How do I get the drivers to download if I can't see anything? not being sarcastic- just puzzled.
This suggested that the computer would work in safe mode, sorry for the confusion.
I have to do hard shut down and then wait a minute or two and turn it back on - which gives me safe mode options.
Not having a PSU to swap in is a problem as it cannot be ruled in or out as the problem unless you get it tested by a local tech store, some will do this for free.
If the problem is with the integrated video chip you can fit an add on video card but be aware that not many video cards will function with a PSU that only has a 250W output.
For now check out the Ram (see my canned text below) and if necessary the keyboard, try swapping it if you can or disconnecting and then reconnecting it if you cannot.
How to physically test your Ram.
The following checks require the computer case to be opened so take the following safety precautions 1st, disconnect the power cord from the wall socket and take anti static precautions before touching anything inside, you can do this by touching a bare metal part of the case.
Have a pencil and notepad to hand.
Remove each stick of Ram and blow out the memory slots.
Insert the first stick of Ram in memory slot one, reconnect the power and in the case of a desktop computer the video to screen cable.
Power up the computer and see how it goes.
Make a note of the results.
Repeat the procedure until the first stick of Ram has been tested in each memory slot and the results written down.
Remove the first stick of Ram and put it to one side on top of a piece of paper with the number one on it for identification purposes.
Repeat the procedure with all Ram until each stick has been tested in all slots, the results written down and the sticks identified numerically.
Please note that some MBs (motherboards) will not boot unless there is Ram in slot one so please provide us with your motherboard details, brand, model name/number and any revision number, these details may be found by the CPU, between the PCI slots and/or around the edge of the motherboard, once we have the MB details we can look for the user manual.
