New PSU-PC not starting. CPU-power-adapter
Had a possible short circuit on my Dualcore Asrock AliveDual eSata2.
Only recognized it later when onboard-connector was looking like burnt.
I didnt change PSU.
It was only later when i had(or thought i had) a soldering-problem on openly laying MOBO. its sitting on sockets, maybe i had not enough of them and was bent. to make it short now: After changing Videocard(couldnt get replacement fan with the right plug) it was overheating- around 50° C and more. couldnt yet add fan since lacking adapter. Sometimes i had short screen-blackouts(driver-error announced) never had that beforehand.
all of a sudden PC shut down. maybe i had set a temperature limit.
i changed PSU(Corsair VS650) but couldnt use it since no 4 pin-processor-power-cable.
now i have an adapter attached to one of the multiple Molex.
Is that correct? can i attach the adapter to any of the Molex or Sata-Plugs?
I changed also the MOBO. Yes the one with short circuit i removed. There i am about to exchange the burnt 4pin-connector.
Also exchange the processor. But dont know if its working.
Also dont know if that MOBO is working.
I must also test new Memory. by removing one pair of the 4x4 GB ram 16 B max. installed 6 months ago.
Yes will get also a new MOBO. Have 3 in total.
a) with burnt 4pin-connector(Processor-power) No1
b) working one until recently No2
c) No3 unknown if working.
Yes a very efficient processor-cooler was attached.
Was quite hot recent days. and i didnt use an external big fan.
MOBO naked outside case, all chips have fans except new videocard. item which had highest temp. 50-54°C speedfan used.
Will now try with other MOBO which was working properly.
on the bad one i did soldering on USB and main MOBO-power-connector. see other thread. Power shut down when pressing MOBO down near that location. No i have an additional large socket there. Sockets for Airflow.
Yes will get another MOBO-copy.
When changing processor and MOBO I allowed not adding thermal compound only to check if pc is starting.
It was starting and stayed but was like pumping. floppy-light was blinking. maybe really Processor-power-connector. i will switch to a different MOLEX.
can i measure currency?
Thanks a lot
Actual(the one i am now surfing with) PCs AGP-Videocard not supporting 1920 x 1080. very annoying. Winxp
Ga-7N400 Pro 2- at every boot harddisk(IDE) fail-Elko defective?
Sicne every time after i exchanged battery by a new one on boot its telling: harddisk fail. Must the ELKO be exchanged?
I will now leave the PSU on and check. i will resolder eventually cold soldering point of battery-case. good MOBO is laying outside case.
Reactivated old MOBO and Internet access with WLAN
Sorry for complicated thread but its about two PCS. newer ASROCK alive dual esata2(dualcore) and Gigabyte 7N400Pro2 Ver.2.0(have also ver. 1.0). Have multiple MOBOs.
Will get one more ASROCK today.
SUCCESS after almost 3 weeks struggling with multiple MOBOs and testing equipment. one of the GAs even had cmos-clear pins removed.
There were multiple defective parts. I am now on the very first one. its seem i killed PCI-slots. and LAN seems also not to work thats why i am on WLAN-stick now.
The GA has now a main problem which others confirmed. If changing drives -could only make IDE-drive run-one must remove battery for 30 seconds other wise cmos cannot hold specifications. it seems capicitors must be replaced. And running SATA-drive not working anymore. on other than the actual MOBO i could see ITE-raid and onboard-Raid-drivers in cmos. will ask the experts in Gigybyte-forum of UK.
This GA-MOBO is quite slow even on very quick internet.
high temperatures slowed down PC-Gigabyte 7N400Pro2
could cut down temperatures of CPU and GPU down to 45 and 33° C. CPU was up to 54. Motherboard monitor showing CPU and other undefined temp.and Speedfan GPU.
Would like to see also HDD-temperature other than in Bios. was 44° C right after start.
have now a cooler box from freezer ontop of it with a water-absorbing layer inbetween.
could not make Speedfan be loaded during start.
Was discussed earlier. didnt yet find the trigger. despice a lot of advises. Winxp- non SSE-processor. some tools are not working.
Unbelievable surprise: other bootdrive accessible as slave
On old Gigabyte 7N400 pro 2-actually my very first one which has some defective functions-i could "revive" a 320HDD which was on when stupid electrician cut the power despite me telling PC was on... he didnt know german...and didnt tell me.
1. i had troubles accessing drives when switching from one to the other. had to remove battery and wait 30 min.
Tried everything i knew to make it bootable again. fail-it will not be recognized anymore at start.
i have set now scsi and raid-setting base and ata. will try with HD0.
So i decided to check if i can access data when set as slave. WORKS!
It seems i have really a capacitors failure. maybe had power off but battery/capacitor could not hold data again.
I will try to get a fresh working MOBO.
Second Asrock alive Dual eSata 2 is on the way to work on tuesday.
Since i had power-shutdown when i touched the board-earthing-cable on new PS-connector( 3 phases) i switched the earthing cable to the heating. both pcs on the same cable. could be the problem was due to the fact that i didnt use a screw to fix the cable. it was laying loose around the opening.
I will not risk my only booting IDE-drive on GA-7N400 Pro2 on a next power-shutdown. i thought it earthing would compensat electrostatic discharge.
SUCCESS-UNBELIEVABLE- WIN7-64-PC working again
Its unbelievable: After long 5 weeks struggling with two nonworking PCS, Gigabyte 7N400 Pro2 and Asrock Alive Dual eSata2, i could finally find the main problem of today: pc starting but no image.
I know earlier i replaced multiple Cmos-Battery-holders. topcontact was nonworking. repaired it but i will replace it.
During start played with screen-switch, pulling it multiple times until start-screen was visible!
I bought two new PSU:
1. Corsair VS650
was starting but produced pulsing-like behaviour on the fans and led-light(floppy). maybe defective old PSU "killed" MOBO. and halfdefective MOBO killed PSU.
was using molex-4-pin-adapter since pc-shop-expert showed me how to seperate 4+4-pin-connector......
Will not check PSU again with working PC since there i am using modular
Corsair CX 650M.
I tested three MOBO Asrock Alive Dual eSata2. and also the processor i received with new used board without success.
Since i have 2x2 mb Ram i will build a third PC for checking VS650.
Hurra for my main PC.
Capacitor seems not charged-cannot hold Cmos-data
Maybe i must run PC for 10 hours? or can i only leave only switch on after pc-shut-down? is that enough to charge capacitor since it cannot hold cmos-data. fresh battery. PC was ON for at least 6 hrs. didnt help.
maybe best replacing battery-holder. maybe soldering not perfect enough
small steps with great success
As you know i am writing about my adventures with my two old PCs which refused working over 5 weeks ago.
1. Gigabyte Ga-7N400 Pro 2. Winxp
2. Asrock Alive Dual eSata2. Winxp and Win7-63
Both have Sata and IDE.
the IDE 320gb-drive from GA-PC which was not recognized anymore after an external power-shut-down(by an Idiot) was recognized on Asrock but hanged during boot.
3. GA-PC now is holding Cmos-data when PSU is shut down but cable not removed. most probably capacitor(s) is now revived and charged.
Next task is reviving the IDE-320gb- drive on GA by flashing BIOS. Was succesful earlier with this method. But i will no use default last Bios but a newly programmed one.There is a big discussion about bad BIOS-since SATA-drives are not recognized anymore -. flashtool had also been replaced beside new Bios(two versions).
I am working now on newer PC since navigating on internet is slow/Firefox is slow on old PC. Will prepare micro-SD-adapter as Flashstick. SDformatter 5.0(avoid earlier version 4) is needed to format and unlock. further instructions google BIOS-flashing.
I will discuss flashing in Gigabyte-forum.
capacitors with bulging tops
giving away for free sind capcitors are dying- tops not flat..... from an ad:
"Verschenke ein ALiveDual-eSata2 von Asrock. Das Board funktioniert, hat aber Kondensatoren mit gewölbten Deckeln, deswegen wird es verschenkt."
I will ask a friend to replaced all identical capacitors on one of my additional MOBOS and setup a third PC. i counted about 20. they have + and - poles.
replacing capacitors-how to do
i will not DIM. but let it be done by a solding expert.
Wonder happened: Could shut down PSU without having to enter Cmos to adjust settings
After a normal start in the morning sometimes hdd cannot boot, is hanging right at start. shut down and restart normally help. this time i shut down PSU- and after 5 seconds restarted. And could boot normall. What a surprise-for the first time after the repair! It seems patience is giving Luck.
Beforehand i always had to enter cmos to adjust settings. remember: its on the newer ASROCK AliveDual eSata2. on much older(2004, yes actually the very first copy is installed)Gigabyte GA-7N400 Pro 2 i could form capacitors to allow shutter down PSU. We will see when i control after some time.
sometimes PC is not starting or i will not see systemstart
wierd is sometimes pc-start is not visible onscreen. Maybe time to replace 27" samsung-screen.
since sometimes i must push-pull screen button to make image visible during start.
last time i made a reset and pc made a systemrepair. i allowed systemrecovery(systemwiederherstellung).
Cold soldering points the reason for MOBO_Blackouts!
I must shorten a bit my tragedy with one of the two mainboard-system Winxp and Winxp/Win7-MOBOs.
On Ga-7N400 Pro2 i couldnt make my sata-drives run again. didnt know how to do and didnt know if on my first GA-MOBO(have multiples) sata is also defective like onboard-lan and pci-slots.
first the electrician killed one of my two ide-drives. and i myself made the only one not running anymore. its on a loop during start. first it said system-file is damaged or similar. Winxp Windows\system32\config\system
doesnt it have an ending? in need i tried to copy the system.save-file ending removed. without success. later when sata-drive on second perfectly running again-duplicate-MOBO was working i tried to attach as second drive to make it running again. earlier i succeeded with that technique. but not in this situation. iots a software-problems. any idea?
2. Later when i was at dead end i switched the board but it didnt start!
then i remembered the idea of replacing poor capacitors(see old thread about delivery of bad material around 2004 just when i bought it.
since no new capacitors around the only cure could be resoldering the capacitors and the three electric soils. cannot upload images.
Before swithing MOBO i resoldered then and removed battery(for 30 seconds. not one word in manual when cmos clear is needed.
only could now run my sata-drives. which i had to clean and cure for stable running. I am actually on chrome. firefox 48 is the latest running with non-sse 2 processor but its crashing all the time so i had to switch browser.
when situation is better i will come again and open a new thread since new findings all around the universal sata-ide- Raid-Boards.
Non SSE2-Processor-Winxp-PCs-Firefox 45.3.0 ESR is latest good working

if FF 48.0.2 is installed Firefox will crash very often with 45 only from time to time.
on FF 48 videos on FB should run.
if one could not update to FF 48 one can directly downgrade to the right FF 45.3.0 ESR.
Capacitor plague -the reason for dead/dying PCS
Rubycon Capacitors not Rubiyoon
Great News. Found a mistake-and PSU may be shut down
Had been running my old GA-7N400 Pro2 for quite long time. its 18 months since all this here started.
1-The right browsers for old Winxp-PCs(even slowest are running on internet)
meanwhile found the right browsers for my SSE(not SSE)-Processor-PC.
Here is the second part of a very long discussion. yes everything in one thread(2 parts).
One needs a lot of breath and patience to understand.
start in page one of part 1.
2. Had often crashes with all browsers mentioned above in msfn.org. dependent where i was surfing.
Palemoon Newmoon 27SSE, KMeleon, Firefox 45 ESR
yesterday i tested memory 3x 1mb Ram. i exchange them. errors with all of them in slot 1.
No they are not defective. Memory slot 1 is dead or ill.
so i am now running with 2 x 1mb ram. explorer-crashes may happen but not browsers.
Next is examining the services. Yes in know the other workaouround if slow winxp etc.
3. I still have slow internet despite the memory-cure. only 30Mbps
Download. should be 1000. havent yet found out why. cannot install mobile router on winxp. or is one working?
we will see wnen i have new laptop i7.
see my new thread.
4. Big surprise after i cleaned pc and replacedhermal compound. PSU was shot down.
Capacitor can hold cmos-setup-content. only dont know for how long without electricity. during this PSU in standby capacitor for cmos-setup-backup had been formed(hope its the right term) reactivated.
Was a problem leading to non-total-shut down of PSU. will now test if this is not temporarily. already had a 3months only successstory on this behalf.
