Probleem siis selline, et D601 led põleb kui arvuti käivitan pidevalt, kuid mitte alati.

- Kui tuli põlema ei lähe, siis saab mängida mänge ja töötab ilma probleemideta.
- Kui led põleb (D601), siis arvuti töötab, netis saab käia, mussi kuulata jne, aga 3D applikatsiooni käivitades arvuti lukustub, heli jääb loopi ja ventilaatorid hakkavad tõsiselt tööle kõik. Ainus variant on restart lootes et LED ei lähe põlema.

Andmed:

psu: FortronBlue Storm 500W
cpu: Intel Core 2 Duo E8400, 3000 MHz (9 x 333)
ram: A-Data EXTREME DDR2 800+ 2GB (2 tk)
mobo: Asus P5Q, LGA775, (3 PCI, 2 PCI-E x1, 1 PCI-E x16, p45 chipset, Audio, Gigabit LAN, IEEE-1394)
video: ati HD 4870 (club3d) 512mb

The first 4 months were all fine. No issues at all, the system ran completely stable with a 500 MHz OC on the CPU and a 25 MHz OC on the 4870 (75 MHz total OC since the card already had a 50 MHz factory OC). I folded on this 4870 for several days at a time without any errors. Then I ran Furmark as a stress test. I had started worrying about my graphics card because it had a PCS+ 3rd party cooler on it. These have great GPU temps (58C while folding @ 30 % fan) but the VRM temps get up to 110 C on it. When I ran the Furmark stress test it triggered the second LED on the HD 4870 to turn on. This one indicates a critical core power fault, my system crashed about a second after this light went on. VRM temps shoot up to 150 C in about 20 seconds I didn't have time to stop it.

On reboot the light was gone, and didn't come back even when the 4870 was folding. I forgot about it (Didn't run Furmark again). Then, about a month later the light came back at power on. I shut it off, turning it on again the light was gone. This continued for about 2 months. Rebooting or changing a BIOS option that required a cold reboot, got rid of it most of the time. With the LED on the system runs perfectly stable as long as no 3D work is being done. It can play flash games, watch a movie, desktop works fine, etc... but try playing a game an it crashes. The interesting thing is I accidentally discovered folding runs perfectly fine with the light on but works about 10 times slower. The CPU can also run at 100% and the system is stable.

Two weeks ago the light began being triggered just by trying to run 3D programs, (Instead of the usual on or off at start). Most of the time this results in system lock up but sometimes I can get task manager up and end the program. Now the weird thing is sometimes running 3D programs won't trigger the light and it works fine. (I'm folding right now, perfectly stable, but two reboots ago folding triggered the light).

If I listen closely, when the light turns on there is an audible high pitched noise that beings, very quiet, but much like the noise of an old CRT television.

So the question is, is my PSU beginning to fail to supply enough power to the HD 4870. The HD 4870 works perfectly fine without the light on. Or is the HD 4870 failing.

Do you think the 4870 is still alright?

What I have tried to fix the problem:

Removed all OC's
Un-plug Re-plug PCI-E connectors
Re-sit the graphics card in the PCI-E x16 slot
Clean the cards fan + Heatsink for dust (Wild guess)

None have worked.

Ilmselt PCI-Ex toitejuhe jamab. Kui singlerail PSU siis võid voolu võtta molexist. Kui kaarti tolmust pidevalt puhastad suruõhuga siis need juhtmed ei kannata sisse ja välja tirimist. Uuestpeast juhtmed kõvasti kinnni ja peale aastat 3x-4x sangutamist hakkab jamama.

Kui sõbra arvutis täpselt sama jama siis pakun ,et 1) kaardi toiteahel kuumeneb üle ja kaart üritab klokid 2d-s hoida. 2) kaart hakkab lihtsalt omadega kahjuks otsa saama. Remontida vaevalt et saab ja kui garantiid ei ole siis ilmselt kurvad lood. Kuigi ekstremistid vahest proovivad selliseid kaarte ahjus küpsetada või viskavad mõneks päevaks sügavkülma hermeetilises kotis, et joote ühendusi parandada.
Ära ise neid asju tegema hakka kui kogemus ja teadmised puuduvad!

kert06, 6870 on hea kaart aga räägi parem mis resolutsiooniga mängid ja milleks veel kasutad? pikemas perspektiivis vast 6950 kõige mõttekam kuna annab 6970-ks fläshida või siis lihtsalt kellad samale tasemele klokkida. Endal sama probleem varsti ees seismas kas 6870 või 6950 aga kuna mängin 1280x1024 resoga enivei, siis 6870 ratsionaalsem.

no siis kellad lihtsalt enamvähem samale tasemele... erilist vahet pole

kert06, Seleta mis krigin tuleb, kui krõps, krõps kuumenedes tuleb siis on seal termopasta kuivanud ära.

kert06, ma arvan, et tee HV ostuabi/hinnapäring alafoorumisse teema ning pane oma praegune/tulevane arvuti konf kirja ning anna hinnapiir ning sulle soovitatakse parimaid variante
