Hi Guys, Today I turned ON my Desktop PC but to my surprise the Internet wasn't working on it (Ping was ok but no internet on browsers !) ! So I put it in Hibernate mode as-usual and went on to do my homework telling myself that I will fix the issue later. Then later on I tried to turn it ON but it wont boot up at all ! I opened the chassis and cleaned it with a blower, but to no good. I noticed that the SMPS/PSU fan is turning ON but at a slower speed than usual. The CPU fan is at stand still. : ( I have a card reader installed on the chassis which has a red led light, usually that light in ON but now it is very dim and blinking continuously. What could have went wrong with my PC ? TIA
start by taking peripherals off of it one at a time to see if something has died in one of them. I've got one here I got down to the cpu and the memory, still no boot. Monty Python's parrot ...T
Still initializing beep? Mostly mainboard or PSU.... Unplug anything external first (LAN as well)..... Check if you can enter BIOS setup. To spot the broken hardware it'd best to try anything first with a replacement PSU before you dismantle the PC part by part.
Ya Sir, I'm afraid its the PSU as I check it without any peripherals. The Mobo green LED turns on, but no startup or boot : ( But I checked the PSU itself by the green and black cable short circuit, it turned ON and its fan ran at full speed ! WTH ! Mobo Intel DG41RQ
Not a single Beep Sir ! : ( I unplug all drives and external cables but no good, no CPU fan ON, no boot. Cannot enter BIOS : ( I wish I could get a replacement PSU from somewhere..
at least we have a clue now. not the end of the world.if only manufacturers would bother to put decent caps into their products it would save their customers so much trouble.
Hmmm. It indicates that it's probably the PSU. But it also still could be the mainboard. The PSU (operation under load) might fail, anyway it still provides current..... Nowhere else than at 'no boot issues' I have encountered big surprises.... For instance my brother's PC did not boot anymore...until we've unplugged LAN.....it only boots without LAN cable! Why? I do not know...he uses WLAN now, LOL. PSU and mainboard are the most important parts of a PC and I usually buy well known brands. I use Asus boards and Corsair PSU. Since we can easily unplug all the cables from the PSU itself we can try a replacement PSU much easier than before with old PSUs... When I suspect the PSU could be the reason I borrow one from a friend first to test and only then I buy a new one....
If that PSU is 9 yrs old, I would replace it even if it worked. Those things are kinda like vegetables, and they do deteriorate with age. You should replace it just because it is 9yrs old regardless if it works or not
Sir, The Original PSU of the Desktop died rather quickly, I think the current one is the third PSU in 9 years if I count correctly.
Yeah well....if I'd follow that suggestion where would I stop replacement in advance? Target are capacitors and the mainboard has such as well... Last month I scrapped an old 486 with OS/2....anything was still working, but the scientific device which it had controlled has been scrapped as well and replaced.... Investment in a good (more expensive) PSU pays off...long term...
My solution to the problem described in post 2 is like LatinMcG's I bought 3 point of sale Optiplexes for $20 each, locally, no shipping and upgraded them with Q6600s from ebay at $20 so now I've got a system and 2 backups My old Compaq doesn't owe me anything I ran it 24/7 for 10 years ...T
