caps in a PSU can shock you even when unplugged. "..However, as I carefully opened up the PSU,.." most people just look in the holes in the PSU to see what the fan is doing. I've never opened a PSU, but I've used compressed air ($7 / can at staples) to get the dust out fairly often.

Thank you very much, tsnor for your sound, safe advise of repairing a PSU. I now have given my Sony VAIO desktop computer to a Computer store that also specializes in repairs, and upgrades (not the typical computer, electronics big box store that has several other electronics).
