so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol! 
i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing... -
Hello guys,
I have interesting problem. My MoBo MSI running on Ryzen 7 w/o graphics just good. I swapped to Ryzen 5 5600G and on the boot I stuck with screen on picture. Enter Password. I checked BIOS setting with Ryzen 7, no security is enabled, BIOS password or TPM.
BIOS I updated to last one.
any suggestions?
And same thing for two different 5600G, and yes, MoBo supposed to support it.
Thank you... -
Hi guys,
I have a friend's Dell 3779 that came to me with severely shorted mobo. Did not manage to isolate the cause, most likely that was a bga shorted. Went for a replacement motherboard. Got one from China, apparently it's been tested prior to shipping. The mobo starts up normally but I am getting no display whatsoever.
Tried using external monitor, but being blind I am not sure if laptops goes as far as booting to Windows, a d without it I cannot get hdmi to work. Can't see boot menu options to make sure it boots to Windows. Went ahead and did a blind bios update,... -
HI I have a PC using a Corsair cx600 psu & ASRock B450 Pro4 mother board that won't power on after a shutdown (replaced a dead drive in a raid array) Not the boot drive.
With most things unplugged, including the 24 pin ATX connector, but not the ATX12v to cpu, I have +5.01V on the +5vsb pin 9 from the PSU. When I plug the 24 pin back in to the mobo, the +5vsb fluctuates between 1.1v & 1.9v.
Not sure where to go from here ?
Is the PSU at fault or is the mobo causing the problem
Look forward to any help :-)
If I plug the 24... -
Hi, everyone. First post of an actual repair. I'm a technician but a complete newbie with laptops.
So I got this Dell Inspiron to play with.
No charger, so I connected to my bench PSU.
The laptop also didn't include: hard disk (I added one of my own for testing, see below) and wireless PCB (but I doubt this could have anything to do with this particular failure).
------What it did (and didn't do)------
1) I turned it on and it powered on. Powered down in 2 seconds by itself.
2) Removed RAM, changed slot. Same...
