I have a Radeon All-in-Wonder 256mb agp card and an Acer al1916 lcd monitor. The problem I'm having is if I have to restart for any reason, ie. downloads, updates, etc. , the system will shut down but the monitor says no signal. The only way that I can get the monitor to work correctly is to reset my CMOS. Then it starts normally, all is good, except I have to reset the date again. I don't know a whole lot about this video card. I noticed that there is a plug on the card (4 pins) near the top. It is labelled JU10. Any ideas what it's for? and will it cure my problem. thanks

Brief diagnosis and practical checklist based on the posts from , and .

When video only returns after clearing CMOS and the clock/date must be re-set, the simplest and most common root cause is a failing CMOS battery (CR2032) or BIOS settings not being saved. Clearing CMOS temporarily restores defaults that let the card initialize; a weak battery lets settings (and the real-time clock) drop between power cycles. That said, intermittent “no display on reboot” can also come from AGP/card initialization on warm boots, PSU or card faults, or BIOS/driver conflicts.

Quick troubleshooting (do these in order):

  • Observe whether the BIOS/POST screen appears before Windows loads. POST visible → likely driver/OS; no POST → hardware/firmware.
  • Try a full cold power cycle (power off, unplug PSU, wait ~30s) vs a warm reboot. Differences point toward AGP re-init issues.
  • Replace the motherboard coin cell (CR2032) and re-enter BIOS time/settings. This is inexpensive and often resolves symptoms where clearing CMOS temporarily helps.
  • Reseat the AGP card, clean contacts, verify retention clip, and inspect the card for damaged or bulging caps.
  • In BIOS set Primary Display / Init Display First explicitly to AGP (or disable onboard video) and save.
  • Swap cables/monitor or test the card in another PC (or a known-good card in this PC) to isolate monitor vs card vs motherboard.
  • If a PSU was recently changed (see ), re-check all power connectors and test with a known-good PSU; unstable rails can cause intermittent video.
  • Note any POST beep patterns/text and consult the motherboard manual for the exact meaning.

About the four‑pin JU10 header: as noted, that small internal header is not the main video/power feed and is unlikely to “fix” the no-signal symptom. It’s typically an accessory/function header on All‑in‑Wonder boards — check the specific card/motherboard manual for its exact purpose.

If none of the above isolates the fault, next steps are: try the card in another system (or another card here), consider a BIOS update only after backing up, and prepare to replace the GPU or motherboard if the card fails elsewhere.

That header's not going to do anything for you.

Do you see ANYTHING when it boots? If the answer is no, you might want to consider purchasing a new video card, or even a power supply. If you see the BIOS POST screen, it could just be a driver issue.

I'm also getting a similiar symptom.

recently my computer died due to a bad psu so i took the entire system into the store i bought my computer at to get an exchange (i am under warranty still) for a new psu.

well they did exchange a new psu and did all the installation stuf.

now my computer will only sometimes display and run fine but nearly 80% of the time i get this audio message at the beginning - system failed mediator and also no display.

my computer specs are as followed

windows xp pro sp2
a8n-sli premium mobo
amd athlon x2 4800+ cpu
ocz gold ram 2 gig
antec true power 2.0 550w psu
500gig/2 seagate barracuda sata hhd

the system is less than a year old...and this is really driving me nuts...

i really want to get my files and personal stuff T_______T out...
