Drives keep disappearing

[vonadams]

My cd rom was the first drive to periodically disappear, so I disconnected it as I have 2 others. Now my slave sata drive (not partitioned with c: - totally independent hard drive) disappears from my computer & I can't access anything off of it until I reboot system. Slave drive is still showing under device manager with no problems! I have tried various things but am leaning towards purchasing a new power supply. Any suggestions??

Sounds about right. What all do you have plugged into your PSU and what is the wattage?

I have a 550W psu I had 2sata drives (120gb & 200gb) but upgraded the 200gb to 500gb. The psu is about 2 years old now, previous power supplies only lasted me about 1 yr (cheap 1's & not enough wattage). When previous psu's started playing up similar things happened except it was my dvdrom or cdrom disappearing. Am going to install a new power supply with bigger wattage!!! Thanks for your help.

If you do install a new pw supply, do not go with a cheap unit. Quality brands; sparkle, FSP, PC Power & Cooling, Corsair, Seasonic. I used to recommend antecs however I have had a number of them fail lately.

Post whatever brand/model you intend to buy and we can give you a good idea if it is a quality unit or not.

Here is an example of a decent pw supply for a basic system. It is NOT intended to power a system with a high end video card, quad core cpu, etc. It is for a basic type system; dual core cpu. standard type video, etc.
