disque dur trop lent

Réponse de GV à ce problème de "disque trop lent" :

1. CPU insuffisante ou mauvais refroidissement
2. Carte graphique en surchauffe
3. DD inefficace, pas assez performant
4. Alimentation insuffisante ou mal régulée (500W et plus)
5. Memoire de mauvaise qualité (ou panne memoire).

Edius détecte tous ces disfonctionnements , d'autres logiciels peuvent etre plus tolérants , mais avec des risques de pertes d'images.

Il y a surement un lien avec le Hardware.
Je ne connais pas encore de remontées du problème , dans mon entourage, parmi tous ceux qui ont une machine semblable à celle décrite : ici
Et ils sont nombreux

Détails en anglais :

1. Insufficient CPU/chassis cooling
On modern systems, this will cause slowdown, as the CPUs will throttle down. If the BIOS is configured for shutdown temperature, it can cause immediate power-off.

2. Graphics card overheating (usually due to fan failure)
This can cause random noise, garbage, loss of overlay, and slowdown.

3. Failing (but not failed yet) hard drive
Usually you'll get some audible clue - like you hear the drive spin down then spin back up (this can also be a sign of a power supply issue), clicking, clacking, or screeching, but sometimes it can happen silently.
A bad drive will make the whole system pause, hang, or fail to boot.

4. Inadequate/faulty power supply
Not all PSUs are built equally, even at equal wattage. The number and loads for the different voltages ("rails") will make all the difference. You can get a 500W power supply that can support 24A on 12V, and another 500W power supply only supports 18A, so it's all about the numbers beyond the pure wattage.
Of course what you have in your system makes a difference too.
Faster CPUs take more voltages
5V devices - desktop hard drives, USB, laptop hard drives
12V devices - desktop hard drives, FireWire, fans
Pile enough devices and you can exceed the PSU's capability on a particular voltage rail, even if you haven't exceeded the PSU's maximum wattage.

6. Bad/Malfunctioning RAM
Two perfectly good sticks of RAM can be perfectly good in one motherboard and perfectly flawed in another.
Random crashes, memory errors, bluescreens and data corruption can result.
Run a good memory tester like MemTest86+Memtest86+ - Advanced Memory Diagnostic Tool through at least two full passes to verify that the RAM installed in your system is performing and behaving properly.
Although they tell you faster RAM will work on slower-rated systems, this is often not the case.
