Dell Optiplex 755 is not boot up and flashing yellow only not power go through MB. Google search is all saying there is problem either on PSU and the mother board. I connected other PSU on Dell and found no problem and I am using that PSU on Dell PC now. I also connected the Dell PSU on other...

I bought a cheap sil3114 sata card to try as an add-in card in a motherboard that has no SATA ports. It worked OK until I tried flashing its BIOS to the latest version. The updflash.exe utility started up, but failed. Now the sil3114 card hangs the computer when booting. Seems I bricked its BIOS....

My computer case green led failed. I bought some on Ebay, but they are so bright they light up the room and obscure the other color leds. Any suggestions for a cheap source of low intensity leds in a 3mm size? Maybe Mouser, but then $1 worth of parts costs $10 to ship. If I have to spend that much...

PDC20318 chip (SATA150 TX4) PDC20319 chip (FastTrak S150 TX4) They both have 4 SATA ports. The 20319 FastTrak is RAID only, the 20318 SATA150 is hard drive and ATAPI (cdrom), but no RAID. I got a FastTrak on Ebay, it works, but the RAID BIOS takes 29k of upper memory. I load many things high,...

The PCCHIPS M811 motherboard is known to have IDE UMDA errors at ATA-100 speed. Windows XP downgrades it to ATA-66 and that works. But DOS has no way to downgrade it. BIOS can enable or disable UDMA per drive, but has no option to limit the speed. BIOS just uses the highest speed the hard drive...

Earlier, I said in the "motherboard 5v" thread: My $20 power supply is OK with a 12v motherboard. I'll match the K7S5A with a better power supply. Once I did, the K7S5A 5v was 4.90 or so. I thought everything was good, but now, after a few weeks, it's down to 4.80. Still within spec, but...

I'm planning to put together a new computer using one of the new Ryzen processors. I heard that 3600 MHz memory would provide the best performance for it, because using faster memory would require something to be slowed down to two memory cycles instead of one. Then I learned some more details:...

I'm looking at PCI IDE cards on Ebay. I see mostly Promise and Adaptec. I need one with a BIOS that can boot the drive connected to the card. Any recommendation?

This year I will probably buy a new computer, I will probably wait for the 16 core ryzen, I've wait 13 years to buy a new computer and somebody I know thinks I should wait 2 more months to get the 16 core part lol. For now I will investigate motherboards somewhat better to see which motherboard...

Wikipedia says about conventional PCI: The M66EN pin is an additional ground on 5 V PCI buses found in most PC motherboards. Cards and motherboards that do not support 66 MHz operation also ground this pin. If all participants support 66 MHz operation, a pull-up resistor on the motherboard...

Hello, I want to use the GT 1030 as main graphics card/gpu and the GT 520 as an HDMI/audio solution to try this out. So I stuck the GT 520 into the PC as well. It has two PCI express ports/slots (winfast motherboard NF4SK8AA (or similiar)) Windows 7 ultimate edition 64 bit is not detecting the...

Working on Joe Jackson, and went to transfer over some FLAC updates. Nice new HDD, (10 year old 1T Samsung I recently put in from sitting on a shelf and waiting for usage as a spare), and the USB copy transfers slow down to nothing. Locked up the hardware/controller for a unrecoverable...

I was checking out an old (LGA1366) server, and noticed that it has 9 memory slots - triple channel, 3 each. Also have a desktop (LGA2011) with 8 slots - quad channel ,2 each. So I presume then that each memory channel requires hundreds of pins, but extra slots per channel only needs a few...

The USB2 (Standard) USB (Type C) adaptor works. Halfway or as can be expected with a PC. The Type C, or much else, isn't worth much to Amazon, as I think they've a proprietary USB cord/T-C connection, where none of mine are mating with a Amazon Fire HD Tablet (except for one cord packaged and as...

I bought several of these cards, trying to find one that works with older Centos linux. Most have a PATA Molex plug to import extra power. One has a floppy disk power plug instead! And one has no extra power. Now I believe PCIe x1 is good for 10 Watts. The powerless card only has 2 USB sockets, but...

"Microsoft considering a dedicated Office key for keyboards" https://www.osnews.com/story/130160/microsoft-considering-a-dedicated-office-key-for-keyboards/ Just say no. Lynn

My legacy ECS K7S5A motherboard BIOS hardware monitor says the 5v is low. So I used a multimeter to check a USB 5v header pin, and it says 4.75v. The power supply 5v disk connector has exactly 5v, so the power supply is good. If I replace the 5v AGP card with a 3.3v card, the USB pin...
